Product details

Multi-chemistry charger for 2-4 cell packs

The Texas Instruments BQ24705RGER is a multi-chemistry battery charger controller designed for 2 to 4 series-cell battery packs, supporting charge currents up to 8 A and a maximum battery pack voltage of 18 V.

Charge current and voltage limits

The programmable constant-current charging allows the designer to set the charge rate via external components, with an 8 A maximum that supports fast charging of larger-capacity packs. The 18 V maximum battery pack voltage accommodates 4-cell lithium-ion packs (typical 4.2 V/cell = 16.8 V nominal) with margin for cell balancing and termination voltage.

Frequently asked questions

What is the maximum battery pack voltage for the BQ24705RGER?

The maximum battery pack voltage is 18 V, which supports 4-cell lithium-ion packs (16.8 V nominal) with headroom for termination voltage.

Can the BQ24705RGER charge 4-cell lithium-ion batteries?

Yes, it supports 2 to 4 series cells and the 18 V maximum pack voltage covers 4-cell Li-ion packs up to their typical 4.2 V/cell termination voltage.
