产品概述
The bq24620 device is a highly integrated lithium phosphate switched-mode battery charge
controller. The device offers a constant-frequency synchronous switching PWM controller with
high-accuracy charge current and voltage regulation, charge preconditioning, termination, and
charge status monitoring.The bq24620 charges the battery in three phases: preconditioning, constant current, and
constant voltage.
