The LM74680 is an ideal diode bridge controller that provides voltage rectification by driving four N-channel MOSFETs in a full-bridge configuration. LM74680 enables lower voltage drop and reduced power dissipation as compared to conventional diode bridge rectifiers. This helps to simplify the power supply design, eliminate heat sinks, and reduce PCB area. The integrated charge pump allows use of N-channel MOSFETs, which are smaller and more cost-effective than P-channel MOSFETs for the same power level. It also offers fast response to reverse current conditions for protection against input short events. The LM74680 has an enable pin which allows for the gate driver to be either enabled or disabled by an external signal. The LM74680 supports voltage rectification from DC to 1kHz.
This device is characterized for operation over a junction temperature range of –40°C to +125°C.
