Product details

Multi-chemistry charger controller in 8-TSSOP

The Texas Instruments BQ24401PWG4 is a multi-chemistry battery charger controller designed for charging a range of battery types — NiCd, NiMH, Li-Ion, and lead-acid — without requiring a separate chemistry-specific IC. It integrates a programmable timer for charge termination, making it suitable for standalone charger designs in consumer and industrial equipment where the battery chemistry may vary across product variants.

Supply rail and temperature envelope

The device operates from a maximum supply voltage of 6V, which sets the input rail requirement for the charger circuit — a regulated 5V rail or a 6V wall adapter is typical. The operating temperature range of -20°C to 70°C covers most indoor and sheltered outdoor applications, including portable instruments, backup power systems, and battery-powered tools that are not exposed to extreme cold or engine-bay heat.

Package and mounting

The 8-TSSOP footprint is shared across the BQ24401 family, so a board layout for one member accepts the others.

Frequently asked questions

What is the difference between BQ24401PWG4 and BQ24401PW?

The BQ24401PWG4 is the Tube-shipped variant of the BQ24401PW. The PW suffix indicates the 8-TSSOP package; the G4 suffix denotes the Tube shipping medium. The die and electrical specifications are identical — the only difference is the shipping format.
