Product details

Single-cell Li-Ion linear charger with 500 mA ceiling

The BQ24203DGNRG4 is a Texas Instruments linear charger IC designed for single-cell Lithium Ion and Lithium Polymer battery packs, delivering a constant-current charge up to 500 mA with a regulated 4.1V battery pack voltage target. The device integrates over-temperature and short-circuit fault protection, and offers programmable charge current and timer settings via external components.

For a BOM that requires this charger IC, the procurement path is through verified independent distributors who can source new-old-stock or qualified surplus lots. The 8-HVSSOP package and 500 mA charge-current spec are the critical matching points when evaluating any alternate or replacement part.

Package and footprint — 8-HVSSOP with exposed pad

The device is supplied in an 8-HVSSOP package (3.00 mm width, exposed pad), surface-mount, on Tape & Reel. The exposed thermal pad requires a solderable ground plane on the PCB for adequate heat dissipation during charging.

Frequently asked questions

What is the maximum charge current of BQ24203DGNRG4?

The maximum charge current is 500 mA, delivered as a constant-current charge for single-cell Li-Ion or Li-Polymer batteries. The charge current is programmable via an external resistor.

Does BQ24203DGNRG4 have battery pack voltage protection?

Yes, the device regulates the battery pack voltage to 4.1V and includes over-temperature and short-circuit fault protection to safeguard the battery and the charging circuit.
