8.4.2 TPS389006 Power ON

When the TPS389006 is powered ON, BIST is optionally executed (depending on TEST_CFG.AT_POR register bit); I2C and fault reporting (through NIRQ) become active as soon as BIST is completed and configuration is loaded from OTP (assisted by ECC, supporting SEC-DED).

The details of the configuration load ECC and BIST results are reported in TEST_INFO register.

Upon detection of the ACT rising edge, the TPS389006 starts the sequence timeout timer and the monitoring of the power ON sequence. SLEEP is ignored until ACT is High and the sequence timeout has expired. The TPS389006 will then act on SLEEP transitions to monitor/record Sleep Entry/Exit sequences.

BIST completion can be detected through interrupt or register polling:

  • Interrupt: INT_TEST.I_BIST_C flag is set and NIRQ is asserted if IEN_TEST.BIST_C=1
  • Polling: VMON_STAT register can be polled to read the ST_BIST_C bit
