BQ76952: BQ76952 Shutdown模式充电唤醒问题

Part Number: BQ76952




  • 您好,请参考下面内容:

    The wake voltage on LD pin can be any voltage from 0.8V to 2.25V. There's no way to control the wake-up voltage on LD pin. This is internal... unless an external circuitry is controlling this pin which is what your customer seems to be doing.

    The LD pin voltage in normal mode can have a range in voltage from 0V to 85V depending on how the LD pin is connected. We recommend to connect LD pin to PACK+ to protect the DSG FET. This is how we have it connected in our EVM. So, in normal mode the LD pin in our EVM will follow the PACK+ voltage.
