Cool-Switch® PI2161 60 Volt, 12 Amp Full-Function Load Disconnect Switch Solution Product Description Features The Cool-Switch® PI2161 is a complete full-function Load Disconnect Switch solution for medium voltage applications with a high-speed electronic circuit breaker and a very low on-state resistance MOSFET. It is designed to protect an input power bus from output load fault conditions. The PI2161 Cool-Switch solution is offered in an extremely small, thermally enhanced 7mm x 8mm LGA package. The PI2161 enables an extremely low power loss solution with fast dynamic response to an over current fault or high conditions. The PI2161 senses a small portion of the total MOSFET current and has a low voltage threshold allowing the use of low power sense resistors. • Integrated High Performance 12 A, 8.5 mΩ MOSFET The switch is closed when the EN input is low and is open when EN is high. Once enabled, the PI2161 monitors the MOSFET current through a sense resistor. If an over current level is sensed, the switch is quickly latched off to prevent the power source from being overloaded. Bringing the EN pin high will reset the over current latch allowing retry. The PI2161 has an internal 10 kΩ bias resistor connected between the Drain (D) and VC to eliminate need for external resistor in a 44 V bus application (41 V to 48 V). • Very small, high density fully-optimized solution with simple PCB layout • Programmable latching over-current detection • Fast 120ns disconnect response to load failures • Low loss current sensing • Fast disable via EN pin, typically 200 ns. • Load Status output (VO scaled load voltage) Applications • • • • N+1 Redundant Power Systems Servers & High End Computing Load Disconnect High Side Circuit Breaker Package Information • The PI2161 is offered in the following package: 17-pin 7mm x 8mm thermally enhanced LGA package, achieving
