Top Features

Packaging

  • Internal and external PWM dimming options
  • Two ADIM pins for LED binning, NTC feedback, or hybrid analog/PWM dimming
  • Adjustable integrated LED current derating for elevated VIN
  • Integrated LED current derating for elevated IC junction temperature
  • MINOUT signal for trimming pre-regulator to minimize power loss
  • Selectable LED current slew rate limit during PWM dimming
  • Extensive fault detection and protection
  • Current sense voltage options of 500mV (A80804) for better BCI immunity or 200mV (A80804-1) for lower power dissipation in the sense resistors

Typical Applications

  • Automotive Medium-Power LED Lighting Systems
  • Fog Lights, Backup Lights, Daytime Running Lights, Position Lights, Sequential Lights
