Atmel LED Drivers-MSL2041/MSL2042
Low-cost, Simple 4-string LED Drivers with External Current Sink
MOSFETs, 5000:1 Dimming Range and Per String PWM Input
The MSL2041/2 adaptively control up to two DC-DC converters that power
the LED strings, using Atmel's Adaptive SourcePower? technology. These
General Description
The Atmel ? LED Drivers-
MSL2041 and MSL2042
compact, high-power LED
string controllers use external
current control MOSFETs to
sink up to 1A per string, with
string current matching of
±0.5%. The MSL2041/2 drive
four parallel strings of LEDs
and offer fault detection and
management of open circuit
and short circuit LEDs. The
MSL2041 features four PWM
inputs that allow independent
frequency, dimming and
phasing of each string, while
the MSL2042 offers one
PWM input for frequency and
dimming control of all four
strings, and automatically
phase shifts the string drive
signals. Peak string currents
Efficiency Optimizers minimize power use while maintaining LED current
accuracy. Multiple MSL2041/2s cascade to automatically negotiate the
optimum power supply voltage when driving more than four strings from a
single power supply.
The MSL2041/2 features fault control for open-circuit strings, LED short-
circuits and device over-temperature conditions. When a string open-circuit or
LED short-circuit condition is detected, the MSL2041/2 turn off the faulty string
and pull the open-drain fault output low.
The MSL2041/2 feature stand-alone operation, and the basic circuit requires
just one to four external PWM dimming inputs. An I 2 C serial interface is
provided to allow optional control and monitoring of the various fault detection
and Adaptive SourcePower parameters, but is not required for operation.
The MSL2041/2 are offered in the 32-pin, 300mil SOP package, and operate
over the -40°C to +85°C temperature range.
