Hi TI-team

The following charging current is described in the data sheet.

Can a NiMH battery be charged with a smaller current?

IOCHARGE = 150mA-2000mA

IOPRECHG = 15mA-200mA

Hi Hayashi-san,

NIMH batteries can be fast charged but require either dT/dt or dV/dt termination. Or, they can be slow charged with timer only termination. The BQ24105-Q1 has not tested with lower than 150mA charge current and 15mA precharge current. The tolerance at lower currents cannot be warrantied and will be wider.

Regards,

Jeff
