BQ76952: CFETOFF and DFETOFF with Alert Pin

mark 16417

Part Number: BQ76952

Hi TI exper

Using BQ76952 CFETOFF and DFETOFF pins to control CHG and DSG FETs, I found the alert pin also change the status(LOW or HI) when FETs control by CFETOFF or DFETOFF pins.Is this behavior right?

CFETOFF or DFETOFF = HI => Alert pin = LOW

CFETOFF or DFETOFF = Low => Alert pin = HIGH

Hi Mark,

The BQ76952 is highly configurable. Check the Alarm mask settings and ALERT configuration. I see the FUSE bit is indicated high. In general CFETOFF or DFETOFF would not seem to cause a change to the ALERT output, but may set a condition which sets ALERT.
