TB62718AF
Controller and Driver for Full-color LED Modules and Panels
TB62718AF
The TB62718AF is an LED driver which is suitable for driving
full-color LED modules. This device has built-in 8 bit PWM
grayscale and an output current adjustment functions. It can
turn on to 16 LEDs. This device has a heat sink fitting side on the
surface of the package. Then, a heat sink will dissipate heat
generated in the device. In addition, this device incorporates
built-in TSD (thermal Shutdown) and output-open detection
functions to protect the device.
Weight: 0.26 g (typ.)
Features
• Output current capability and number of outputs: 90 mA × 16 outputs
• Constant current range: 5 mA~75 mA
• Application output voltage: 0.7 V (output current 5 mA~90 mA)
• Adjustment function
1. Standard current adjustment (8-bit serial data input)
This function supports standard current adjustment using an external resistance connected to the REXT pin.
2 high-order bits … Output current can be adjusted to any one of 4 levels in the range 25%~100%.
6 low-order bits … Output current can be adjusted to any one of 64 levels in the range 40%~100%.
2. Each dot adjustment (128-bit serial data input)
This function allows adjustment of the current value for each output (dot).
… Output current can be adjusted to any one of 64 levels in the range 20%~100%.
3. All dot adjustment 1 (8-bit parallel data input)
This function allows adjustment of brightness for each LED module.
5 low-order bits … Output current can be adjusted to any one of 32 levels in the range 50%~100%.
4. All dot adjustment 2 (8-bit parallel data input)
This function allows changes to the frequency of the PWM clock and allows major brightness adjustment for
the display.
3 high-order bits … PWM clock frequency can be adjusted to any one of 8 levels in the range 1/1~1/8.
5. 256-grayscale PWM function (8-bit parallel input)
This function controls the pulse width for each output, yielding 256 grayscales.
Maximum PWM clock frequency 10 MHz (for all temperature range), Minimum pulse width 2 ms
• Accuracy of bits in constant-current output levels prior to adjustment
±6.0% max (for output current of 40 mA~80 mA)
±7.0% max (for output current of 20 mA~40 mA)
±12.0% max (for output current of 5 mA~20 mA)
• Protection functions
1. Thermal shutdown function (TSD)
This function monitors the rise in junction temperature.
Connect a pull-up resistor to the ALARM1 pin in order to monitor the temperature.
2. Output Pin Open Detection function
This function detect when an output pin is open.
Connect a pull-up resistor to the ALARM2 pin in order to monitor this.
• For anode-common LEDs
• Input signal voltage level: CMOS level (Schmitt trigger input)
• Power supply voltage range VDD = 4.5 V~5.5 V
• Maximum output pin voltage: 26 V

Warnings
Short-circuiting an output pin to GND or to the power supply pin may destroy the device.
Take care when wiring the output pins, the power supply pin and the GND pins (VSS, VSS2).
Do not apply either positive or negative voltages to the heat sink on the surface of the IC.
In addition, do not solder anything to the heat sink.
