Power supply
The power supply has been designed to address a wide range of DC bus voltages from 5 to
48 V. Three power supply configurations have been implemented.

To supply the 5 volts to the micro, you can use either the Vref signal of the L4976D regulator
if it is used (high voltage setting in
configured by putting J8 between pins 2-3 and the second configuration by putting J8
between pins 1-2.
With the L4976D’s Vref signal, it is possible to provide the microcontroller with up to 20 mA.
With the LK112SM50TR it is possible to provide up to 200 mA.
Power stage
The power stage is based on six power MOSFETs in full 3-phase bridge configuration. The
board has three STS8DNH3LLs in SO-8 package, each containing two devices. The
maximum driving current is 8 A and the suggested maximum driving voltage is 24 V.
Different power MOSFET devices can be used, replacing U15, U17 and U18 with other
devices. Compatible devices are power MOSFETs in SO-8 package containing single or
Medium voltage
Low voltage: 5–6.5 volts based on the L5970 boost converter.
Medium voltage: a 6.5–9-volt direct connection to the bus.
High voltage: 9–48 volts based on an L4976 buck converter (for V
MOSFET must be replaced with the STD20NF06LT4 or STS7NF60L).
