The Texas Instruments BQ2004SNTR is a versatile battery charger IC capable of fast charging and conditioning nickel cadmium (NiCd) or nickel-metal hydride (NiMH) batteries. It supports multi-chemistry applications and can handle 1 to 4 series cells.
Key electrical specifications include a maximum charge current of 2A, an input voltage range of 4.5V to 5.5V, and a maximum battery charge voltage of 5.5V. The device features hysteretic PWM switch-mode current regulation and offers termination by voltage, maximum voltage, maximum temperature, and maximum time. It also includes optional top-off charge and pulsed current maintenance charging.
Designed for ease of integration, the BQ2004SNTR can be used in stand-alone chargers or system-integrated solutions. It features configurable LED outputs for battery and charge status indication and a logic-level controlled low-power mode with less than 5µA standby current.
The IC is housed in a 16-SOIC package and is designed for surface mount applications. Its operating temperature range is -20°C to 70°C.
