The LTC4357IMS8#TRPBF is a positive high voltage ideal diode controller from Linear Technology. It is designed for use in automotive, redundant power supplies, and telecom infrastructure applications. The LTC4357IMS8#TRPBF drives an external N-channel MOSFET to replace a Schottky diode. This reduces power consumption, heat dissipation, voltage loss, and PC board area.

The LTC4357IMS8#TRPBF is easy to use and can be configured to OR multiple power sources or to provide a diode-like function. In diode-OR applications, the LTC4357IMS8#TRPBF controls the forward voltage drop across the MOSFET to ensure smooth current transfer from one path to the other without oscillation. If the power source fails or is shorted, a fast turn-off minimizes reverse current transients.

The LTC4357IMS8#TRPBF has a number of features that make it ideal for use in high-reliability applications. It has a wide operating voltage range of 9V to 80V, a high current rating of 5A, and a fast turn-off time of 300ns. The LTC4357IMS8#TRPBF is also protected against overvoltage, overcurrent, and reverse current conditions.

Here are some of the key features and benefits of the LTC4357IMS8#TRPBF:

• Replaces Schottky diodes with N-channel MOSFETs, reducing power consumption, heat dissipation, voltage loss, and PC board area.
