STMicroelectronics ALED6001
The ALED6001 is an automotive-grade (AECQ100 compliant) LED driver that combines a boost controller and high-side current sensing circuitry optimized for driving one string of highbrightness LEDs. The device is compatible with multiple topologies such as boost, SEPIC and floating load buck-boost. The pin that manages the LED current setting, usually connected to an external resistor, can also be used as analog control if a microcontroller is located in the LED module.| Part No. | ALED6001 |
