ZXGD3108N8 40V ACTIVE OR ING MOSFET CONT ROLLER IN SO8 Description Features ZXGD3108N8 is a 40V Active ORing MOSFET Controller designed Active ORing MOSFET Controller for High- or Low-Side PSU for driving a very low R Power MOSFET as an ideal diode. This Ideal Diode to Reduce Forward Voltage Drop DS(ON) replaces the standard rectifier to reduce the forward voltage drop and -3mV Typical Turn-Off Threshold with 2mV Tolerance overall increase the power transfer efficiency. 40V Drain Voltage Rating 25V V Rating CC The ZXGD3108N8 can be used on both high-side and low-side power <5mW Standby Power with Quiescent Supply Current <400A supply units (PSU) with rails up to 40V. It enables very low R <600ns Turn-Off Time to Minimize Reverse Current DS(ON) MOSFETs to operate as ideal diodes as the turn-off threshold is Totally Lead-Free & Fully RoHS compliant (Notes 1 & 2) only -3mV with 2mV tolerance. In the typical 12V configuration, the Halogen and Antimony free. Green Device (Note 3) standby power consumption is <5mW as the low quiescent supply current is <400A. During PSU fault condition, the ORing Controller detects the power reduction and rapidly turns off the MOSFET in <600ns to block reverse current flow and avoid the common bus voltage dropping.
