TOSHIBA CMOS Integrated Circuit Silicon Monolithic

TCA62746AFG,TCA62746AFNG

16-Output Constant Current LED Driver with Output Open/Short Detection

The TCA62746 series are LED drivers with sink type constant

TCA62746AFG

circuit output, making them ideal for controlling LED modules

and displays.

The current value of the 16-output is configurable using one

external resistor.

In addition, these drivers are equipped with a function for

detecting the output voltage when the output load LEDs open or

short, and which then outputs the result as serial data.

These drivers consist of a 16-constant current output block, a

16-bit shift register, a 16-bit latch and a 16-bit AND-gate.

The suffix (G) appended to the part number represents a Lead

(Pb)-Free product.

Note 1:

Note 2:

The latch circuit is a leveled-latch circuit. Please exercise precaution as it is not triggered-latch circuit.

Keep the SLAT pin is set to “L” to enable the latch circuit to hold data. In addition, when the SLAT pin is set

to “H” the latch circuit does not hold data. The data will instead pass onto output.

When the OE pin is set to “L” the OUT0 to OUT15 output pins will go ON and OFF in response to the

data. In addition, when the OE pin is set to “H” all the output pins will be forced OFF regardless of the data.

Output Delay Circuit

This is designed for high speed switching between outputs and 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

PWM grayscale control

This IC is possible to PWM grayscale control by the input of the PWM signal to the EN terminal.

When PWM grayscale control is done, we recommend the LED power-supply voltage to be set to become the

satiety region of the constant current characteristic. When using this IC outside the saturation area, PWM grayscale

control cannot be normally done.

Description

In the OOD and OSD modes, the state of OE must be switched from “H” to “L”. And, then, This IC would

execute Open-/Short-circuit Detection as well as enabling output ports to drive current.

At least three clock must be inputs at the “L” state of OE and the third clock should be at least 2 µs after

the falling edge of OE . the detected error status into the built-in shift register is done by rising edge of

this third clock.

When OE is “L", the serial data cannot be input from the terminal SIN.

When OE is changed from “L" to “H", the error state code is output from the terminal SOUT

synchronizing with the clock.

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.
