We used the TI BQ27421-G1A gauge in the product.
1) In the Technical Reference Manual of the gauge, it said:
4.1.16 RESET: 0x0041
This subcommand instructs the fuel gauge to perform a full device reset and reinitialize RAM data to the
default values from ROM and is therefore not typically used in field operation. The gauge sets the Flags()
[ITPOR] bit and enters the INITIALIZE mode. Refer to Figure 2-1. This subcommand is only available
when the fuel gauge is UNSEALED.
2) If the power to the gauge is always on, are there any other methods to reinitialize the content of Data Memory (RAM data) of the gauge to the default values?
Thank you.
