Product details

Single-cell Li-Ion charger with USB input and integrated protection

It accepts a USB input up to 10.2 V and delivers a programmable constant charge current up to 500 mA to a 4.2 V battery pack. The charger integrates fault protection against over-temperature, over-voltage, reverse current, and short circuit, reducing external component count. The programmable current and timer features let the designer tailor the charge profile to the cell capacity.

500 mA charge current — sizing the charge time

The 500 mA maximum charge current sets the charge time for a given cell capacity.

Frequently asked questions

What is the difference between BQ24232RGTT and BQ24232RGT?

The BQ24232RGTT and BQ24232RGT share the same base product number BQ24232 and the same 16-VQFN package. The difference is in the packaging and tape/reel options. The RGTT suffix typically indicates Tape & Reel packaging, while the RGT suffix may indicate a different reel quantity or tube/tray option. Both are electrically identical.

What are the specifications of BQ24232RGTT?

The BQ24232RGTT is a single-cell Li-Ion battery charger IC with a USB interface. It charges at a programmable constant current up to 500 mA to a 4.2 V battery pack. Supply voltage range is up to 10.2 V. It includes fault protection for over-temperature, over-voltage, reverse current, and short circuit. Operating junction temperature range is -40°C to 125°C. Package is 16-VQFN (3x3 mm) with exposed pad.

Is BQ24232RGTT compatible with BQ24232?

Yes, the BQ24232RGTT is a specific variant of the base product BQ24232. The base number BQ24232 covers the same charger IC in different package and tape options. The RGTT suffix specifies the 16-VQFN package in Tape & Reel or Cut Tape. The electrical specifications and pinout are identical across the BQ24232 family variants.
