  • DRV595: Selected doesn't match with expected gain.

    Resolved
    Part Number: DRV595 Hello, i was alpha testing our new hardware and realized that the selected gain wasn't matching with our expected gain at all. However, the datasheet doesn't really tell how to calculate the output values in reference to the input…

  • DRV595: Some question about DRV595

    TI Thinks Resolved
    Part Number: DRV595 Other Parts Discussed in Thread: DRV8412 Dear Expert We need to output a voltage of more than 12V (may be 14-16V) and a current of more than 3.2A (may be 3.5-4A). What about DRV8412? It can out put 6A current continuously (but I am…

  • DRV595: some questions about DRV595 for TEC

    TI Thinks Resolved
    Part Number: DRV595 Other Parts Discussed in Thread: DRV593 , Hi team, My customer wants to use the DRV595 as the TEC driver. Do we have the DRV595EVM available? Whether we can use the DRV593 EVM to evaluate the DRV595? What's the formula of DRV595(OUTPUT…

  • DRV595: DRV595 higher power output

    Resolved
    Part Number: DRV595 Other Parts Discussed in Thread: CSD95373AQ5M , CSD I have been using the DRV595 to drive a TEC with success (4A, 12VDC) however I now need more current (up to 10A). Is there a higher current version of this IC or alternatively is there…

  • RE: DRV595: DRV595 in conjunction with a 2.7V DAC

    Resolved
    Hi Derek, I had three test boards made of my proposed circuit. It works as expected. I don't understand the phase delay you mention as the 1.45 V on IN- is constant and only the voltage to IN+ varies as the DRV595 requires. How is the DAC different…

  • RE: DRV595: DRV595 higher power version or alternate TI parts to drive a TEC?

    Hi Chris, Adding to Yanming's comment, the TPA3255 can drive this device but the input control is an analog signal rather than a PWM input like the DRV595. It also can only get up to 600kHz switching frequency on the output FETs. Best Regards, Robert…

  • DRV595: Is the diagnostic related to temperature?

    Part Number: DRV595 Other Parts Discussed in Thread: TEST Dear team, Here is a question about DRV595. Our customer use this chip in a TEC application. When they do the low temperature test, they found that if they put the chip(DRV595) and the TEC element…

  • DRV595: UNexpected Fault mode-

    TI Thinks Resolved
    Part Number: DRV595 HI Team, see attachment- we are also wondering the data sheet impiles that the input pins are biased at 3V ( says biased rathre then bias) and also DIFFERENTIAL OR SINGLE-ENDED INPUTS The differential input stage of the amplifier cancels…
