The SGM4073 is both a timer for resetting a mobile device and an advanced load management switch for applications requiring a highly integrated solution.
If the mobile device is off, holding nSR0 low (by pressing power-on key) for 1.9s turns on the PMIC.
As a reset timer, it has one input and one fixed delay output. It generates a fixed delay of 7.7s by disconnecting the PMIC from the battery power supply for 468ms. Then the load switch is turned on again to reconnect the battery to the PMIC such that PMIC goes into power-on sequence. The reset delay can be customized by connecting an external resistor to the DELAY_ADJ pin. Refer to Table 4. SGM4073YG/TR资料下载
