Part Number: BQ2031
Function: Lead-Acid Fast-Charge IC
Package: DIP, SOIC 16 Pin Type
Manufacturer: Texas Instruments
The bq2031 Lead-Acid Fast Charge IC is designed to optimize charging of lead-acid chemistry batteries. A flexible pulse-width modulation regulator allows the bq2031 to control constant-voltage, onstantcurrent, or pulsed-current charging.
The regulator frequency is set by an external capacitor for design flexibility. The switch-mode design keeps power dissipation to a minimum for high charge current applications.
1. Pin-selectable charge termination by maximum voltage,Δ2V, minimum
current, and maximum time
2. Pre-charge qualification detects shorted, opened, or damaged cells and conditions battery
3. Charging continuously qualified by temperature and voltage limits
4. Internal temperature-compensated voltage reference
