SGM2593/SGM2593D

Power Distribution Switches

GENERAL DESCRIPTION

FEATURES

The SGM2593 and SGM2593D are single channel

power distribution switches. The switch is controlled by

the EN pin and operates from 2.5V to 6V supply voltage.

It can be used in USB power distribution applications.

● High-side N-MOSFET

● On-Resistance:

 TDFN-2×2-6AL: 60mΩ (TYP)

 SOT-23-6: 65mΩ (TYP)

● Programmable Current Limit Range: 0.1A to 3A

1.5A at R_ILIM= 4.53kΩ

The device integrates programmable current limit to

protect the upstream power supply from damage during

over-current or short-circuit condition. It also has the

function of over-temperature protection.

● Input Voltage Range: 2.5V to 6V

● Quiescent Current: 27μA (TYP)

● Shutdown Current: 0.28μA (TYP)

● Soft-Start Function

The device is designed with soft-start circuit to cope

with inrush currents when large capacitive loads are

connected. The nFAULT output will be asserted to low

level during over-current, over-temperature or reverse

voltage condition.

● Over-Temperature Protection

● Under-Voltage Lockout Protection for VIN

● No Reversed Leakage Current (Reverse Blocking)

● Fault Flag (nFAULT Pin)

● Quick Output Discharge (SGM2593D Only)

● 1.2MΩ Pull-Down Resistor at EN Pin

● Available in Green TDFN-2×2-6AL and SOT-23-6

Packages

The SGM2593D further reduces the total solution size

by integrating a 47Ω pull-down resistor for output

discharge when the switch is shut down by EN.

The SGM2593 and SGM2593D are available in Green

TDFN-2×2-6AL and SOT-23-6 packages.
