FUNCTIONAL DESCRIPTION
Power Supply (VCC, +5V, VCCA, VCCB)
NCD57253 is designed to support unipolar power supply
on both individual channels.
The evaluation driver board supports two types of output
side power supply:
•
On board dc
−
dc converter.
♦
Powered by a common source as the input side of
NCD57253.
♦
Powered from external power pin VCC.
•
External power supply.
The evaluation driver board is designed to support bipolar
power supply, this is achieved by creating a virtual ground
connected to the MOSFET source. If bipolar power supply
is not required, VEEA / VEEB pin should be connected to
the GNDA / GNDB.
For more detailed settings see the Table 2.
