Product details

Multi-chemistry charger for 2-4 cell packs

The Texas Instruments BQ24740RHDTG4 is a multi-chemistry battery charger IC designed for 2 to 4 series cells, supporting a maximum charge current of 10A and a battery pack voltage up to 18V. It uses constant-current programmable charging with over-voltage fault protection, making it suitable for Li-ion, Li-Polymer, and other chemistries in portable devices, power tools, and industrial equipment.

10A charge current — thermal and footprint considerations

The 10A max charge current places this part in the high-power tier for a battery charger IC in a 28-VFQFN Exposed Pad package.

Obsolete — sourcing through independent distribution

The BQ24740RHDTG4 carries an obsolete lifecycle status.
