LTC4370IMS#PBF

The LTC4370IMS#PBF is a two-supply current sharing controller from Analog Devices, designed to balance load currents between two power supplies. It incorporates MOSFET ideal diodes that block reverse and shoot-through currents during start-up and fault conditions. The controller operates with supply voltages ranging from 2.9V to 18V and has a typical current rating of 2.1 mA. Its fast gate turn-on reduces voltage droop during supply switchover, and a fast turn-off minimizes reverse current transients if an input supply fails.

This component is suitable for applications requiring redundant power supplies and high availability systems, such as servers and telecom infrastructure. It features enable inputs for low current states and MOSFET on status outputs. The load sharing function can be disabled to operate as a dual ideal diode controller. The LTC4370IMS#PBF is supplied in a 16-MSOP package and is designed for surface mount applications.

Key electrical specifications include an operating voltage range of 2.9V to 18V, a typical current draw of 2.1 mA, and a delay time of 400 ns. The operating temperature range is -40°C to 85°C. The device utilizes N-Channel FETs and does not have internal switches. The package is a 16-MSOP, suitable for surface mounting.
