FTL75939 Configurable Reset Timer
onsemi FTL75939 Configurable Reset Timer 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 2.3s ±20% turns on the PMIC. As a reset timer, it has one input and one fixed delay output. It generates a fixed delay of 7.5s ±20% by disconnecting the PMIC from the battery power supply for 400ms ±20%. Then the load switch is turned on again to reconnect the battery to the PMIC such that the PMIC goes into power-on sequence. As an advanced load management switch, the FTL75939 disconnects loads powered from the DC power rail (<6V) with stringent off-state current targets and high load capacitances (up to 200uF). The onsemi FTL75939 consists of a slew-rate controlled low-impedance MOSFET switch (21mΩ typical at 4.5V) that has exceptionally low off-state current drain (<0.2uA typical) to facilitate compliance with standby power requirements.
