BQ24401PW Description

Short technical summary and product information.

The BQ24401PW from Texas Instruments is a versatile switch-mode buck battery charger IC designed for NiCd and NiMH battery packs. It supports single to four-cell configurations and offers a maximum charge current of 2A.

 

This IC provides advanced charge termination criteria including rate of temperature rise (ΔT/Δt), maximum temperature, and maximum charge time. It also features BAT temperature thermistor monitoring for hot/cold profiles, pre-charge qualification for detecting faulty cells, and selectable top-off mode for maximum NiMH capacity. Programmable trickle-charge mode is available for reviving deeply discharged batteries and for post-charge maintenance.

 

Designed for efficient and simple charger designs, the BQ24401PW operates with an input voltage range of 4V to 6V (absolute max 7V) and a battery charge voltage range of 0.95V to 6V. The control interface is standalone and RC-settable. The device is housed in an 8-TSSOP package suitable for surface mounting.

 

Applications include nickel chargers and high-power, multi-cell chargers. The BQ24401PW is ideal for systems requiring safe and efficient management of fast charging for nickel-based battery chemistries.
