The HT45F5Q-3 is a battery charger MCU integrated with two groups of OPAs and a 12-bit/14-bit D/A converter that allows the charger to control multiple groups of constant currents and constant voltages. Holtek provides the HT45F5Q-x series charger development workshop. You can set parameters on the workshop and then generate the program codes.
NOTE
