Using STEVAL-IFP016V2

The STEVAL-IFP016V2 board can be used in combination with the STEVAL-PCC009V2 or

STEVAL-PCC009V1 demonstration board.

IC inputs can be controlled by the STEVAL-PCC009V2/1 or set by the hardware using

jumpers on the board.

The CON1 connector is used to supply the board. Supply voltage should be connected to

The 3.3 V or 5 V voltage for logic inputs and for the reference voltage is obtained from the

CON2 is used to provide input/output voltages from/to external circuits. The C/Q channel is

used for communication (transceiver line), L+ is used to supply an IO-Link device, L- is

shorted to GND and the I/Q channel is used as an additional input (communication) line.

3.1

Connection to the STEVAL-PCC009V2 or STEVAL-PCC009V1

demonstration board

The complete evaluation kit, apart from STEVAL-IFP016V2 also in the communication

board, is used to program the IC and to control UART communication.

A GUI interface is used to configure the L6360 IC through the communication board.

Basic supply protection circuit

A cost-effective supply voltage protection has been implemented, while reverse-polarity

protection has not.

Supply overvoltage protection is provided by the TR1 diode. It works as a primary

overvoltage clamp to limit supply line distortions - like surge pulses or oscillations caused by

line parasitic parameters (inductance) during the plug-in phase, for example. The rating of

1500 W is recommended to provide reliable protection. A unidirectional Transil must be used

to avoid negative stress on the L6360.

An energy buffer filters the application supply to avoid high ripple during power driver

switching, etc. C3 is used as the filtering bulk capacitor.
