GENERAL DESCRIPTION

The SGM4073 can be used as reset timer as well as

load management switch. The device is very suitable

for highly integrated applications.

When the mobile device is turned off, press the start

key to keep the PMIC at a logic low level for 1.9s to turn

on the PMIC.

Since the Quiescent Current of the SGM4073 is as low

as 1μA (TYP), it supports direct interface with

low-voltage chipsets and can maintain low power

consumption.

When the device is used as a reset timer,

disconnecting the PMIC from the battery power for

468ms will produce a fixed delay time of 7.7s. The

delay time can be adjusted by an external resistor

connected between the DELAY_ADJ pin and ground.

The SGM4073 also can be used as a load

management switch. It can disconnect loads with high

shutdown current and high load capacitance (< 200μF)

powered by a supply voltage lower than 6V. The

SGM4073 provides a 20mΩ on-resistance when VBAT is

3.6V.

The SGM4073 is available in a Green

WLCSP-1.31×1.62-12B package. It operates over an

ambient temperature range of -40℃ to +85℃.
