Description
The A6264 is a linear, programmable current regulator providing
up to 100 mA from each of four outputs to drive arrays of high
brightness LEDs. The LED current can be switched between
high current and low current for stop/tail applications. The
two LED current levels from each output, accurate to 5%,
are set by two reference resistors. 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.
Optimum performance is achieved when driving 4 strings with
1 to 3 LEDs in each string, at a total current of up to 100 mA
in each string. Outputs can be connected in parallel or left
unused as required.
Short detection is provided to protect the LEDs and the A6264
during a short-to-ground at any LED output pin. An open LED
in any of the strings disables all outputs but can be overridden.
Shorted LED output pins or open LEDs are indicated by a
fault flag.
A temperature monitor is included to reduce the LED drive
current if the chip temperature exceeds a thermal threshold.
The device packages are a 10-pin MSOP (LY) and a 16-pin
TSSOP (LP), both with exposed pad for enhanced thermal
dissipation. They are lead (Pb) free, with 100% matte tin
leadframe plating.
