The bq24600 is a highly integrated Li-ion or Li-polymer switch-mode battery-charge
controller. It offers a constant-frequency synchronous PWM controller with high-accuracy charge
current and voltage regulation, charge preconditioning, termination, and charge status monitoring,
The bq24600 charges the battery in three phases: preconditioning, constant current, and
constant voltage. Charge is terminated when the current reaches a minimum level. An internal charge
timer provides a safety backup. The bq24600 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.
