Ultra Small Mobile Phone Xenon Photoflash Capacitor Charger With IGBT Driver

The Allegro® A8735 is a Xenon photoflash charger IC designed to meet the needs of ultra low power, small form factor cameras, particularly camera phones. By using primary-side voltage sensing, the need for a secondary-side resistive voltage divider is eliminated. This has the additional benefit of reducing leakage currents on the secondary side of the transformer. To extend battery life, the A8735 features very low supply current draw (0.5 µA max in shutdown mode). The IGBT driver also has internal Gate resistors for minimum external component count. The charge and trigger voltage Logic thresholds are set at 1 VHI(min) to support applications implementing low-voltage control Logic By Allegro MicroSystems, Inc.
