The BQ2005STR from Texas Instruments is a monolithic CMOS device providing comprehensive fast-charge control for sequential management in dual battery pack applications. This switch-mode charger is suitable for NiCd and NiMH battery chemistries, supporting 1 to 4 series cells.
Key features include hysteretic PWM switch-mode current regulation, pre-charge qualification based on temperature and voltage, and direct LED outputs for battery and charge status indication. Fast-charge termination is managed by voltage, maximum voltage, maximum temperature, and maximum time. The device also supports optional top-off and pulse-trickle charging, along with switch-activated discharge-before-charge functionality.
Operating within a temperature range of -20°C to 70°C, the BQ2005STR requires an input voltage between 4.5V and 5.5V, with an absolute maximum of 7V. It is available in a 20-SOIC package suitable for surface mounting.
This IC is ideal for cost-effective, stand-alone or system-integrated chargers for batteries requiring sequential charging management.
