Kinetic Technologies’ Low RON Load Switch KTS1677A Isolates and Protects Against Abnormal Voltage and Current Conditions
KTS1677A: Low RON Load Switch with Overvoltage and Reverse Blocking, Protects Against ±90V Input Surges
Power management leader Kinetic Technologies has announced a new addition to their ever-growing power protection solutions with the KTS1677A. This innovative protection device has been designed to isolate and protect against abnormal voltage and current conditions through a slew-rate controlled, reverse-blocking, 30mΩ, low-resistance MOSFET switch.
“In addition to its ability to protect USB inputs from abnormal power supply voltage and surge currents, the KTS1677A features reverse-blocking capability up to 30V,” says David Nam, Vice President of Kinetic Technologies. “This allows two devices, used in a Power OR configuration to support dual USB inputs connecting to a single system.
In addition to the low-resistance MOSFET switch, the KTS1677A 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, and over-temperature 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 KTS1677A operates via a wide-input voltage range of 3V to 30V and covers USB PD applications, enabling the device to offer essential protection to enhance system reliability.
The KTS1677A is available in a green compliant, 2.57mm x 1.57mm, Wafer-Level, Chip-Scale Package (WLCSP).
Key applications for the Kinetic Technologies KTS1677A include computers, tablets, mobile internet devices, storage, DLSR, portable devices, and USB Type-C power source switches.
