BQ76952: High side current sensing

Part Number: BQ76952
Other Parts Discussed in Thread: BQ40Z80

Hello,

I am looking for a BMS that is able to monitor up to 14S cells. The BQ76952 looks good but there is one problem: in our application, the "B-" rail is not available on the PCB and therefore the low-side current sensing as used by the BQ76952 is not possible.

I saw a similar article on the forum about high side current sensing ("BQ40Z80: adapt BQ40Z80 for high side current sensing") which is a solution but it adds costs which I would like to avoid.

So my main question is: are there any devices in the "BQ" series that support high-side current sensing ? I'm only aware of low-side parts.

Regards,

Jeroen
