Description
The L6360 is a monolithic IO-Link master port compliant with PHY2 (3-wire) supporting COM1 (4.8 kbaud), COM2 (38.4 kbaud) and COM3 (230.4 kbaud) modes. The C/QO output stage is programmable: high-side, low-side or push-pull; also cut-off current, cut-off current delay time, and restart delay are programmable. Cut-off current and cut-off current delay time, combined with thermal shutdown and automatic restart, protect the device against overload and short-circuit. C/QO 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/QO pin), data received from a host microcontroller through the USART (IN C/QO pin), or to the USART (OUT C/QI pin) data received from PHY2 (C/QI 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.
