The Detection Threshold V
T-SMINT
neither performance and functionality of the T-SMINT ® are guaranteed, nor a reset is generated.
If the integrated Power-On Reset of the T-SMINTIX is selected (VDDDET = ’0’) and the supply voltage V
ramped up from 0V to 3.3V +/- 5%, then the T-SMINTIX is kept in reset during V

already finished start-up. The start-up time of the oscillator circuit is typically in the range between 3ms and
12ms.

must be ramped up so slowly that the T-SMINTIX leaves the reset state after the oscillator circuit has
