LTC4359HMS8 Description

Short technical summary and product information.

The LTC4359HMS8 is a positive high voltage ideal diode controller manufactured by LT. It is designed to drive an external N-channel MOSFET, effectively replacing a power Schottky diode and significantly reducing power dissipation. This controller features a wide operating voltage range from 4V to 80V and provides reverse input protection down to -40V.

 

Key operational characteristics include a low 150µA operating current and a very low 9µA shutdown current, making it suitable for power-sensitive applications. The LTC4359HMS8 ensures smooth current delivery without oscillation, even at light loads, and offers fast turn-off to minimize reverse current transients when a power source fails or is shorted.

 

This ideal diode controller is available in an 8-lead MSOP package. Its applications span automotive battery protection, redundant power supplies, supply holdup, telecom infrastructure, computer systems/servers, and solar systems. The device controls the forward-voltage drop across the external MOSFET to maintain efficient power transfer.

 

Designed for applications requiring high current diode functionality, the LTC4359HMS8 offers a robust solution for power management and protection circuits.
