Atmel LED Drivers-MSL2160/MSL2161
16-string, White and RGB LED Drivers with Adaptive Configuration,
EEPROM, and SPI/I 2 C/SMBus Serial Interface
The MSL2160 features a 20MHz SPI bus, and the MSL2161 offers a 1MHz
I 2 C serial interface. Both interfaces support video frame-by-frame LED string
General Description
The Atmel ? LED Drivers-
MSL2160 and MSL2161
compact, high-power LED
string drivers use external
current control MOSFETs to
sink up to 350mA per string,
with current accuracy and
matching better than 1.5%.
The MSL2160/1 drive 16
parallel strings of LEDs, and
offer fault detection and
management of open and
intensity control for up to eight interconnected devices, allowing active area
dimming and phase shifted PWM dimming for improved performance. Both
devices include an advanced PWM engine that synchronizes PWM dimming
to the video signal for reduced motion blur and waterfall noise.
The MSL2160/1 adaptively controls the DC-DC converters that power the
LED strings using Atmel's Adaptive SourcePower? technology. This scheme
optimizes power consumption without sacrificing LED current accuracy.
Peak LED string currents are set using current sense resistors, and global
string current is adjustable with 8-bit control. Global string drive pulse width
is adjusted with an 8-bit global intensity register, and individual string pulse
width is modulated with 12-bit control.
The MSL2160/1 monitors the LED strings for open circuit, short circuit, loss-
of-sync, and over-temperature faults, and provide a hardware fault output
to notify the MCU. Detailed fault status and control are available through the
serial interface. Additionally, the MSL2160/1 includes an on-chip EEPROM
that allows the power-up defaults to be customized via the serial interface.
The MSL2160/1 are offered in 9 x 9 x 0.85mm, 64-pin TQFN packages and
operate over a -40°C to +105°C temperature range.
