Atmel LED Driver-MSL2100
8-string, High-power, White or RGB LED Drivers for TVs,
Monitors, or Intelligent Solid-state Lighting
The MSL2100 features a 1MHz I 2 C serial interface. The interface supports
video frame-by-frame LED string intensity control for up to 16 interconnected
General Description
The Atmel ? LED Driver
MSL2100 compact, high-
power LED string driver uses
external MOSFETs to provide
up 1A per string, with current
accuracy and matching better
than ±1%. The MSL2100
drives eight parallel strings
of LEDs, and offers fault
detection and management of
open and short circuit LEDs.
devices, allowing active area dimming when used for video displays. The
advanced PWM engine synchronizes with the video signal, and offers phase
shifted string drive, virtually eliminating waterfall noise and motion blur.
The MSL2100 adaptively controls up to three DC-DC converters,
which power the LED strings, using patented Atmel's Driver Adaptive
SourcePower? technology. These Efficiency Optimizers minimize power use
while maintaining LED current accuracy, and allow up to 16 interconnected
devices to automatically negotiate the optimum power supply voltages.
A unique combination of peak current control and pulse width dimming
management offers simple full-screen brightness control, versatile area
dimming, and a consistent white point. LED string current is set for each
string using a current sense (FET source) resistor. LED current is also digitally
controlled for all eight LED strings. Global string drive pulse width is adjusted
with a 6-bit global intensity register, and individual string pulse width is
modulated with 8-bit control. Additionally, the MSL2100 optionally throttles
back the PWM on time of all strings when the temperature of the LEDs
exceeds a programmable threshold.
The MSL2100 monitors for string open circuit, LED short circuit, loss-of-sync
and over temperature faults, and provides a hardware fault output to notify the
MCU. Detailed fault status and control are available through the serial interface.
Additionally, the MSL2100 includes an on-chip EEPROM that allows the
power-up default register settings to be customized via the serial interface.
The MSL2100 is offered in a 6 x 6 x 0.85mm, 48-pin QFN package, and
operates over a -40°C to +85°C temperature range.
