BQ2004H Description

Short technical summary and product information.

The Texas Instruments BQ2004H is a monolithic CMOS device providing comprehensive fast-charge control for Nickel Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) batteries. It integrates high-speed switching power control circuitry and closed-loop current control, making it suitable for both stand-alone and system-integrated chargers.

Key features include hysteretic PWM switch-mode current regulation or gated control of an external regulator. The device supports pre-charge qualification of temperature and voltage, and offers configurable LED outputs for battery and charge status indication. Fast-charge termination can be achieved through various methods including temperature rise, peak voltage detection, negative delta voltage, maximum voltage, maximum temperature, and maximum time.

This IC operates within a 4.5V to 5.5V input voltage range and supports a maximum charge current of 2A. It is available in SOIC (D) 16 and PDIP (N) 16 packages, with an operating temperature range of -20°C to 70°C. The BQ2004H also includes a logic-level controlled low-power mode with less than 5µA standby current.

Note: This product is in the process of being discontinued. New designs should consider an alternate product.
