The LTC3901 is a secondary side synchronous rectifier driver designed to be used in isolated push-pull and full-bridge converter power supplies. The chip drives two external N-channel MOSFETs and accepts a transformer generated bipolar input to maintain synchronization with the primary side controller.The LTC3901 provides a full range of protection features for the external MOSFETs. A programmable timeout function is included that disables both drivers when the synchronization signal is missing or incorrect. Additionally, the chip senses the output inductor current through the drain-source resistance of the two MOSFETs, turning off the MOSFETs if the inductor current reverses. The LTC3901 also shuts off the drivers if the supply is low or if the synchronization sequence is incorrect.
