描述: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, constant-current, 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.
A charge cycle begins when power is applied or the battery is replaced. For safety, charging is inhibited until the battery voltage is within configured limits. If the battery voltage is less than the low-voltage threshold, the bq2031 provides trickle-currentcharging until the voltage rises into the allowed range or an internal timer runs out and places the bq2031 in a Fault condition. This procedure prevents high-current charging of cells that are possibly damaged or reversed. Charging is inhibited anytime the temperature of the battery is outside the configurable, allowed range. All voltage thresholds are temperature-compensated.
The bq2031 terminates fast (bulk) charging based on the following:
產(chǎn)品特性
Conforms to battery manufacturers' charge recommendations for cyclic and float charge
Pin-selectable charge algorithms
Pin-selectable charge termination by maximum voltage, 2V, minimum current, and maximum time
Pre-charge qualification detects shorted, opened, or damaged cells and conditions battery
Charging continuously qualified by temperature and voltage limits
Internal temperature-compensated voltage reference
Pulse-width modulation control
Direct LED control outputs display charge status and fault conditions
