Product details

What this charger IC handles — and where it hits its ceiling

The BQ24617RGET is a Li-Ion/Polymer synchronous buck charger that handles 1 to 5 series cells with a programmable constant-current charge up to 10 A. The 24 V max input covers 4S and 5S packs with headroom for inductor and input cap derating. Integrated fault protection covers over-voltage, over-current, short-circuit, and over-temperature — no external supervisor IC needed for basic safeguard.

Package, mounting, and production status

Surface-mount 24-VFQFN Exposed Pad, supplier package 24-VQFN (4x4 mm). TI continues to support this part for new designs. ROHS3 compliant. The base product number is BQ24617.

Frequently asked questions

Can BQ24617RGET charge a 4S LiPo battery?

Yes — it supports 1 to 5 series cells. A 4S LiPo pack (nominal 14.8 V, full 16.8 V) is well within the 24 V input ceiling. The charge current is programmable up to 10 A, so you can set a C-rate appropriate for your pack capacity.

How do I program the charge current on BQ24617RGET?

A single resistor from the ISET pin to GND sets the constant-current charge level. The resistor value is calculated per the formula in the datasheet to achieve the desired current up to the 10 A maximum. No I2C or PWM programming — it is a pure analog pin.
