BQ24160: bq2416xx Charging

Hi,

How can I move from the charged state to the charging process again?

Please tell us about each case when HZ_MODE = 0 and HZ_MODE = 1.

best regards

    Hi,

    The charger will automatically start recharging once the battery discharges below the recharge threshold (VRCH=120mV). Alternatively, you can force recharge by toggle the CE bit, HiZ bit or /CD pin.  If a load transient on SYS causes a supplement event (battery must provide some of SYS load current), charge is also restarted.  Removing/replacing either IN/USB or the battery also restarts charge.

    If HZ_MODE= 1 or /CD pin = high disables the buck converter and places the chip in the lowest quiescent current state, with BAT tied to SYS through the BATFET (i.e., the battery provides the system load).

    Regards,

    Jeff
