16-Output constant current LED driver with the output gain control function and the PWM grayscale function
1.Feature
The TC62D723FNG is LED drivers which have the sink-type
constant current output.
The output gain control function of 8-bit and the PWM grayscale
function of 16, 14, 12, and 10-bit are built into this IC.
Output current value of 16 channels is set by one external
resistance.
In addition, the thermal shutdown function, the output open
detection function, and the output short detection function are built
in.
This IC is most suitable for lighting the LED module and the display.

SOUT is operation at the time of S6 command N0=0 conditions.
The first SCK (signal X) after this command is used for transmission of the output open/short detection result
data. The input from SIN is not received. Note1
Note1: This operation is performed when the output open/short detection function is “Active” setting.
The output open/short detection functions are set by S6 command.
Default setting is “Not Active”.
8-5) S4 command (Reset of the internal PWM counter.)
Operation) In the number of SCK pulses at TRANS="H" is 11 or 12, the following operation is executed.
The internal PWM counter is reset.
When the internal PWM counter is reset, the output is turned off.
Note) It is necessary to input S1 command to turn on the output again.

13. Thermal shutdown circuit (TSD)
When the temperature of internal IC exceeds 150°C, all constant current outputs are turned off by this function.
The constant current is outputted again when the temperature decreases to the rating.
The thermal shutdown function of this IC aims at stopping the influence (emitting smoke, ignition) on the
circumference (LED and substrate) to the minimum, when it is used on the conditions beyond not a function but
the absolute maximum rating for preventing destruction of IC and IC results in destruction.
Calculation of heat
Take care not to let the temperature of the internal IC exceed 150℃ by referring to the formula below.
Consumption power (IC output) [W] = (LED supply voltage [V] - Minimum of Vf of LED [V] )
× Output current [A] × number of output × (ON Duty [%] / 100 )
Consumption power (IC supply) [W] = IC supply voltage [V] ×IC supply current [A]
Total of consumption power [W] = Consumption power (IC output) [W] + Consumption power (IC supply) [W]
Heat value of internal IC [°C] = Thermal Resistance [°C / W] × total of power consumption [W]
Temperature of internal IC [°C] = Heat value of internal IC [°C] + Ambient temperature [°C]
In case used LED supply voltage is high, and heat value of internal IC is large.
Heat value of internal IC can be reduced by decreasing the voltage with the external resistance shown below.

Voltage that should decrease by external resistance [V]

Resistance for heat protection [Ω] = Voltage that should decrease by external resistance [V] / Output current [A]
14. Output delay function
This function is intended to have the effect of reducing switching noise by reducing the di/dt when all outputs are
ON or OFF at the same time.There is a switching time lag between outputs.
A switching time lag between outputs is put in order of the following.
OUT0 → OUT15 → OUT7 → OUT8 → OUT1 → OUT14 → OUT6 → OUT9 → OUT2 → OUT13 → OUT5 →
OUT10 → OUT3 → OUT12 → OUT 4 → OUT11

15. Power on reset (POR)
It avoids the malfunction by resetting all internal data of IC and setting default in startup.
POR circuit operates only when VDD rises from 0 V. To restart POR, VDD should be 0.1 V or less.
As for the voltage of storing the internal data, it is guaranteed after VDD reaches 3.0 V or more once.

Notes on design of ICs
1. Regarding decoupling capacitor between power supply and GND
It is recommended that decoupling capacitor between power supply and GND should place as near IC as possible.
2. Regarding resistors for setting of output current
When resistors for setting of output current (REXT) are used commonly by many ICs, in designing for mass production, take enough care in
evaluating IC operation.
3. Regarding PCB layout
There is only one GND terminal on this device when the inductance in the GND line and the resistor are large, the device may malfunction due
to the GND noise when output switching by the circuit board pattern and wiring.
Therefore, take care when designing the circuit board pattern layout and the wiring from the controller.
4. Please check the latest technical material at the time of mass production.

IC Usage Considerations
Notes on handling of ICs
[1] The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a
moment. Do not exceed any of these ratings.
Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by
explosion or combustion.
[2] Use an appropriate power supply fuse to ensure that a large current does not continuously flow in case of over
current and/or IC failure. The IC will fully break down when used under conditions that exceed its absolute maximum
ratings, when the wiring is routed improperly or when an abnormal pulse noise occurs from the wiring or load,
causing a large current to continuously flow and the breakdown can lead smoke or ignition. To minimize the effects
of the flow of a large current in case of breakdown, appropriate settings, such as fuse capacity, fusing time and
insertion circuit location, are required.
[3] If your design includes an inductive load such as a motor coil, incorporate a protection circuit into the design to
prevent device malfunction or breakdown caused by the current resulting from the inrush current at power ON or the
negative current resulting from the back electromotive force at power OFF. IC breakdown may cause injury, smoke
or ignition.
Use a stable power supply with ICs with built-in protection functions. If the power supply is unstable, the protection
function may not operate, causing IC breakdown. IC breakdown may cause injury, smoke or ignition.
[4] Do not insert devices in the wrong orientation or incorrectly.
Make sure that the positive and negative terminals of power supplies are connected properly.
Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the
rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or
combustion.
In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly
even just one time.
[5] Carefully select external components (such as inputs and negative feedback capacitors) and load components
(such as speakers), for example, power amp and regulator.
If there is a large amount of leakage current such as input or negative feedback condenser, the IC output DC voltage
will increase. If this output voltage is connected to a speaker with low input withstand voltage, overcurrent or IC
failure can cause smoke or ignition. (The over current can cause smoke or ignition from the IC itself.) In particular,
please pay attention when using a Bridge Tied Load (BTL) connection type IC that inputs output DC voltage to a
speaker directly.
Points to remember on handling of ICs
(1) Heat Radiation Design
In using an IC with large current flow such as power amp, regulator or driver, please design the device so that heat
is appropriately radiated, not to exceed the specified junction temperature (TJ) at any time and condition. These ICs
generate heat even during normal use. An inadequate IC heat radiation design can lead to decrease in IC life,
deterioration of IC characteristics or IC breakdown. In addition, please design the device taking into considerate the
effect of IC heat radiation with peripheral components.
(2) Back-EMF
When a motor rotates in the reverse direction, stops or slows down abruptly, a current flow back to the motor’s
power supply due to the effect of back-EMF. If the current sink capability of the power supply is small, the device’s
motor power supply and output pins might be exposed to conditions beyond absolute maximum ratings. To avoid
this problem, take the effect of back-EMF into consideration in system design.
(3) Thermal Shutdown Circuit
Thermal shutdown circuits do not necessarily protect ICs under all circumstances. If the thermal shutdown circuits
operate against the over temperature, clear the heat generation status immediately.
Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings can cause
the thermal shutdown circuit to not operate properly or IC breakdown before operation.
