STMicroelectronics ALED8102S
The ALED8102S is a monolithic, low voltage, 8 low-side channels LED driver. The ALED8102S guarantees up to 19 V output driving capability allowing users to connect several LEDs in series. 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).| Part No. | ALED8102S |

In the output stage, 8 regulated current sources provide from 5 mA to 100 mA constant current to drive the LEDs. Current is programmed through a single external resistor. 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, providing an on/off toggle action suitable also for local dimming.
