    Thread Summary
    
                The user inquired about the MAX20058 IC's response if pin 6 (RT/SYNC) is left open, shorted to VCC, or shorted to SGND. The final answer indicates: open pin results in slow clock frequency and no regulation; shorted to VCC results in no clock frequency and no regulation; shorted to SGND results in high clock frequency and no regulation. The absolute maximum ratings for RT/SYNC are -0.3V to VCC + 0.3V, but the device's behavior under these conditions is not guaranteed.

    What would be the response of the MAX20058 IC if pin 6 (RT/SYNC) is left open, shorted to VCC (pin 3), or shorted to SGND (pin 11)?
    

    This information is needed for evaluating the FMEDA (failure modes and failure rates) for our device that uses the MAX20058.
