1)
The Detection Threshold V
DET
is far below the specified supply voltage range of analog and digital parts of the
T-SMINT
. Therefore, the board designer must take into account that a range of voltages is existing, where
neither performance and functionality of the T-SMINT
are guaranteed, nor a reset is generated.
2)
If the integrated Power-On Reset of the T-SMINTO is selected (VDDDET =
0
) and the supply voltage V
DD
is
ramped up from 0V to 3.3V +/- 5%, then the T-SMINTO is kept in reset during V

V
DD
must be ramped up so slowly that the T-SMINTO leaves the reset state after the oscillator circuit has
already finished start-up. The start-up time of the oscillator circuit is typically in the range between 3ms and
12ms.
