ZXGD3101N8TC

ZXGD3101N8TC is a synchronous rectifier controller. It is intended to drive MOSFETs configured as ideal diode replacements. This device is comprised of a differential amplifier detector stage and a high-current driver. The detector monitors the reverse voltage of the MOSFET such that if body diode conduction occurs a positive voltage is applied to the MOSFET’s gate pin. Once the positive voltage is applied to the gate the MOSFET switches on allowing reverse current flow. The detectors’ output voltage is then proportional to the MOSFET drain-source reverse voltage drop and this is applied to the gate via the driver. This action provides a rapid turn-off as the current decays. It is used in applications such as adaptors, LCD monitors, server PSUs, set top boxes, high-power adapters, LCD TVs, and street lighting.
