BQ25896: BQ25896 with 3series NiMH battery

Hi Star,

When charging at <0.5C, it is generally acceptable to terminate NiMH using a safety timer only.  The BQ25896 can do this but the 4.2V default VBATREG and 2A charge current will need to be changed via I2C. 

When charging at >0.5C , it is highly recommended for long battery life to terminate NiMH with either very precise dV/dt or dTemp/dt termination method, which the BQ25896 cannot do, even with host software and its 7-bit ADC.  A more precise ADC, controlled by the host, would be necessary to determine when to terminate.

 Regards,

Jeff
