12.3 DrMOS compatibility
The PIP213-12M can be configured to be compatible with the Intel DrMOS specification.
Conformance to the Intel DrMOS specification requires that an external power supply to
the V_DDG pin is used and hence the internal V_DDG regulator must be disabled by
connecting the VDDG_EN pin to V_SSC.
