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 ~70mV VBIAS will rise and the PMOS will turn
off, isolating IN from OUT.

Feature(s)

  • Max Input Voltage: 40V
  • Peak Bias Current: -300mA
  • Max Reverse Voltage Protection: 50V
  • Totally Lead-Free & Fully RoHS Compliant 
  • Halogen- and Antimony-Free. "Green" Device 
  • 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.
