The Data sheet specifies the operation between either 1.71 V to 1.89 V or 2.25 V to 5.5 V. Is gap from 1.90 V to 2.24 V just because there is no electrical characterization data or because the device will not function in that range? Section 7.17 has parameter tPU indicates there is an UVLO. Is the UVLO always below 1.70V?
Thank you,
