16-bit Constant Current LED Driver
with Error Detection
General Description
DM13C is a constant-current sink driver specifically designed for LED display applications.
The device incorporates shift registers, data latches, and constant current circuitry on the silicon
CMOS chip. The maximum output current value of all 16 channels is adjustable by a single external
resistor. Its built-in open/short detection circuits help users detect LED failures. System retrieve the
error messages to indicate which channel has failure by serial output data. The thermal shutdown
function provides the over temperature protection.

Constant-Current Output
Constant-current value of each output channel is set by an external resistor connected between
the REXT pin and GND. Varying the resistor value can adjust the current scale ranging from 5mA to
90mA. The reference voltage of REXT terminal (Vrext) is approximately 1.2V. The output current
value is calculated roughly by the following equation:

Serial Data Interface
The serial-in data (DAI) will be clocked into 16 bit shift register synchronized on the rising
edge of the clock (DCK). The data ‘1’ represents the corresponding current output ‘ON’, while the
data ‘0’ stands for ‘OFF’. The data will be transferred into the 16 bit latch synchronized on the
rising edge (edge trigger) of the strobe signal (LAT); otherwise, the data will be held. The latch
pulse should be sent after the falling edge of the last clock within a frame data. The trigger timing of
the serial-out data (DAO) will be shifted out on synchronization to the rising edge of the clock. All
outputs are turned off while enable terminal (EN) is kept at high level. And they are active when EN
shifts to low.

Thermal Shutdown
During operation, when the junction temperature of the IC will reach approximately above
180℃, it will cause the driver to shutdown all the outputs. Basically, the IC will cool down and
return to the safe operating temperature which is approximately below 110℃. DM13C will restart
all the outputs at the same time. Operation in the thermal situation for a long time may cause chip
damage permanently.

LED Open/Short Detection
The result of open/short detection of DM13C could be retrieved from serial-out (DAO) data. It
will be identified as a LED open failure when the output is turned on but the output voltage is below
0.3V. And then it will be identified as a LED short failure when the output is turned on but the
output voltage is above 1/2 VCC.
To set up with the following conditions: (1) the image data written in shift register
corresponding to particular output channel is ‘1’; (2) the output enable terminal is activated
(EN=‘L’); (3) the rising edge of the latch signal (LAT), DM13C will execute LED open/short
detection then renews the results within the corresponding shift register.
By using the error message retrieved from serial-out data, system can recognize the status of
every LED driven by each channel. For either LED open or short detection, the original image data
is written to ‘1’ but ‘0’ is retrieved then a LED failure has occurred. If the image data is written to
‘0’ or the output enable terminal is inactive (EN=‘H’), it will not execute any detection process for
the corresponding channel. Therefore, system still retrieves the original image data.

DM13C
Real-time monitor
With the above operating principle, system could continuously retrieve LED status from
serial-out then compare with the last frame data one by one. Once there is any discrepancy
(‘1’‘0’), we can locate which channel is abnormal precisely. Since the process is ongoing and
without shifting between image mode and detection mode, it does not interrupt the image data flow
and the output display. The ‘real-time monitor’ method is suitable for LED Variable Message Signs
(VMS) system.
Clocks calculation
For large LED display applications, ‘real-time monitor’ could be a heavy loading for system
because it needs to compare the retrieved information with a lot of frame data. Therefore, to write
the image data of all channels to ‘1’, all failure status will be identified when there will be any ‘0’
retrieved. By calculating the numbers of clock pulses, the locations of abnormal channel could be
pointed out easily. The “clocks calculation” method helps to minimize the loading and memory
resources of system.
Selection of Open/Short Detection
The default detection type provided by DM13C is LED open detection after power-on. Users
could switch LED open to short detection (or short to open detection) by following timing sequence.
There are two alternative options could be selected. The option 1 shows triggering latch pulse when
the last clock of the frame data kept at high level. The option 2 shows sending one useless clock
pulse which will not shift-in data while the latch signal is kept at high level.

Threshold of Short Detection
The default threshold voltage for LED short detection of DM13C is 1/2 VCC. One could
change the default voltage by switching or setting a new voltage of VLED during short detection is
going on. Please see the example below for reference:

Example for shifting the threshold of LED short detection
Note that the VSHORT should be satisfied with the following inequality:
1 VCC < VSHORT < 1 VCC + VF(LED forward voltage) × N(Numbers of LED in a string)

The new threshold voltage of short detection will be equivalent to:
1 VCC + ( VLED–VSHORT )

Outputs Delay
Large in-rush currents will occur when the system activates all the outputs at once. To reduce
this effect, DM13C is designed to have a constant unit of delay (around 1.5ns) between outputs. The
delay for every output goes like this: there is no delay for OUT15 and OUT7, 1 unit of delay for
OUT14 and OUT6, 2 units of delay for OUT13 and OUT5 and so on.
Global Brightness Control
DM13C has no built-in global brightness control feature. In order to obtain a lower resolution
of global brightness control effect, two methods could be utilized. One is providing PWM signal
synchronized on latch pulse to modulate the output enable terminal (EN pin). The other is to adjust
the Rrext value or voltage drop across the external resistor. Please see the reference circuit below:

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:

Tj(max)=150C

The power consumption of IC can be determined by the following equation and should be less than
the maximum allowable power dissipation:
Pd(W) = VCC(V) × IDD(A) + Vout0 × Iout0 × Duty0 + …… + Vout15 × Iout15 × Duty15 < Pd(max)(W)
