Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
3. During OTP programming, the maximum VDDP value is 5.7 V. This allows VDDP to be tied to VDD_OTP.
4. HPM10 is functional in this range, but is not supposed to meet specification in terms of voltages, currents, thresholds and precision.
5. We ensure that all parts will go into Deep Sleep Mode with a duration of the DS_EN signal longer than 100 us. However, 20 ms is the typical
minimum duration value, which means a typical part will trigger with a 20 us duration of DS_EN.
