[Battery charger] Request for recommending battery charger IC(1cell)

Other Parts Discussed in Thread: BQ24045, BQ25616

Hi, TI support team

Please recommend a product that meets the conditions below.

- Charging Current : 2~3A

- Charging Voltage : 4.35V

- Charging current setting according to input source: 500mA (when connected to PC)

Basically, we are looking for a product that satisfies the functions of the BQ24045 product and supports charging current of 2~3A.

Looking at the table below, the functions of ISET, ISET2, and CHG pins are required.

If there are applicable parts, please recommend them.

Thanks.

Regards,

MJ

  • Hi MJ,

    The closest buck switch mode charger with integrated FET and NVDC (i.e. SYS pin) is BQ25616.  It is a 3A standalone charger with ICHG pin providing ISET function, VSET allowing for 4.35V setting and D+/D- setting input current limit (with max clamped by ILIM pin resistor).  It does not have /PG pin but REGN can be used to identify power is connected.

    Regards,

    Jeff
