DZDH0401DW-7

DZDH0401DW-7 is a ideal diode controller. It is intended to drive a P-channel enhancement MOSFET configured as an ideal diode. The device operates as a differential amplifier and PMOS controller to minimize forward current losses when VIN > VOUT and provide high isolation when VIN < VOUT. The circuit compares the voltage between IN and OUT. Typical applications include high side gate driving PMOS, high side disconnect switch, battery discharge protection, emergency lighting, active OR’ing redundant power supplies.
