General Description

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, constantcurrent, or pulsed-current charging.

The regulator frequency is set by an external capacitor for design flexibility.

Key Features

  • Conforms to battery manufacturers' charge recommendations for cyclic and float charge.
  • Pin-selectable charge algorithms - Two-Step Voltage with temperature-compensated constant-voltage maintenance - Two-Step Current with constant-rate pulsed current maintenance - Pulsed Current: hysteretic, on-demand pulsed current.
  • Pin-selectable charge termination by maximum voltage,∆2V, minimum current, and maximum time.
  • Pre-charge qualification detects shorted, opened, or.
