This procedure prevents high-current charging of cells that are possibly damaged or reversed. If the battery voltage is less than the low-voltage threshold, the bq2031 provides trickle-currentĬharging until the voltage rises into the allowed range or an internal timer runs out and places the in a Fault condition. For safety, charging is inhibited until the battery voltage is within configured limits. A charge cycle begins when power is applied or the battery is replaced. The switch-mode design keeps power dissipation to a minimum for high charge current applications. The regulator frequency is set by an external capacitor for design flexibility. A flexible pulse-width modulation regulator allows the bq2031 to control constant-voltage, constantcurrent, or pulsed-current charging. The bq2031 Lead-Acid Fast Charge IC is designed to optimize charging of lead-acid chemistry batteries. Two-Step Voltage with temperature-compensated constant-voltage maintenance Two-Step Current with constant-rate pulsed current maintenance Pulsed Current: hysteretic, on-demand pulsed currentĭirect LED control outputs display charge status and fault conditions Ideal for high-efficiency switch-mode power conversion Configurable for linear or gated current use | DocĭV2031S2: Evaluation Module for Lead Acid, switchmode BQ2031Ĭonforms to battery manufacturers' charge recommendations for cyclic and float charge Pin-selectable charge algorithms This application note discusses the operation of the bq2031 and describes a switch-mode buck regulator charger using the bq2031. The bq2031 fast-charge IC has two primary functions: lead-acid battery charge control and switch-mode power conversion control.
