●The BQ24650EVM Evaluation Module assists users in evaluating the bq24650 synchronous battery charger. The bq24650 is a highly integrated switch-mode battery charge controller. It 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 maintains the panel at maximum power output. The bq24650 offers a constant-frequency, synchronous PWM controller with high-accuracy current and voltage regulation, charge preconditioning, charge termination and charge status monitoring. The BQ24650EVM is also called the HPA639 A. The manual includes the bq24650EVM bill of materials, board layout and schematic. The user"s guide SLUU444 describes the features and operation of the bq24650EVM.
● Synchronous switch-mode battery charge controller for solar power
● Resistor-programmable up to 26Vbattery voltage
● Input operating range: 5V to 28V
● LED indication for charge status
● Test points for key signals available for testing purposes; easy probe hook-up
● Jumpers available; easy-to-change setting
● BQ24650 charges the battery in three phases: preconditioning, constant current and constant voltage
● BQ24650 offers a constant-frequency, synchronous PWM controller with high-accuracy regulation
● BQ24650 offers voltage regulation, charge preconditioning, charge termination and status monitoring
