[7] Charger: CHARGER gets stuck with no VBAT capacitor

This anomaly applies to Revision 2, build codes CAAA-E00, CAAA-F00, CAAB-F00, QDAA-F00, QDAB-F00.

It was inherited from the previous IC revision Revision 1.

Symptoms

Battery stops charging, and CHARGER gets stuck in error state.

Conditions

Battery pack's overdischarge protection is active when VBUS gets connected to a power source.

Consequences

Charging does not start, and CHARGER gets stuck in error state.

Workaround

Add a 1.0 µF capacitor to the VBAT pin as shown in the reference circuit in nPM1100 Product Specification v1.2 or later.
