Hello.

I have one question about QON terminal's reset function of Q25601D. When using QON reset. What's block can be reset except BATTFET? (For example,Registor bit,other FET control.)

    Hi,

    /QON only controls the BATFET, not other blocks (please see Section 9.4.4 in the datasheet for more details). However, by controlling BATFET, /QON can reset any systems connected to SYS.

    /QON has two functions to control the BATFET: BATFET enable and BATFET reset.

    1. BATFET enable: When the device is in shipping mode, /QON can enable the BATFET in order to exit shipping mode.
    2. BATFET reset: When no adapter is plugged in, /QON can turn the BATFET off and then re-enable it in order to reset system power. Therefore, any systems connected to SYS can be forced to have a power-on reset.

    Best regards,
