  • BQ76972: [BQ76972] PDSG Failure Due to Delayed LD Voltage Update During BOTHOFF Toggle in SLEEP Mode

    Part Number: BQ76972 [Background] I have observed an issue where the PDSG (Pre-discharge) fails to operate when the BOTHOFF pin/command is toggled quickly ( ON → OFF ) while the device is in SLEEP mode. Instead of PDSG engaging, the DSG and CHG FETs turn…

  • BQ76972: Intermittent I2C communication CRC error between MCU and BQ76972.

    Part Number: BQ76972 Hi team, I am using a GD32 MCU to talk to BQ76972 with CRC enabled at 100 kHz. A CRC-fail occurs roughly once every few minutes. All failures are on the first CRC byte of a Direct-Command read. That CRC is computed from {0x10…
