The BQ2003PN-N 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 provides a maximum charge current of 2A.
Key electrical specifications include an input voltage range of 4.5V to 5.5V, with an absolute maximum input voltage of 7V. The device features a switch-mode buck control topology and supports battery charge voltages from 0V to 5.5V. The control interface is standalone and RC-settleable.
This IC is housed in a 16-PDIP package and is designed for through-hole mounting. It operates within a temperature range of -40°C to 85°C. The BQ2003PN-N integrates comprehensive fast charge control functions with high-speed switching power control circuitry on a monolithic CMOS device, making it suitable for cost-effective stand-alone and system-integrated chargers.
Features include battery temperature thermistor monitoring, pre-charge qualification, and direct LED outputs for battery and charge status. Fast-charge termination is supported by V, maximum voltage, maximum temperature, and maximum time. An optional top-off charge is also available. Note that this product is in the process of being discontinued, and new designs should consider an alternate product like the BQ25172.
