8.1.1.1 Successful Self-Test

Figure 11 shows a successful manual self-test timing with the PTT pin.

AFE3010 AFE3010_ptt_success.gifFigure 11. Successful Manual Self-Test Using PTT Pin
  1. The test sequence starts when PTT transitions from high to low.
  2. After a debounce time to ensure there is no false transition, the device starts the self-test.
  3. If the self-test passes, the SCR fires.
  4. The internal fault counter resets.
  5. The ALARM signal remains low to indicate the self-test passed.
  6. The PTT signal transitions low to high to complete the self-test event.
