FUNCTIONAL OPERATING CONDITIONS (Cont’d)
Figure 60. High LVD Threshold Versus V
Figure 61. Medium LVD Threshold Versus V
Figure 62. Low LVD Threshold Versus V
Notes:
1. LVD typical data are based on T
2. The minimum V
3. If the low LVD threshold is selected, when V
anteed to continue functioning until it goes into reset state. The specified V
on phase, but during a power down phase or voltage drop the device will function below this min. level.
