Description
The LED6001 device is a LED driver that
combines a boost controller and a 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. The
brightness of the LEDs can be controlled through
PWM dimming and analog dimming (10:1 ratio)
by means of two independent pins. Enhanced
PWM dimming can be obtained thanks to
a MOSFET in series with the LED string and
directly driven by a dedicated pin.
The high-side current sensing, in combination
with a P-channel MOSFET, provides an effective
protection in case the positive terminal of the LED
string is shorted to ground. The high precision
current sensing circuitry allows a LED current
regulation reference within ï±ï 4% accuracy over
the whole temperature range and production
spread.
A fault output (open-drain) informs the host
system about faulty conditions: device
overtemperature, output overvoltage
(disconnected LED string) and LED overcurrent.
