Kinetic Technologies Lowest Resistance USB Current-Sink Protection Switch KTS1696A Enabling Power Delivery up to 140W

KTS1696A: Low 11mΩ Resistance Load Switch with Overvoltage and Reverse Blocking, Protects Against ±90V Input Surges

Power management and video/audio interface leader, Kinetic Technologies, has announced the highest power addition to its comprehensive range of power protection solutions with the KTS1696A USB Current-Sink Protection Switch. This robust protection device has been designed to isolate and protect against abnormal voltage and current conditions through a slew-rate controlled, reverse-blocking, 11mΩ, low-resistance MOSFET switch in a tiny 2.7×2.7mm 25-bump WLCSP package.

“In addition to its ability to protect USB inputs from abnormal power supply voltage and surge currents, the KTS1696A features an incredibly low 11mΩ resistance switch with reverse-blocking capability up to 29V,” says Jia Hu, Kinetic Technologies Senior Director of ESIA Product Marketing. “Increasing USB Power Delivery above 100W is a future trend, pushing the USB limits, with Kinetic leading the way. This low resistance switch allows product designers to do that without worrying about excessive power loss through heat dissipation.”

In addition to the low-resistance MOSFET switch, the KTS1696A features slew-rate turn-on control, preventing excessive voltage overshoot and large inrush currents. The device also features several additional protection functions – including input ±90V surge protection, input over – and under–voltage protection, over-temperature protection, short-circuit protection, and current-liming protection. The over-voltage protection is typically set at 23V but can also be used in adjustable mode using two external resistors to set the trip point between 4V and 23V. The short-circuit and current-limiting protection is designed to turn off the switch during hard or soft short circuits at the output. At detection, the switch is turned OFF and if no other fault is detected, the device will auto-retry to start until such time as the fault is removed or the input power is removed. During any fault condition the ACOK, power good flag will be de-asserted.

Featuring an active high enable, the KTS1696A operates over a wide input voltage range of 3V to 29V and covers USB PD applications, enabling the device to offer essential protection to enhance system reliability.

The KTS1696A is available in a green-compliant, 2.7mm x 2.7mm, Wafer-Level, Chip-Scale Package (WLCSP).

Key applications for the Kinetic Technologies KTS1696A include mini-desktop PCs, notebooks, tablets, docking stations, monitors, portable devices, and USB Type-C/PD current sink ports.
