Note

1. This parameter is derived from characterization.

2. This parameter is derived from the change in current limit measured at 1x and 4x of the di/dt shown in the

ILIMIT specification.

3. Auto-restart on time has the same temperature characteristics as the oscillator (inversely proportional to

frequency).
