Forum Post: TSC2046: AUX pin
Part Number: TSC2046 Hi, Should the AUX pin be tied with GND through the capacitor if the AUX pin is not used? If it is, how much capacitance is recommended? Best Regards, Kuramochi

Hi Sasa, It looks like you have your waveform sequences set up correctly: 0x04 = 0x01; 0x05-0x07 = 0xA0; 0x08 = 0x01. You are using the external TRIG edge mode, so to start the waveform, are you...

Hi Kelly, I'm using internal trigger via I2C by sending 0x01 to 0x0C register. I have tried playing only one effect, or only "pause" effect. It seems as every effect or pause are appended with short...

Hi Sasa, I see, this make me think that it has to do with the braking that is applied at the end of the waveforms in the library. Can you try running the effects in closed loop and see what the result is?

Hi Kuramochi-san, If the analog input (Aux pin) is not used, It must be tied to GND, but it isn't necessary to use a capacitor. Best Regards José Luis Figueroa Application Engineer

Hello Matthieu, I have asked my product engineer to find the ESD data for this device so we can compare it to your stated conditions. I will update you when I have the data.

Hello Matthieu, It is difficult to apply ESD test results to other overstress scenarios. It really depends upon the duration fo the pulse. An ESD pulse is only nanoseconds.

Hi Arthur That's odd, no customer had reported that this file doesn't work on Windows 7. Unfortunately, we don't have the source code of the driver for Windows 7, but you could use the source code of...

At the present time there is no difference. However, it appears that in the past, there needed to be two different part numbers because the CCMT was converted to RoHS compliance in 2006, but the BCMT...

Hello Hyungsung, TI does not guarantee the device to be operational if the absolute maximum ratings are exceeded. If the LM98725 experiences temperatures higher than 235 C, it is possible that it is...

Hi Mintack, The limitation of the pattern length to 64 pulses is coming from the device LM96570 .

Hi Kirby, I agree that it's difficult to use ESD test results for other tests but I would like to have an opinion. Could you explain me what could be the problem, is a thermal issue on the ESD diode...

Hi Yi-Bin, We do not currently have a driver to support this high frequency operation. What is the piezo capacitance that you want to drive at this high frequency?

Hi Kelly, The piezo capacitance is approximately 1.2 nF. Thanks for your support!

I would expect your conditions to damage the part. It is a thermal condition due to the long pulse time.
