40 / 44 page ACT8846 Rev 7.0 06-Dec-2017 Innovative PowerTM - 40 - www.active-semi.com Copyright © 2016-2017 Active-Semi, Inc. ActivePMUTM is a trademark of Active-Semi. I2CTM is a trademark of NXP. nRSTO OUT2/4/5/7 40ms VIN PWRHLD and PWREN OUT3/6 2ms OUT1 2ms nPBIN UVLO CMI 106 Startup with nPBIN 32ms CMI 106: ACT8846QM106 continued. 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 togeth- er. nPBIN nPBIN retains the short and long press functionality described earlier in the datasheet. NRSTO nRSTO is gated by OUT6 and OUT7 and has a 40ms delay. DVS DVS functionality is only available via I2C. VSELR/GPIO1/GPIO2 The VSELR/GPIO1/GPIO2 pins are not functional and should be permanently pulled high or low. GPIO1/2/3/4/5/6 These outputs are off by default but can be enabled via I2C. GPIO3 frequency and duty cycle are 256Hz and 50%. GPIO4/5/6 frequency and duty cycle are 0.25Hz and 6.25%. Watchdog All watchdog functionality is disabled by default. |
