3-CHANNEL CONSTANT CURRENT LED DRIVERS
WITH LED OPEN DETECTION
General Description
DM412 is a PWM enabled LED driver specifically designed for LED video display or lighting
applications. Each channel has linear adjustable 16-bits (65536 steps) grayscale PWM control
current outputs. It incorporates shift registers, data latches, 3-channel constant current circuitry with
current value set by 3 external resistors, and built-in oscillator for PWM functioning. Data, clock,
and latch buffer outputs are designed for cascading another chip. Its built-in open detection function
help users locate LED failures without additional circuits. The output polarity reverse function is
designed for more high power LED applications.

Constant-Current Output
Constant-current value of each output channel is set by an external resistor connected between
the R(G、B)REXT pin and GND individually. The current scale ranging can be adjusted from 5mA
to 200mA by varying the resistor value. The output current value is calculated by the following
equation:

Input Data Format
LED Open Detection
DM412 provides a real time monitor of LED open detection function without extra components
or circuit design. It will be identified as a LED open failure when the output is turned on but the
output voltage is below 0.3V. The test result of each channel will write to its correspondent shift
register which is in LSB position (R[0], G[0], B[0]) while strobe signal is active. User can refer to
timing diagram on page12. Detecting report could be retrieved from serial-out (DAO) data. If the
system reads ‘1’ back, that indicates LED is in normal status. But if ‘0’ was retrieved then LED
open failure has occurred. In order to make sure LED open detection function is in well operating
condition, it is recommended that all the luminance data are wrote to ‘1’ then almost turning on the
outputs during detection process.

Output Modulation Technique
In order to minimize the harmonic noise and increasing current accuracy, DM412 provides a
new LED drive technique of output modulation. It mixes traditional Pulse Width Modulation (PWM)
represented by MSB 8 bit (Bit[15:8]) with Bit Angle Modulation (BAM) represented by LSB 8 bit
(Bit[7:0]). The main benefit of BAM is to drive LED with an equivalent multiple frequencies in the
lower intensity of LED light output. Each bit of BAM binary code is effectively allocated a fixed
width of phase angles within a modulation cycle. The reference table shows the ratio defined by the
binary significance of each bit:

Power Dissipation
The power dissipation of a semiconductor chip is limited to its package and ambient
temperature, in which the device requires the maximum output current calculated for given
operating conditions. The maximum allowable power consumption can be calculated by the
following equation:
Pd(max)(Watt) =
Tj(junction temperature)(max)(°C)– Ta(ambient temperature)(°C)
Rth(junction-to-air thermal resistance)(°C/Watt)
The relationship between power dissipation and operating temperature can be refer to the figure
below:
Power Dissipation Pd(W)
3.0
Tj(max)=140 °C
2.5
Rth(TSSOP16)=55 °C/Watt
TSSOP16
Rth(SOP16)=81.2 °C/Watt

Ambient Temperature Ta(°C)
Based on the Pd(max), the maximum allowable voltage of output terminal can be determined by the
following equation:
VoutR × IoutR × DutyR + VoutG × IoutG × DutyG + VoutB × IoutB × DutyB < Pd(max)(W)– VCC(V) × IDD(A)
