ALED1262ZT Monolithic 12 Output LED Driver STMicroelectronics ALED1262ZT Monolithic 12 Output LED Driver is designed for automotive exterior and interior lighting applications. The STMicroelectronics ALED1262ZT has a 19V output driving capability connecting several series LEDs. In the output stage, twelve regulated current sources provide a constant current from 6mA to 60mA to drive LEDs. A single external resistor programs the current. In the ALED1262ZT, LED open error detection is available.
