Description
The A6262 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 automatically resume the regulated current when the short
is removed.
A temperature monitor is included to reduce the LED drive
current if the chip temperature exceeds an adjustable thermal
threshold.
The device packages are a 10-pin MSOP (suffix 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.
