53 / 63 page  ACT8846 Advanced PMU for Multi-core Application Processors Data Sheet Rev. 13.0, Nov. 11, 2019 | Subject to change without notice 53 of 63 www.qorvo.com CMI 112: ACT8846QM112 continued OUT13 / GPIO1 40ms VIN PWRHLD and PWREN OUT7 OUT2 0.5ms nPBIN CMI 112 Startup with PWRHLD nRSTO OUT3 OUT1 OUT11 0.5ms 0.5ms OUT8 0.5ms OUT10 0.5ms 1ms OUT9 0.5ms Shutdown The IC can be turned off by pulling nPBIN low through a 50kohm resistor to GA or by deasserting PWREN and PWRHLD pins low. The IC can also be turned off via I2C. PWREN Asserting PWREN high enables the IC. In pushbutton applications, if PWREN is not asserted high before the nPBIN pin goes high, the IC shuts down. Note that PWREN and PWRHLD must be connected together. nPBIN nPBIN retains the short and long press functionality described earlier in the datasheet. NRSTO nRSTO is gated by OUT9 and has a 40ms delay. DVS DVS functionality is only available via I2C. |
