Product Description

The BQ24650RVAT is a synchronous switch-mode integrated Battery-charge Controller for solar power with maximum power point tracking provides input voltage regulation, which reduces charge current when input voltage falls below a programmed level. When the input is powered by a solar panel, the input regulation loop lowers the charge current so that the solar panel can provide maximum power output. The BQ24650 offers a constant-frequency synchronous PWM controller with high accuracy current and voltage regulation. The charge controller charges the battery in three phases such as pre-conditioning, constant current and constant voltage. Charge is terminated when the current reaches 1/10 of the fast charge rate. The pre-charge timer is fixed at 30 minutes. 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.
