产品概述
The bq24630 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, adapter
current regulation, and charge status monitoring.The bq24630 charges the battery in three phases: preconditioning, constant current, and
constant voltage. Charge is terminated when the current reaches a minimum user-selectable level. A
programmable charge timer provides a safety backup. The bq24630 automatically restarts the charge
cycle if the battery voltage falls below an internal threshold and enters a low quiescent current
sleep mode when the input voltage falls below the battery voltage.
