Switch-mode Lead-acid Battery Charger With User-selectable Charge Algorithms

  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. 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-current
