The charge time is adjustable by setting the charge current limit from to A maximum. 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 A8731 features very low supply current draw-typically µA in shutdown mode and 10 µA in standby mode. The A8731 has a flash dual trigger IGBT driver. The A8731 is available in a 10-contact 3 mm x 3 mm TDFN/MLP package with a nominal overall package height, and an exposed pad for enhanced thermal performance.
