Description
The A6261 is a linear, programmable current regulator providing
up to 100 mA from each of four outputs (LP and LY) 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. The A6261 in the LJ package offers two outputs with
100 mA and 200 mA maximum output current.
Output control is provided by an enable input, giving direct
control for PWM applications. Outputs can be connected in
parallel or left unused as required.
Short detection is provided to protect the LEDs and the A6261
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 an 8-pin SOICN (suffix LJ), a 10-pin
MSOP (LY), and a 16-pin TSSOP (LP), all with exposed pad
for enhanced thermal dissipation. They are lead (Pb) free, with
100% matte tin leadframe plating.
