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.
