  • The FTL75939 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 /SR0 LOW (by pressing power-on key) for 2.3 s ±20% turns on the PMIC.As a reset timer, it has one input and one fixed delay output. It generates a fixed delay of 7.5 s ±20% by disconnecting the PMIC from the battery power supply for 400 ms ±20%. 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.
