PI2061
Description
The PI2061 is a high-speed electronic circuit breaker controller IC designed for use with N-channel MOSFETs in high side load disconnect switch solutions for medium voltage applications. The PI2061 Cool-Switch® controller enables an extremely low power loss solution with fast dynamic response to an over current fault or EN Low conditions.
Once enabled, the PI2061 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 low will reset the over current latch allowing retry. To avoid false tripping by the in-rush current, the over current level is approximately doubled during start up, until SN approaches about 0.8V below VC. The PI2061 has an internal charge pump to drive the gate of a high side N-Channel MOSFET above the VC input. There is an internal shunt regulator that regulates the VC input with respect to the SGND pin for...
