Here’s new from Allegro MicroSystems, they just released the A6261 Protected LED Array Driver. It is a programmable current regulator that uses linear operation and supplies up to 100mA from each of four outputs (PL and LY) to drive arrays of high brightness LEDs. To ensure safe operation with maximum possible light output this driver would drive the LEDs with constant current. It has 2 outputs with 100mA and 200 mA.
It has an output control, which enables a direct control for PWM applications, short detection is also provided to protect LEDs and the A6261 whenever a short-to-ground happen at any LED output pin. There is also a temperature monitor. On the package are 8-pin SOICN, 10-pin MSOP and 16-pin TSSOP, all with exposed pad for enhanced thermal dissipation. Lead free with 100% matte tin leadframe plating.
With the following Features & Benefits:
