This solution is an integrated pure digital power control and charging management solution with a single main control chip. Compared to traditional analog power control, it integrates operational amplifiers, comparators, and MOS drivers, greatly saving on external circuits and providing flexible parameter configurations for faster user development. Users only need to refer to the schematics provided by the official Yijin Microelectronics and can achieve diversified charging management without the involvement of software engineers.

Half-bridge three-stage charger solution based on EG1165, EG4320, and EG1516 chips, with an input voltage of AC 220V±20%, capable of providing constant current charging of 10.0A±0.1A, constant voltage DC 87V±0.5V, and float charging DC 82.5V±0.5V for a 72V lead-acid battery, equipped with various protection and control functions, featuring LED charge indicator lights and a 12V 0.2A fan interface, achieving control of each charging stage through specific circuit principles to meet the charging needs of electric vehicles.
