BQ25756E: CC and CV alone in Standalone Mode

Abishek V
Prodigy 175 points
Part Number: BQ25756E

Tool/software:

I need to just charge the Battery with Constant current (CC) and Constant voltage (CV) with dynamic programmable Constant current up to 10A

Please confirm whether we can use BQ25756E in just CC and CV in standalone mode without use of I2C Interface and no additional charging modes

Also Please let know how to dynamically program Constant current (CC) up to 10A

    Hi,

    The BQ25756E can do CC and CV in standalone. You will have to be able to change the resistance on the ICHG pin to do this. This would likely mean some sort of digital potentiometer. You will not be able to change the precharge functionality, however.

    Best regards,
