BQ76952: 自主模式和半自主模式的控制

Part Number: BQ76952

请教一下，① BQ76952型AFE芯片在设置成完全自主模式下，能否执行主机的控制命令呢？

② 如果将BQ76952设置成半自主模式的情况下，能否实现“未接收到主机命令时自主控制MOS通断，接收到命令时听从主机命令”呢？

感谢~

    您好，请参考TRM 5.2.3.2 of the TRM

    To configure the device to only turn on/off the FETs using commands from the host processor, then:

    • Settings:FET:FET Options[FET_CTRL_EN] should be set to 1, so that the device can turn on/off the FETs at all.
    • Go through each of the Settings:Protection:CHG FET Protections A - C and Settings:Protection:DSG FET Protections A - C registers, and clear (0) the bits for the protections that you do not want to be able to automatically turn the FETs on or off.
