The DZDH0401DW 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. If the differential is greater than ~34mV (typ.) VBIAS will fall and the PMOS will turn on, If the differential is less than ~70mV VBIAS will rise and the PMOS will turn
off, isolating IN from OUT.
