A6262

FEATURES AND BENEFITS ▪ AEC-Q100 qualified ▪ Total LED drive current up to 400 mA ▪ Current shared equally up to 100 mA by 4 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 ▪ Current set by reference resistor ▪ Automotive temperature range APPLICATIONS: ▪ Dome light, map light, space lighting, mood lighting PACKAGES: 10-pin MSOP with exposed thermal pad (suffix LY) 16-pin TSSOP with exposed thermal pad (suffix LP) A6262 Automotive LED Array Driver DESCRIPTION TheA6262 is a linear, programmable current regulator providing up to 100 mA from each of four 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 the use of ballast resistors. Driving LEDs with constant current ensures safe operation with maximum possible light output. Output control is provided by an enable input, giving direct control for PWM applications, and by a debounced switch input, proving an on/off toggle action. Optimum performance is achieved driving 1 to 3 LEDs in each string: up to 4 strings at 100 mA each. Outputs can be connected in parallel or left unused as required. Short detection is provided to protect the LEDs and the A6262 during a short-to-ground at any LED output pin. The output will automaticall...
