STMicroelectronics ALED1262ZT 12-channel automotive LED driver

Click2Contact

The STMicroelectronics ALED1262ZT 12-channel LED driver targets advanced automotive rear combination lamps and interior lighting, bringing features to support complex and innovative visual effects.

Independent 7-bit PWM dimming on all channels allows flexible control of tail, stop and indicator lights, with dynamic effects. Each channel delivers constant output current at 19 V for controlling multi-LED series strings.

Adjustment from 6 to 60 mA ensures a wide dimming range with high maximum brightness. The LED lighting driver responds to I²C commands from a host microcontroller and provides two pre-programmed configurations that allow standalone operation for extra flexibility.

With diagnostic features including open-LED detection and overtemperature warning with thermal shutdown, the product offers long-lasting robustness and stability. The input-voltage range from 5.5 to 38 V allows use in direct battery-connected systems. In addition, the device is designed for low-noise operation, with slow turn-on/off time per channel and spread-spectrum clock operation to simplify integration with other in-vehicle electronics.
