SGM2551A/SGM2551C Precision Adjustable Current Limited Power Distribution Switches
●GENERAL DESCRIPTION
■The SGM2551A and SGM2551C are single channel power distribution switches. The switch operates from a wide range of 2.5V to 5.5V supply voltage, and is controlled by the EN pin.
■A 90mΩ low RON N-MOSFET is integrated. It is capable of supplying up to 1.5A continuous current. The small size and quiescent current make the device very suitable for space limited, battery-powered applications.
■A number of protection features are provided in the device including soft-start, adjustable current limit and thermal shutdown.This device provides a programmable current limit threshold between 100mA and 1.7A through the RILIM. The internal reverse-voltage function will protect devices on the input side of the switch. The SGM2551C has quick output discharge function in disable status.
■SGM2551A and SGM2551C are available in the Green TDFN-2×2-6L and SOT-23-5 packages. They are rated over the -40°C to +85°C temperature range.
