A6269 Automotive LED Array Driver

TheA6269 is a linear, programmable current regulator providing up to 200 mA from each of two outputs to drive arrays of high brightness LEDs. The regulated LED current from each output, accurate to 5%, is set by a single reference resistor. Current matching in each string is better than 10% without .

A6269 Features

* ▪ AEC-Q100 qualified ▪ Total LED drive current up to 400 mA ▪ Current shared equally up to 200 mA by 2 strings ▪ 6 to 50 V supply ▪ Low dropout voltage ▪ LED output short-to-ground and thermal protection ▪ On/off toggle switch input ▪ Enable input for PWM control ▪ Current slew rate limit during PWM
