Reset Switching Threshold
The internally set reset threshold is 4.65 V. When using the TLE 4470 G (P-DSO-20-6)
this threshold can be adjusted to 3.5 V <
V
RTH
< 4.6 V by connecting an external voltage
divider to pin RADJ. If this pin is not needed, it can be left open or even better connected
to GND.
