The BQ24401PWR from Texas Instruments is a versatile switch-mode battery charger IC designed for nickel cadmium (NiCd) and nickel metal-hydride (NiMH) battery packs. It is suitable for both single and multi-cell configurations, offering efficient charging management.
This IC provides several advanced charge termination criteria, including rate of temperature rise (ΔT/Δt), maximum temperature, and maximum charge time, ensuring safe and optimal charging. It also features battery temperature thermistor monitoring for hot/cold profile management, pre-charge qualification for detecting cell issues, and selectable top-off mode for maximizing NiMH capacity. Programmable trickle-charge mode is available for reviving deeply discharged batteries and for post-charge maintenance.
The BQ24401PWR operates with an input voltage range of 4V to 6V (absolute max 7V) and supports battery charge voltages from 0.95V to 6V. It features a standalone control interface that is RC-settable and a switch-mode buck control topology. The device is available in an 8-TSSOP package and operates within a temperature range of -20°C to 70°C.
Key features include built-in battery removal and insertion detection, as well as a sleep mode for low power consumption. This makes the BQ24401PWR ideal for high-power, multi-cell nickel charger applications requiring safe and efficient fast-charge management.
