ISO5852S-Q1: the device is smoking not pin 5

Part Number: ISO5852S-Q1

I am using ISO5852SQDWRQ1, and  the device is smoking not pin 5

I did exactly the same as the datasheet recommended (Figure 49). The IC smokes on pin 5 and its burnt. I used another one and still the same

My current limit is 1 Amp

Please any help

  • Hi Haider,

    It would help us understand the situation if you can share the schematic of your circuits with us.

    I just did figure 49. I test it as open loop.
  • In reply to Haider Mhiesan:

    The configuration of Figure 49 worked for us. It is hard to help you debug your circuit without knowing exactly how your circuit is setup up. I would recommend you to double check the power supply connections to make sure there is no short circuit between VCC and GND. To simplify the problem, you can connect DESAT pin to VEE2, and remove the DESAT diode. Let me know how it works, and we can discuss more.

    With Regards,

    Thanks for an amazing advice. Now it works after I have done what you suggested.
