Reset Timer with Integrated Load Switch

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.
