San Jose, Calif. November 5, 2016 – Kinetic Technologies, a high-performance analog and mixed-signal semiconductor company focused on developing power management solutions for computing, consumer, industrial, and communications markets, today introduced the KTS1601 and KTS1605, reverse-blocking, slew-rate controlled load switches with extremely low on-resistance.  The KTS1601 and KTS1605 are ideal for use in single cell Lithium-ion battery-based equipment, including mobile phones, Smartphones, Tablets, wearables and other portable devices or any appliance operated from a fixed 3.3V or 5V supply, such as HDD or SSD.

The KTS1601 and KTS1605 are the first generation of slew-rate controlled load switches products from Kinetic, significantly improving the efficiency in battery powered electronics.  The KTS1601 and KTS1605 power saving load switches are inserted between the battery or supply voltage and a load, and only turned on when the load is required by the system, thereby minimizing the power drain. The KTS1601 and KTS1605 features a controlled soft-on slew rate of typical 2.7ms that limits the inrush current for designs with heavy capacitive loads and minimizes any resulting voltage droop at the power rails.

With an operating voltage range from 1.5V to 5.5V, the KTS1601 and KTS1605 features the lowest on-resistance, and quiescent current of any similar packaged device on the market today. At an input voltage of 3.3V, the KTS1601 and KTS1605 features 24m and 13.4m respectively, providing a low IN to OUT voltage drop, maximising the voltage to the load. Both products are reverse-blocking when OFF, ensuring there are no discharge paths from OUT to IN, should a load be powered from a dual supply. The KTS1601 can operate up to a continuous current of 2A and the KTS1605, 5A.

With more and more functions being added to portable products, the battery capacity is struggling to meet the consumers expected operating time,” said Phil Dewsbury, Senior Director of Product Marketing at Kinetic Technologies. “With operating currents of these functions approaching their minimum, designers must look elsewhere to extend the battery life. The KTS1601 and KTS1605 load switches, provide an additional means to save power, by shutting down, un-used functions in a Smartphone or other portable product, without compromising the reliability or operating parameters of the system.”

The KTS1601 and KTS1605 also features an internal pull-down resistor on the enable pin to ensure the device remains off, should the input enable be allowed to float. The KTS1601 and KTS1605 also have an active pull-down option, that is connected between the output and ground, to discharge any residual load voltage at the output, when the switch is off.

Both devices include over-temperature protection, and ESD compliance at the input to IEC61000-4-2 level 4 of 8kV Contact Discharge and 15kV Air Discharge and are rated over the -40 degree C to +85 degree C temperature range. The KTS1601 is supplied in a WLCSP-4, 1.0 x 1.0mm, while the KTS1605 is supplied in a WLCSP-6, 1.0mm x 1.5mm, both RoHS and Green Compliant packages.

San Jose, Calif. August 28, 2016 – Kinetic Technologies, a high-performance analog and mixed-signal semiconductor company focused on developing power management solutions for computing, consumer, industrial, and communications markets, today introduced the KTS1670 and KTS1671, slew-rate controlled load switches with over-voltage protection to protect battery operated systems from malfunctions due to charger faults.  The KTS1670 and KTS1671 are ideal for use in single cell Lithium-ion battery-based equipment, including mobile phones, Smartphones, Tablets, wearables and other portable devices for charging currents up to 3A.

The KTS1670 and KTS1671 are the latest in a family of Power Interface products from Kinetic, targeted to significantly increase safety and reliability in battery powered electronics.  The KTS1670 and KTS1671 are inserted between the power supply or charger source and the load to be protected. The over-voltage protection (OVP) switch features an ultra-low 60mΩ (typical) on-resistance MOSFET and protects low-voltage systems against voltage faults up to +28VDC. If the input voltage exceeds the overvoltage threshold, the internal MOSFET reacts within typically 100ns and is turned off to prevent damage to any downstream components connected to the output of the device. An 18ms debounce time built into the device delays the internal MOSFET turn on time to avoid false turn on due to faulty connectors or line perturbations.

The overvoltage protection threshold can be externally programmed with an optional resistor divider to set a threshold between 4V and 20V. With the OVLO input pin tied to GND (or below the external OVLO select voltage), the KTS1670 and KTS1671 automatically selects the internal OVLO threshold. The internal overvoltage threshold of the KTS1670 is preset to 6.05V typical and the KTS1671 preset to 6.15V for use with standard 5V adapter chargers or USB charging ports.  The KTS1670 is specifically targeted for adjustable applications, where a tighter voltage tolerance is required.

The surge requirements for portable products, being used in India and SE Asia, have now increased to such a level, that integrating the surge protection with OVP is not commercially viable۝ said Phil Dewsbury, Senior Director of Product Marketing at Kinetic Technologies. The KTS1670 and KTS1671 products, in conjunction with an external TVS diode, provide a low-cost input protection scheme, that can ensure that down-stream electronics are not damaged by either a high-voltage surge or an incorrect adapter charger being used۝.

The devices support a voltage input range of 2.5V to +28V, include over-temperature protection, over-voltage protection, and automatic recovery when the fault conditions are removed. Each of the devices are available in an extremely small 6-pin WLCSP package. The devices are rated over the -40 degree C to +85 degree C temperature range.

Key Features of KTS1670/1671

• Operation up to +28V input
• Enhanced ESD protection on VBUS compliant with IEC61000 4-2 (Level 4)
  • 8kV Contact Discharge
  • 15kV Air Dicharge
• Fixed or adjustable Over-voltage protection
• Low 60mΩ resistance
• Small WLCSP6 package, 1.0mm x 1.2mm

San Jose, Calif. January 11, 2016 – Kinetic Technologies, a high-performance analog and mixed-signal semiconductor company focused on developing power management solutions for computing, consumer, industrial, and communications markets, today introduced the KTD2683B a three channel, high current LED Flash driver IC, with independent channel control.  The KTD2683B is a one chip solution, aimed at Smartphones featuring a dual LED main Flash and a single torch LED, reducing the total component count, pcb area and cost.

The KTD2683B consists of a high switching frequency synchronous boost converter, two independently controlled current sources and one current sink in a small WLCSP package size. LED 1 and LED 2 are powered from the boost converter, supplying 1.5A and 0.75A respectively, and LED3 directly from the input, supplying 0.3A. The inductor-based boost converter integrates two low RDSON power MOSFETs, and operates at a switching frequency of 2MHz or can be programmed to 4MHz minimizing the size of the external inductor and capacitors.

The control interface is designed for maximum flexibility and compatibility with various types of system controls. The KTD2683B is mainly programmed and controlled via an I2C-compatible interface, but also includes three logic inputs that can provide a hardware flash enable (STROBE) and a hardware torch enable (TORCH), as well as a flash interrupt (TX), which can be used to reduce the flash current during power amplifier pulse event to lower the battery load current. The I2C control features include the independent on/off and current control of the two current sources (LED1/LED2) in Flash/Torch/IR modes, their on/off ramp timing and current shape control, three input low voltage protection modes, flash safety time-out protection, boost converter current limit and switching frequency options, and various fault events read back. For the current sink LED3, the I2C interface can control its current value in Torch/IR modes. In addition, the KTD2683B also has various protection features including LED open and short protections, thermal regulation to prevent IC temperature from going too high, and thermal shutdown protection.

“Most LED driver ICs normally only provide the capability of driving a single or dual, rear-facing LED flash,” said Phil Dewsbury, Senior Director of Product Marketing at Kinetic Technologies. “With the increasing use of smartphones for video conferencing, or for taking selfies, the KTD2683B provides an extra LED driver to provide additional light to the front-facing camera, significantly enhancing the picture quality. Using the KTD2683B allows the designer to not only reduce the solution size, but also dispense with the need for another driver IC and the associated inductor and capacitors, significantly reducing the system cost.”

The KTD2683B is supplied in a WLCSP-12, 1.42 x 1.66mm, RoHS and Green Compliant package and is rated over the -40 degree C to +85 degree C temperature range.
