5.1 Supply Circuit
The Supply pin V
S
is protected against ESD pulses as shown in Figure 5. Due to an internal voltage regulator the
device can be supplied from battery line.

5.1.1 Under Voltage Lock Out / Power On Reset
In order to ensure a stable device behavior under all allowed conditions the Supply voltage V
