Charger with programmable input current and charge current?

Anthony Knighton

Other Parts Discussed in Thread: BQ2000

Which Li-Ion battery (1-cell) chargers have input current limiting (programmable with a resistor)? I'd actually like to have both input current and charge limiting resistors. There doesn't seem to be a device parameter on the table that I can choose that will show me which parts have it.

Thanks

Anthony,

What sort of application is this for? Our chargers are grouped by application type: linear, switchmode, host-controlled, stand-alone, etc. What is your input source? What charge rate do you want? Do you have a host (uC) in your system?

The new bq124180/5 allow either the inpur or charge current to be set by the host via I2C. A charger with an I2C interface would likely do what you want.

The bq2000 is an older, stand-alone charger that would not likely be the right fit for your application.

Anthony,

Were you able to find a part that would work for your application? Just let me know if you need any additional information.
