BQ2003PN Description

Short technical summary and product information.

The BQ2003PN from Texas Instruments is a versatile switch-mode battery charger IC capable of fast charging and conditioning nickel-cadmium or nickel-metal hydride batteries. It supports 1 to 4 series cells and offers a maximum charge current of 2A. The device operates within an input voltage range of 4.5V to 5.5V, with an absolute maximum input voltage of 7V. Key features include battery temperature thermistor monitoring for hot and cold profiles, and direct LED outputs for battery and charge status indication.

 

This IC integrates comprehensive fast charge control functions with high-speed switching power control circuitry. It utilizes a hysteretic PWM switch-mode current regulation or gated control of an external regulator. The BQ2003PN is easily integrated into systems or used as a stand-alone charger. It provides pre-charge qualification based on temperature and voltage, and fast-charge termination by V, maximum voltage, maximum temperature, and maximum time. An optional top-off charge function is also available.

 

The BQ2003PN is available in a 16-PDIP package and is suitable for through-hole mounting. Its operating temperature range is from -40°C to 85°C. The control interface is standalone and RC-settable, offering flexibility in system design.
