The LTC4357IMS8#PBF by LT is a positive high voltage ideal diode controller designed to replace Schottky diodes with an external N-channel MOSFET. This component is ideal for diode-OR and high current diode applications, significantly reducing power consumption, heat dissipation, voltage loss, and PC board area.
The LTC4357 facilitates the ORing of power sources to enhance total system reliability. In diode-OR configurations, it precisely controls the forward voltage drop across the MOSFET, ensuring smooth current transfer between paths without oscillation. A fast turn-off feature, occurring within 0.5µs, minimizes reverse current transients when a power source fails or is shorted.
This ideal diode controller operates over a wide voltage range from 9V to 80V. It is available in compact 6-lead (2mm x 3mm) DFN and 8-lead MSOP packages, making it suitable for space-constrained designs. Applications include N+1 redundant power supplies, high availability systems, AdvancedTCA systems, telecom infrastructure, and automotive systems.
The device supports various operating temperature ranges, including 0°C to 70°C for the LTC4357C, -40°C to 85°C for the LTC4357I, and -40°C to 125°C for the LTC4357H. Absolute maximum ratings include supply voltages up to 100V for IN and VDD, and output voltage for GATE relative to VIN.
The operating voltage range is 9V to 80V.
The typical turn-off time is 0.5µs.
The maximum supply voltage on IN, OUT, and VDD pins is 100V.
The LTC4357 is available in a 6-lead DFN (2mm x 3mm) and an 8-lead MSOP package.
