BQ24600RVAT

Зарядное устройство для 6-элементной литий-ионной, Li-Pol батареи, 28В вход, 10A зарядка, VQFN-16.

The BQ24600RVAT is a stand-alone synchronous switch-mode highly integrated Li-ion/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 such as 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 charge controller 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.
