Device Information

LM74680 is an ideal diode bridge controller that can drive four external N-channel MOSFETs to eliminate traditional diode bridges for superior thermals and efficiency. The top-gates are driven to emulate a very-low forward voltage (11.5mV typ.) diode with low IQ. The wide input supply of 4 V to 72 V allows protection and control of 24Vac systems.
