SGM2553/SGM2553D Precision Adjustable Current Limited Power Distribution Switches

2022-08-17

●GENERAL DESCRIPTION
■The SGM2553 and SGM2553D 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, over-current protection, 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. Fault conditions are indicated by the nFAULT pin. The  SGM2553D has quick output discharge function in disable status.
■SGM2553 and SGM2553D are available in the  Green TDFN-2×2-6L and SOT-23-6 packages. They are rated over the -40°C  to +85°C temperature range
