7.3.1 Device Power Up from Input Source

When an input source is plugged in and charge is enabled, the device checks the input source voltage to turn on all of the bias circuits. The device detects and sets the charge current limits before the linear regulator is started. The power-up sequence from the input source is listed below:

  1. ISET pin detection
  2. Charger power up
