    Hi,

    What do you mean by implement power-off charger?

    The TWL6030 is able to charge the battery even when the device is not ON. It is able to detect if there is a battery connected, check the current charge and charge it if needed all by hardware. Also the TWL6030 will not power the omap chip if the battery doesn't have certain level of charge, it is a protection to the battery. There are some thresholds values to take certain actions. You can contact a TI representative to get the TWL6030 datasheet for more information.

    If you are having problems, can you explain little more what you are trying to do and the problem you are facing?. Thank you.
