DZDH0401DW IDEAL DIODE CONTROLLER IN SOT363 Description Features The DZDH0401DW is intended to drive a p-channel enhancement Max Input Voltage: 40V MOSFET configured as an ideal diode. The device operates as a Peak Bias Current: -300mA differential amplifier and PMOS controller to minimize forward current Max Reverse Voltage Protection: 50V losses when V > V and provide high isolation when V < V . Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) IN OUT IN OUT Halogen- and Antimony-Free.Gree Device (Note 3) The circuit compares the voltage between IN and OUT. If the differential is greater than ~34mV (typ.) V will fall and the PMOS will turn on, If For automotive applications requiring specific change BIAS the differential is less than ~70mV V will rise and the PMOS will turn control (i.e. parts qualified to AEC-Q100/101/200, PPAP BIAS capable, and manufactured in IATF 16949 certified off, isolating IN from OUT. facilities), please contact us or your local Diodes representative.
