Multi-chemistry charge controller in a compact 8-TSSOP
The Texas Instruments BQ24400PW is a multi-chemistry battery charge controller IC designed for applications requiring flexible charging algorithms across different battery types — lead-acid, Li-ion, NiMH, NiCd, and others. It integrates programmable timer and voltage features to set the charge profile, making it suitable for portable instruments, backup power systems, and general-purpose battery management where a single charger must handle multiple chemistries. The device operates from a 6V maximum supply and is specified over a -20°C to 70°C ambient temperature range, covering most indoor and commercial equipment environments.
Active lifecycle — stable for BOM planning
The part is also ROHS3 compliant, which aligns with global environmental regulations and avoids the need for exemption management.
Package and mounting — surface-mount 8-TSSOP
The device is supplied in an 8-TSSOP package (0.173", 4.40mm width) with surface-mount mounting, and the supplier device package is also 8-TSSOP.
