The BQ24401DR from Texas Instruments is a versatile switch-mode battery charger IC designed for NiCd and NiMH battery applications. It supports single to multi-cell configurations, specifically 1 to 4 series cells.
Key electrical specifications include a minimum input voltage of 4V and a maximum of 6V, with an absolute maximum rating of 7V. The device can deliver a maximum charge current of 2A. It features a switch-mode buck control topology and operates within a temperature range of -20°C to 70°C. The control interface is standalone and RC-settable.
This IC offers advanced charge termination criteria, including rate of temperature rise (ΔT/Δt), maximum temperature, and maximum charge time. Additional features include battery temperature thermistor monitoring, pre-charge qualification for detecting faulty cells, selectable top-off mode for maximum NiMH capacity, and programmable trickle-charge mode for reviving deeply discharged batteries. It also includes built-in battery removal and insertion detection, and a sleep mode for low power consumption.
The BQ24401DR is available in an 8-SOIC package with surface mount mounting type. Its robust design makes it suitable for high-power, multi-cell nickel charger applications.
