6.4.3 Active Mode

The device is powered up and charges the battery when the TS pin is above VTS_ENZ and the IN voltage ramps above both VIN_LOWV and VOUT + VSLEEPZ. The device draws IQ_IN from the supply to bias the internal circuitry. For details on the device power-up sequence, refer to Section 6.3.1.
