The RT9422A Li-Ion/Li-Polymer battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell battery packs.

of the RT9422A can be used to indicate more serious faults via the SAFE pin. This pin can be used to blow an in-line fuse to permanently disable the battery pack from charging or discharging. The SAFE pin also can used to detect secondary protection IC status and log battery status in the NVM when protection be triggered. To prevent battery pack cloning, the RT9422A integrates SHA-1/HMAC authentication with a 128-bit secret key. Features.
Support Pack Side Fuel Gauging.
Battery Fuel G.
