SGM2555

Power Distribution Switch

GENERAL DESCRIPTION

FEATURES

The SGM2555 is a single channel power distribution

switch. The switch operates from a wide range of

2.2V to 5.5V supply voltage, and is controlled by the

EN pin. It can be used in USB power distribution

applications.



Input Voltage Range: 2.2V to 5.5V

On-Resistance: 95mΩ (TYP)

Continuous Current: 1.1A

Current Limit: 1.85A

Quiescent Current: 19μA

Shutdown Current: 1μA (MAX)

Full Set of Protections

A 95mΩ low R_ONN-MOSFET is integrated. The small

size and quiescent current make the device very

suitable for space limited, battery-powered applications.

 Soft-Start

 Under-Voltage Lockout for VIN

 No Reversed Leakage Current

 Thermal Shutdown

A number of protection features are provided in the

device including soft-start, current limit of 1.85A and

thermal shutdown. The internal reverse-voltage

function will protect devices on the input side of the

switch.



Evaluated to IEC 60950-1, Ed 2, Am1, Annex CC,

Test Program 1 with CB Report

Available in a Green TDFN-2×2-6L Package

The SGM2555 is available in a Green TDFN-2×2-6L

package and is rated over the -40℃ to +85℃

temperature range.
