  • The ALED8102S is a monolithic, low voltage, 8 low-side channels. The ALED8102S guarantees up to 20 V output driving capability allowing users to connect several LEDs in series. In the output stage, 8 regulated current sources provide from 5 mA to 100 mA constant current to drive the LEDs. Current is programmed though a single external resistor.The ALED8102S is equipped with a thermal management that protects the device forcing it in shutdown (typically: power-off at 170 °C with 15 °C hysteresis to restart). The thermal protection switches OFF the output channels only. The operative supply voltage range is between 3 V and 5.5 V. The output control is provided by four switch inputs, proving an on/off toggle action suitable also for local dimming. Moreover, on all active output LEDs brightness can be adjusted with a global PWM signal applied to the output enable pin (OE). Outputs can be connected in parallel, or left unconnected if not used, as required by the application.
