BQ76952: What is 5.5V or 11V Mode

Hi Naveen,

This is the charge pump voltage for the high side FET drivers. From the documentation:

The overdrive level of the charge pump voltage can be set to 5.5 V or 11 V, using the Settings:FET:Chg Pump Control[LVEN] configuration bit. In general, the 5.5 V setting results in lower power dissipation when a FET is being driven, while the higher 11 V overdrive reduces the on-resistance of the FET. If a FET exhibits significant gate leakage current when driven at the higher overdrive level, this can result in a higher device current for the charge pump to support this. In this case, using the lower overdrive level can reduce the leakage current and thus the device current.

Best regards,

Matt
