For 3.5V<= V
LINSUP
<5V, the LIN/HV PHY is still working but with degraded parametrics.
2
For 5V<= V
LINSUP
<5.5V, characterization showed that all parameters generally stay within the indicated specification.

The V
LINSUP
voltage is provided by the VLINSUP supply. This supply mapping is described in device level
documentation.
