Description
The L6360 is a monolithic IO-Link master port
compliant with PHY2 (3 wires) supporting COM1
(4.8 kbaud), COM2 (38.4 kbaud) and COM3
(230.4 kbaud) modes.
The C/Q_O output stage is programmable: high-
side, low-side or push-pull; also cutoff current,

cutoff current delay time, and restart delay are
programmable.
Cutoff current and cutoff current delay time,
combined with thermal shutdown and automatic
restart protect the device against overload and
short-circuit.
C/Q_O and L+ output stages are able to drive
resistive, inductive and capacitive loads. Inductive
loads up to 10 mJ can be driven.
Supply voltage is monitored and low voltage
conditions are detected.
The L6360 transfers, through the PHY2(C/Q_O
pin), data received from a host microcontroller
through the USART (IN C/Q_O pin), or to the
USART (OUT C/Q_I pin) data received from PHY2
(C/Q_I pin).
To enable full IC control, configuration and
monitoring (i.e. fault conditions stored in the
status register), the communication between the
system microcontroller and the L6360 is based on
a Fast mode 2-wire I²C.
The L6360 has nine registers to manage the
programmable parameters and the status of the
IC.
Monitored fault conditions are: L+ line,
overtemperature, C/Q overload, linear regulator
undervoltage, and parity check.
Internal LED driver circuitries, in open drain
configuration, provide two programmable
sequences to drive two LEDs.
