Latched Overcurrent Fault Detector Has Fast Response Time
Oct 1, 2005
OVERCURRENT DETECTOR - the circuit introduced here is a simple and fast-responding overcurrent detector for protection of low-voltage applications. Unlike dedicated hot-swap controllers that impose a long startup delay initiated by undervoltage, this circuit provides protection only 150 µs after the input supply rises above 2.7 V. It also possesses a measure of inrush current limiting during power up, by virtue of the limited gate voltage on an external p-channel switch....
