SLUUD80 December 2024 LM74681
LM74681 is an ideal diode bridge controller that can drive four external N-channel MOSFETs in bridge configuration 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 30V to 80V allows protection and control of 48V PoE systems with ultra low Iq in detection and classification phase.
