[PATCH v3 0/4] Add pm8916 VM-BMS and LBC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This series adds charger and "fuel-gauge" found in Qualcomm pm8916 PMIC.

The LBC - Linear Battery Charger is a simple CC/CV charger, that works
autonomously after the current and voltage limits are set.

The VM-BMS - Voltage Mode BMS is a simple hardware block that provides
average voltage on the battery terminals.

These two hardware blocks are used as the battery charging and
management solution in some old Qualcomm devices.
