6.13 Power-Up Timing Requirements

TYP UNIT
ten_dly PROJ_ON to 1.1 V enable. This includes PROJ_ON tglitch time. Rising edge of PROJ_ON to rising edge of 1.1 V enable. 11 ms
tmon1(1)(2) Maximum time for 1.1 V rail to reach voltage threshold after enable has been asserted. This delay length will occur even if 1.1 V meets threshold earlier. Rising edge of ENB_1P1V to internal 1.1 V monitor test. 10 ms
tmon2(1)(2) Maximum time for 1.8 V rail to reach voltage threshold after enable has been asserted. This delay length will occur even if 1.8 V meets threshold earlier. Rising edge of ENB_1P8V to internal 1.8 V monitor test. 10 ms
tmon3(1)(2) Maximum time for 3.3 V rail to reach voltage threshold after enable has been asserted. This delay length will occur even if 3.3 V meets threshold earlier. Rising edge of ENB_3P3V to internal 3.3 V monitor test. 10 ms
tw1 RESETZ delay after voltage testing completion. Completion of 3.3 V monitor test to RESETZ rising edge. 10 ms
(1) V1P1V, V1P8V, and V3P3V rails can be enabled prior to the TPS99000-Q1 assertion of their respective enable signal if required for system power design. If necessary, ENB_1P1V may be connected to the 1.1 V, 1.8 V, and 3.3 V external supply enables.
(2) If any voltage threshold is not met within the specified time, the TPS99000-Q1 will not de-assert RESETZ. The power-up procedure must be fully restarted in this situation.
