BQ2031 Datasheet (Benchmarq) - Lead-Acid Fast-Charge

BQ2031, Lead-Acid Fast-Charge

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 d
