MODES OF OPERATION
The TPS65182/TPS65182B has three modes of operation, SLEEP, STANDBY, and ACTIVE. SLEEP mode is the
lowest-power mode in which all internal circuitry is turned off. In STANDBY, all power rails are shut down but the
device is ready to accept commands through PWR[3:0] pins and/or I2C interface. In ACTIVE mode one or more
power rails are enabled.
SLEEP
This is the lowest power mode of operation. All internal circuitry is turned off and the device
does not respond to I2C communications. TPS65182/TPS65182B enters SLEEP mode
whenever WAKEUP pin is pulled low.
STANDBY
In STANDBY all internal support circuitry is powered up and the device is ready to accept
commands either through GPIO or I2C control but none of the power rails are enabled. To
enter STANDBY mode the WAKEUP pin must be pulled high and all PWRx pins must be
pulled low. The device also enters STANDBY mode if input under voltage lock out (UVLO),
positive boost under voltage (VB_UV), or inverting buck-boost under voltage (VN_UV) is
detected, or thermal shutdown occurs.
ACTIVE
The device is in ACTIVE mode when any of the output rails are enabled and no fault
condition is present. This is the normal mode of operation while the device is powered up. In
ACTIVE mode, a falling edge on any PWRx pin shuts down and a rising edge powers up the
corresponding rail.
MODE TRANSISITONS
SLEEP
→ ACTIVE
WAKEUP pin is pulled high (rising edge) with any PWRx pin high. Rails come up in a
pre-defined power-up sequence.
SLEEP
→ STANDBY
WAKEUP pin is pulled high (rising edge) with all PWRx pins low. Rails will remain down until
one or more PWRx pin is pulled high.
ACTIVE
→ SLEEP
WAKEUP pin is pulled low (falling edge). Rails are shut down following the pre-defined
power-down sequence.
ACTIVE
→ STANDBY
WAKEUP pin is high. All PWRx pins are pulled low (falling edge). Rails shut down in the
order in which PWRx pins are pulled low. In the event of thermal shut down (TSD), under
voltage lock out (UVLO), positive boost or inverting buck-boost under voltage (UV), the
device shuts down all rails in a pre-defined power-down sequence.
STANDBY
→ ACTIVE
WAKEUP pin is high and any PWRx pin is pulled high (rising edge). Rails come up in the
same order as PWRx pins are pulled high.
STANDBY
→ SLEEP
WAKEUP pin is pulled low (falling edge) while none of the output rails are enabled.
