8.3.6 Default Behavior Configuration (ADCIN1, ADCIN2)

Note

This functionality is firmware controlled and subject to change.

The ADCINx inputs to the internal ADC control the behavior of the TPS25751 in response to VBUS being

supplied when VIN_3V3 is low (that is the dead-battery scenario). The ADCINx pins must be externally tied to

the LDO_3V3 pin via a resistive divider as shown in the following figure. At power-up the ADC converts the

ADCINx voltage and the digital core uses these two values to determine start-up behavior. The available start-up

configurations include options for I2C target address of I2Ct_SCL/SDA, sink path control in dead-battery, and

default configuration.
