LTC4355IS

Positive High Voltage Ideal Diode-OR with Input Supply and Fuse Monitors

DESCRIPTION

The LTC®4355 is a positive voltage ideal diode-OR controller that drives two external N-channel MOSFETs. Forming the diode-OR with N-channel MOSFETs instead of Schottky diodes reduces power consumption, heat dissipation and PC board area.
