See note
Notes:
1. To support auto-power-on or for a connection to a charger, see Figure 5-7.
2. Designs which implement an eFUSE or current limiting device on the input power rail of the
module should select a part that DOES NOT limit reverse current.

5.4.1.1 Auto Power-On Option No MCU
For designs that will not have a power button but should power on when the main power
supply is connected, the optional ACOK circuit shown in Figure 5-7 should be implemented
and the
ACOK_L signal pulled to GND.
