  • BQ76942: Is the BQ76942 compatible with Lithium Titanate (LTO) batteries?

    TI Thinks Resolved
    Part Number: BQ76942 Hi Team, Could you help advise on the question below? Is the BQ76942 compatible with Lithium Titanate (LTO) batteries? Do the pre-gate drivers also work with low-voltage batteries? Best regards, Wittawat

  • BQ76942: BQ76942: Schematic Review

    Part Number: BQ76942 Other Parts Discussed in Thread: BQSTUDIO , EV2400 Hello, I am currently designing a 4-cell battery monitor using the BQ76942 IC for an SAE competition. Could you please review my schematic and provide any suggestions or identify…

  • BQ76942: BQ76942 CONFIG_UPDATE

    TI Thinks Resolved
    Part Number: BQ76942 Hi Expert: To reduce the power consumption of the BMS during sleep mode, when the BMS enters sleep, it needs to turn off the voltage output of the AFE's reg1, cutting off the power supply to the IIC isolation conversion chip…

  • BQ76942: Using BQ76942 Balancing for NiMH

    Part Number: BQ76942 Hi, I would like to use the BQ76942 (2 stacked) for 20s NiMH battery pack. So I am checking whether the internal balancing works at cell voltages of 1V as well (this also determines whether external balancing is possible). That…

  • BQ76942: High-side Protection MOSFET Driving Capability of BQ76942 Under 3S Low-Voltage Operating Conditions

    Part Number: BQ76942 I hope to use the BQ76942 to monitor 3 series-connected battery cells with a rated voltage of 3.2 V, and directly control the charge and discharge protection MOSFETs (CHG/DSG) via the high-side driver integrated in the chip. When…

    Part Number: BQ76942 I plan to use the BQ76942 to monitor 3 series-connected battery cells with a rated voltage of 3.2 V, and directly control the charge and discharge protection MOSFETs (CHG/DSG) via the high-side driver integrated in the chip. When…

  • BQ76942: Documenation regarding functional safety of BQ76942

    TI Thinks Resolved
    Part Number: BQ76942 Hello, We're working on implementing the BQ76942 in a BMS to be used on a battery pack that needs to be compliant with IEC 62133. It hence seem that there will be requirements for the BMS to be functionally safe per ISO 13849 or…

  • BQ76942: BQ76942: Not able to unseal bq-chip once a PF is set

    Part Number: BQ76942 Other Parts Discussed in Thread: BQ76972 Hello and sorry for the radio silence, I got my handy on 2 of our boards: One is fully functional and the other has VIMA PF set. The issue is still the same like in the original topic. For…

  • BQ76942: BQ76942 Thermistor Misread Due to Power Sequencing

    Part Number: BQ76942 Summary We are seeing thermistor misreads on our BQ76942-based BMS that appear to be directly tied to power sequencing of the BAT and REGIN pins. When sequenced correctly the issue does not occur and we have 30 boards that demonstrate…
