This parameter is a design characteristic, not production tested. 20. The hold off circuit is designed to operate over the full operating range of VBAT. The specification indicates the conditions used in production test. 21. Desaturation is measured as the voltage drop below VBAT, thus the threshold is compared to the drain-source voltage of the external high-side FET. See Figure 5. 22. As long as one input is within VCM the output is guaranteed to have the correct phase. Exceeding the common mode rails will not cause a phase inversion on the output. 23. Input resistance is impedance from high-side source and is referenced to ground. Approximate tolerance is ±20%. Table 3. Static Electrical Characteristics (continued) Characteristics noted under conditions 8.0V ≤ V PWR =VBAT ≤ 40V, -40°C ≤ T A ≤ 125°C, unless otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted. Characteristic Symbol Min Typ Max Unit |
