Battery Charger Circuit for NiMH with Status Indicator

An application note for an intelligent trickle battery charger circuit for NiMH batteries, using an 8-bit microcontroller.

This design overcomes the disadvantages of trickle chargers. These types of charges, in contrast to fast chargers, are more economical. In this design, a microcontroller provides charge status and detect faults.

This battery charger circuit allows simultaneous charging of up to four NiMH batteries. The circuit for the battery charger is shown here:
