2 / 14 page  AS1101, AS1102, AS1103, AS1104 Low-Dropout LED Drivers Dat a Sh eet www.austriamicrosystems.com Revision 1.5 1 - 13 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 (RSET). The AS1101 LED currents are 460 x ISET (per LED, typ) at an LED cathode voltage (VSAT) of 150mV and 650 x ISET (typ) at a VSAT of 1V, where ISET is the current through RSET connected to pin CTRL. The AS1102, AS1103, and AS1104 LED currents are 230 x ISET (per LED, typ) at a VSAT of 150mV and 325 x ISET (typ) at a VSAT 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. Figure 1. Typical Application Diagrams 2 Key Features !
