1 General Description
The AS1101/AS1102/AS1103/AS1104 are LED drivers
designed to match current source bias for any color
LED, including white and blue. The devices can drive up
to 4 high-current LEDs, and the LED current is program-
mable using an external resistor (R
SET
).
The AS1101 LED currents are 460 x I
SET
(per LED, typ)
at an LED cathode voltage (V
SAT
) of 150mV and 650 x
I
SET
(typ) at a V
SAT
of 1V, where I
SET
is the current
through R
SET
connected to pin CTRL.
The AS1102, AS1103, and AS1104 LED currents are
230 x I
SET
(per LED, typ) at a V
SAT
of 150mV and 325 x
I
SET
(typ) at a V
SAT
of 1V.
The AS1101, AS1102, and AS1104 incorporate a chip-
enable feature via pin ON. When the devices are dis-
abled, the supply current drops to less than 1μA.
The AS1101, AS1102, and AS1103 are available in a
6-pin SC70 package; the AS1104 is available in a 8-pin
MSOP package.
