The AS110x family are LED drivers providing matched current source bias for any color LED, including white and blue. LED current is programmable using an external resistor.

The AS1101 LED currents are typical 460 x ISET (per LED) at an LED cathode voltage of 150mV and typical 600 x ISET at an LED cathode voltage of 1V. The AS1102, AS1103, and AS1104 LED currents are typical 230 x ISET (per LED) at an LED cathode voltage of 150mV and typical 300 x ISET at an LED cathode voltage of 1V where ISET is the current through the external resistor connected to the CTRL pin.

The AS110x family can drive up to 4 high-current LEDs. The AS1101, AS1102, and AS1104 incorporate a chipenable feature via pin ON. When the devices are disabled, the supply current drops to less than 1µA. The devices are pin-to-pin compatible to the FAN5611, FAN5612 and FAN5614.

The AS1101, AS1102, and AS1103 are available in a 6-pin SC70 package; the AS1104 is available in a 8-pin MSOP package.
