DZDH0401DW
IDEAL DIODE CONTROLLER IN SOT363
Description
Features
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

Peak Bias Current: -300mA
Max Reverse Voltage Protection: 50V
losses when VIN > VOUT and provide high isolation when VIN < VOUT
.
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. "Green" Device (Note 3)
For automotive applications requiring specific change
control (i.e. parts qualified to AEC-Q100/101/200, PPAP
capable, and manufactured in IATF 16949 certified
facilities), please contact us or your local Diodes
representative.
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.
