Tool/software:

I just want to know response time of driver to turn ON the LED

#TLC6C5712-Q1

Also what is the use of PWM pin of driver and how it is co related with each output.

Hello,

All of the timing requirements can be found from section 6.7 in the data sheet. If you are enabling the output from the latch, it is a maximum delay of 3000 ns. The maximum delay time from the PWM input to the output is 0.2 us.

The PWM pin allows for an external PWM input to control any output on the device. Each output has a value found in addresses 40h to 45h in the register map that can be programmed to any PWM pin.

If you have any other questions, please let me know.

Kind Regards,

Nicholas Alexander

can with 3 PWM input to driver can control all 12 output

Hello,

You can control all 12 outputs with just 3 PWM inputs but you must program each PWM_MAP_CHX in the register map. There is no memory in this device so this value will need programmed each time the device is power cycled.

Best,

Ok Thanks

Also all output diagnostic able with the three PWM its self or ant other specific requirement is there for Short circuit and open circuit detection.

Hello Sunny,

The short circuit and open circuit detection will work with any PWM configuration so it will work with three PWM. The ERR pin will pull low when a fault is detected and the register map can be read to determine the exact fault.
