BQ2954SNTR Description

Short technical summary and product information.

The BQ2954SNTR from Texas Instruments is a versatile Li-ion charge controller IC that utilizes a flexible pulse-width modulation regulator for precise voltage and current control during charging. Its switch-mode design minimizes power dissipation, making it an efficient solution for battery management.

 

This IC supports 1 to 4 series cells and offers a maximum charge current of 2A. It operates with an input voltage range of 4.5V to 5.5V, with an absolute maximum input voltage of 7V. Key features include battery temperature monitoring via a thermistor, programmable current sensing, and safety backup termination. The device also provides direct LED control outputs for charge status and fault indication.

 

The BQ2954SNTR is housed in a 16-SOIC package and is designed for surface mount applications. It employs a two-phase charging process: a constant-current phase to replenish approximately 70% of battery capacity, followed by a voltage-regulation phase to complete the charge. Safety features include precharge qualification to detect damaged cells and continuous qualification based on temperature and voltage limits.
