BQ76952: DSG pin status

Hello,

DSG will be pulled low to VSS with a ~70mA current source. However, to prevent damage to the DSG FET, the voltage on the LD pin (which is connected to PACK+) is monitored and will stop discharge when the DSG pin voltage goes below PACK+. This creates a series of pulses which over time discharge the DSG gate to the voltage of the LD pin.

More information can be found in 8 DSG Driver of Multiple FETs with the BQ76952, BQ76942 Battery Monitors (Rev. A).

Best regards,
