BQ76PL455A: input impedance and mux Rdson

Jerry Chen

Part Number: BQ76PL455A

Hi,

For the voltage sensing by BQ76PL455A's ADC, have we made a comparison with MAX17823 in input impedance and MUX Rdson?

End-customer said BQ76PL455A's battery voltage measurement accuracy is better than MAX17823, so I would like to know the reason.

Thanks.

Hi Jerry,

Unfortunately, we have not. The Maxim device is not public, so we do not have information to compare.

I do not think that the input impedance or MUX would be the cause. It could be the noise on the cell, possibly.
