L6258EA is a dual full bridge for motor control applications realized in BCD technology, with the capability of driving both windings of a bipolar stepper motor or bidirectionally control two DC motors. L6258EA and a few external components form a complete control and drive circuit. It has high efficiency phase shift chopping that allows a very low current ripple at the lowest current control levels, and makes this device ideal for steppers as well as for DC motors. The power stage is a dual DMOS full bridge capable of sustaining up to 40V, and includes the diodes for current recirculation.The output current capability is 1.5A per winding in continuous mode, with peak start-up current up to 2A. A thermal protection circuitry disables the outputs if the chip temperature exceeds the safe limits.

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/QOoutput 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/QOand 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/QOpin), data received from a host microcontroller through the USART (IN C/QOpin), or to the USART (OUT C/QIpin) data received from PHY2 (C/QIpin). 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.

The L6364 is a dual channel transceiver for industrial sensor applications. It has been designed to support even the IO-Link standard and acts as a bridge between a microcontroller with a sensor or actuator function and a 24 V supply and signaling cable. In normal operation the L6364 is configured at start up by the microcontroller via the SPI interface. Typically, the L6364 then operates as a Single Input Output device driving the output lines as configured by the microcontroller. If the device is connected to an IO-Link master, then the master can initiate communication and exchange data with the microcontroller while the L6364 acts as a physical layer for the communication.The L6364 integrates a surge pulse suppressor circuit featuring the protection of the process side pins (VPLUS, CQ, DIO, PGND) against up to ±1.5 kV/50 us withstand pulses applied with 500 Ω coupling. Also, the same pins are protected against reverse polarity (Surge pulse and reverse polarity protections). The two symmetrical input/output stages (CQ and DIO) can be used either for the communication through the 24 V data bus or to drive industrial loads. Each output stage can be configured (Hi-Z, High Side, Low Side, Push-Pull) and protected against overload by the ISET programmable threshold (110 mA to 250 mA). Also, the JOIN mode configuration allows to reduce power dissipation and to double overload threshold by shorting CQ and DIO on the application. The IC embeds two linear regulators (V3V3 and V5V) than can work either directly supplied by the external supply rail (VPLUS) or by the high efficiency and configurable (VSET, fSET) embedded DC-DC converter. The output voltage of the DC-DC can be used as additional supply rail for the application. The total current capability (IOUT) of the internal regulators and DC-DC is 50 mA. The logic core of the IC is internally supplied by the V3V3 rail and communicates with the external microcontroller by an SPI (slave) interface, an interrupt signal (INT) and direct driving of DIO line (CTLD). The VDIG pin defines the voltage rail of these digital signals: it enables the IC to work even with microcontroller supplied by different rails than V3V3. The internal logic embeds an IO-Link UART peripheral that can be configured by the microcontroller in one of the three possible options: Transparent, Single-octet or Multi-octet (IO-Link UART peripheral). In Transparent mode the IC works purely as a physical layer between the microcontroller and the 24 V data bus: the workload for the management of the input/output data is fully demanded to the firmware running on the microcontroller. In Single-octet and Multi-octet modes the IC itself does a set of IO-Link required checks on the input/output data with consequent drastic reduction of the workload for the microcontroller. The Multi-octet is usually preferred when the data transfer with the IO-Link master can be managed by the available 8-bits registers buffer: the IC generates an interrupt to microcontroller when all data in the buffer are ready. If IO-Link data transfer exceeds the IC buffer capability, then Single-octet can be used instead: in this case the IC generates an interrupt at every octet ready. The L6364 offers two programmable pins (LED1 and LED2) acting as LED drivers with configurable current capability (up to 8 mA, each).
