Notes
66. Larger capacitive loading values will lead to longer turn on times exceeding the given limits; smaller values will lead to larger ripple at
the output.
67. Input supply is assumed in the range of 3.0 < BP < 4.65 V; lower BP values may extend turn on time, and functionality not supported
for BP less than ~2.7 V.
A power gate driver pulled low may be thought of as power gating being active since this is the condition where a power source
is isolated (or power gated) from its loading on the other side of the switch. The power gate drive outputs are SPI controlled in
the active modes as shown in Table 38 .

When SPI controlled (Watchdog, On, and User Off Wait states), the PWGTDRVx power gate drive pin states are determined
by SPI enable bits PWGTxSPIEN, according to Table 39 .

68. Applicable for Watchdog, On and User Off Wait modes only. If PWGT1SPIEN
AND PWGT2SPIEN both = 1 then the charge pump is disabled.
GENERAL PURPOSE OUTPUTS
GPO drivers included can provide useful system level signaling with SPI enabling and programmable Standby control. Key
use cases for GPO outputs include battery pack thermistor biasing and enabling of peripheral devices, such as light sensor(s),
camera flash, or even supplemental regulators.
SPI enabling can be used for coordinating GPOs with ADC conversions for consumption efficiency and desired settling
characteristics.
Four general purpose outputs are provided, summarized in Table 40 and Table 41 (active high polarities assumed).
