Note 5: Minimum and maximum limits are guaranteed but may not be 100% tested.
Note 6: These voltage values are calculated and not 100% tested. The voltages are based on 100% tested
sense currents, an external “shift” resistor of 3.83MΩ from VLOW to VNN and another 3.83MΩ
resistor from VHIGH to VPP, and the on board sense resistor values of 1.27MΩ for VNN, and 1.4MΩ
for VPP. In addition, worse case resistor tolerances (+/-1%) were used to calculate the minimum and
maximum values. Please refer to the Overvoltage and Undervoltage section of the Applications
Information for a more detailed explanation.
