Product details

Charger IC for 2-4 cell packs — 8 A ceiling

It accepts a supply voltage up to 24 V and includes over-voltage fault protection on the output.

Charge current and thermal budget

The constant-current programming is set with an external resistor; the datasheet gives the formula for the desired current.

The multi-chemistry support covers Li-ion, Li-Po, and LiFePO4 cells, so the same BOM can serve different pack chemistries by adjusting the charge voltage threshold.

Housed in a 24-VFQFN with exposed pad (4x4 mm body), the part is surface-mount only.

Frequently asked questions

What is the maximum charge current of BQ24705RGET?

The BQ24705RGET supports a programmable constant charge current up to 8 A max, set by an external resistor.

What battery chemistries does BQ24705RGET support?

It is a multi-chemistry charger, compatible with Li-ion, Li-Po, LiFePO4, and other chemistries — the charge voltage is set by the external resistor divider.
