A6261KLPTR-T [Allegro]

The A6261 is a linear current regulator designed to provide drive current and protection for parallel strings of series-connected high brightness LEDs. It offers up to four matched programmable current outputs at up to 100 mA (LP and LY packages) or two outputs at up to 200 mA per channel (LJ package). The regulated LED current, accurate to 5%, is set by a single reference resistor. Current matching in each string is better than 10% without ballast resistors. The device features AEC-Q100 qualification, 6 to 50 V supply range, low dropout voltage, LED output short-to-ground and thermal protection, disable on open LED detection, enable input for PWM control, and current slew rate limit during PWM. It operates in automotive temperature range (K grade: –40°C to 150°C).
