DLPS223A December 2021 – February 2023 DLPC4430
PRODUCTION DATA
In order to set up the power monitor to trip within the DLPC4430 controller minimum supply voltage specifications, it is recommended that the external power monitor generating POSENSE targets its threshold to 90% of the minimum supply voltage specifications and ensures that POSENSE remains low a sufficient amount of time for all supply voltages to reach minimum device requirements and stabilize. Note that the trip voltage for detecting the loss of power, as well as the reaction time to respond to a low voltage condition is not critical for POSENSE as PWRGOOD is used for this purpose. As such, PWRGOOD has critical requirements in these areas.
