1.1
Power supply
The STEVAL-IME015V1 board is powered through connector CN10:
•
VDDP: 3.3V DC
•
VPP: positive high voltage, 0 to +200V DC
•
VNN: negative high voltage, 0 to -200V DC
•
RGND: bleeding resistor ground
•
GND: common ground

Connector
Description
CN12
RGND bleeding resistor ground is available on CN10 connector.
Default Setting.
RGND bleeding resistor ground is shorted at common ground at board level.
Do not connect any voltage on RGND CN10 connector.
1.2
STHV64SW switch block
The STHV64SW switch block is implemented with two power transistors and a bleeding resistor connected
between output OUT and RGND (a dedicated ground for resistors). All power supply nets are in common for each
switch.
