Notes:
1.Functional and tested operating conditions are given in Table 2. Absolute maximum ratings are stress
ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those listed
may affect device reliability or cause permanent damage to the device.
2.Caution: MVIN must not exceed GVDD by more than 0.3 V. This limit may be exceeded for a maximum of
20 ms during power-on reset and power-down sequences.
3.Caution: OVIN must not exceed OVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20
ms during power-on reset and power-down sequences.
4.Caution: LVIN must not exceed LVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20
ms during power-on reset and power-down sequences.
5.(M,L,O)VIN and MVREF may overshoot/undershoot to a voltage and for a maximum duration as shown in
Figure 2.
