DZDH0401DW - IDEAL DIODE CONTROLLER

Description

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.

Features

Max Input Voltage: 40V.
Peak Bias Current: -300mA.
Max Reverse Voltage Protection: 50V.
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2).
Halogen and Antimony Free. "Green" Device (Note 3).
For automotive.

DZDH0401DW IDEAL DIODE CONTROLLER IN SOT363 Description 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 ~34mV VBIAS will rise and the PMOS will turn off, isolating IN from OUT.
