PRODUCTION DATA
The start-up and shutdown of the device is controlled by several PMBus programmable values including:
With the default (02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG(02h) ON_OFF_CONFIG settings, the timing is as shown in Figure 6-6. See the Supported PMBus CommandsSupported PMBus Commands for full details on the implementation.
The TPSM8S6B24S requires time between the AVIN and VDD5 reaching the UVLO levels for pin-detection and PMBus communication and valid sensing of EN/UVLO and PVIN_OK. After AVIN and VDD5 exceed the lower UVLO thresholds (2.9V typical), the TPSM8S6B24S starts the power-on-reset, self-calibration, and pin-detection. This time delay, tdelay(uvlo_PMBus) (6ms typical) must be complete before PVIN_OK or EN/UVLO sensing is enabled.
If VDD5PS_ON, PVIN_OK, and EN/UVLO are above the thresholds before the end of tdelay(uvlo_PMBus), (60h) TON_DELAY(60h) TON_DELAY starts after tdelay(uvlo_PMBus) completes.
If VDD5PS_ON, PVIN_OK, or EN/UVLO are below the thresholds when tdelay(uvlo_PMBus) completes, (60h) TON_DELAY(60h) TON_DELAY starts when VDD5_OK, PVIN_OK, and EN/UVLO are all above the thresholds.
