BQ2003S Description

Short technical summary and product information.

The Texas Instruments BQ2003S is a versatile switch-mode battery charger IC capable of fast charging and conditioning nickel cadmium (NiCd) or nickel-metal hydride (NiMH) batteries. It supports charging for 1 to 4 series cells and offers a maximum charge current of 2A. The device operates with an input voltage range of 4.5V to 5.5V and features a battery charge voltage range of 0V to 5.5V.

 

Key features include battery temperature thermistor monitoring for hot and cold profiles, ensuring safe and efficient charging. The control topology is switch-mode buck, and it utilizes a hysteretic PWM control for high-efficiency power conversion. The BQ2003S provides standalone control with RC-settable options and direct LED outputs for battery and charge status indication.

 

Designed for integration into systems or use as a stand-alone charger, this IC facilitates pre-charge qualification based on temperature and voltage. Fast-charge termination is managed by V, maximum voltage, maximum temperature, and maximum time. An optional top-off charge feature is also available.

 

The BQ2003S is supplied in a 16-SOIC package, suitable for surface mount applications. Its operating temperature range is from -40°C to 85°C.
