ALED6001：Automotive grade PWM-dimmable single channel LED driver with integrated boost controller
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.
