BQ76952: BQ76952：Accum Charge

Star Xu

Part Number: BQ76952

How does the Accum Charge parameter in BQ76952 accumulate in the charging state or discharging state?

The customer want to use the MSP430 microcontroller to perform RessetPassQ when the battery is fully discharged. Do I need to switch the configuration mode? Or can it be operated in any mode?

Waiting for your reply.

Thanks

Hi Star,

Charging current should increase the value of Accum Charge, and discharging current should decrease it.

I recommend reading this thread that explains how to interpret the measurement: BQ76952: accumulated charge measurement calculation - Power management forum - Power management - TI E2E support forums.

I believe that RESETPASSQ() works as long as the communications are enabled, so in all modes aside from SHUTDOWN mode.
