ZHCSNL3A December 2021 – November 2023 TPSM8D6C24
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 section for full details on the implementation.
The TPSM8D6C24 requires time between the AVIN and VDD5 reaching their UVLO levels for pin-detection and PMBus communication and valid sensing of EN/UVLO and PVIN_OK. Once AVIN and VDD5 exceed their lower UVLO thresholds (2.9-V typical), the TPSM8D6C24 starts its power-on-reset, self-calibration, and pin-detection. This time delay, tdelay(uvlo_PMBus) (6-ms typical), must be complete before PVIN_OK or EN/UVLO sensing is enabled.
If VDD5PS_ON, PVIN_OK, and EN/UVLO are above their thresholds before the end of tdelay(uvlo_PMBus), (60h) TON_DELAY starts after tdelay(uvlo_PMBus) completes.
If VDD5PS_ON, PVIN_OK, or EN/UVLO are below their thresholds when tdelay(uvlo_PMBus) completes, (60h) TON_DELAY starts when VDD5_OK, PVIN_OK, and EN/UVLO are all above their thresholds.
