HT45F5Q-2 Description
For AC/DC charger applications, the Charger ASSP Flash MCU HT45F5Q-2 includes a battery charger management module, which can be used for the constant voltage and constant current closed loop charging control. The device therefore reduces the need for the usually required external TL431 ponent, operational amplifier and resistance analogic D/A Converter in traditional battery charging circuits. Therefore the...
