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 high-brightness LEDs. The device is compatible with multiple topologies such as boost, SEPIC and floating load buck-boost. PWM dimming of the LED brightness is achieved by means of an external MOSFET in series with the LED string and directly driven by a dedicated pin. 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. The high-side current sensing, in combination with a P-channel MOSFET, provides effective protection in case the positive terminal of the LED string is shorted to ground. The high precision current sensing circuitry allows an LED current regulation reference within ± 4% accuracy over the entire temperature range and production spread. A fault output (open-drain) informs the host system of faulty conditions: device overtemperature, output overvoltage (disconnected LED string) and LED overcurrent.
