The A8519KLPTR-T-1 is a 20-pin TSSOP with exposed thermal pad automotive LED driver for driving four strings of LEDs up to 100 mA each, with a boost converter supporting input voltages from 4.5 V to 40 V and output voltages up to 40 V. It is AEC-Q100 qualified, operates from -40°C to 125°C ambient temperature, and uses a 150 mV hysteresis window to reduce output voltage ripple during PWM dimming compared to the A8519 variant. It supports PWM dimming with a contrast ratio of 10,000:1 and includes protection against open/shorted LEDs, overvoltage, and overtemperature.
The A8519-1 offers a versatile solution for driving multiple LED strings, with four integrated current sinks, a boost converter, and PWM dimming for precise brightness control. The A8519-1 provides reduced output voltage ripple for enhanced dimming performance.
