Notes:

1. LVD typical data are based on TA=25°C. They are given only as design guidelines and are not tested.

2. The minimum VDD rise time rate is needed to insure a correct device power-on and LVD reset. Not tested in production.

3. If the low LVD threshold is selected, when VDD falls below 3.2V, the device is guaranteed to be either functioning or

under reset.
