TLC59208F: Recommended operating conditions

Isee

Part Number: TLC59208F

Hi Team,

Can you please help me understand if a 3V supply with +/- 5% tolerance over temperature range (hence min. 2.85V) is acceptable or if it has to be at least 3Vmin? Thank you!

Regards

Andreas

In addition to the supply voltage: do you recommend ESD measures when using the driver? The distance between PWM drivers and LEDs is relatively short (2 inches). I assume that the FETs switch slow enough, there is nothing to find about it in the datasheet.

Hi Sir,

I have assigned this question to the proper person, since we are on holiday, reply maybe delay, please be patient. Thanks.

Hi Andreas,

The supply voltage should at least be 3V as mentioned in the datasheet.

How about the other question: do you recommend ESD measures when using the driver? The distance between PWM drivers and LEDs is relatively short (2 inches). I assume that the FETs switch slow enough, there is nothing to find about it in the datasheet.

I am sorry - I did not mean ESD, I meant to say radiated emissions: the distance between the driver and LEDs is 5cm. Should they be concerned about EMI? Should they implement measures? How fast are the FETs switching? Regards, Andreas

Hi Andreas,

Sorry, we couldn't provide the accurate data relating to the speed of FETs since it is related to many facts(vary between different application board). I suggest that you can measure it in practice in your actual system.
