Dual-channel transceiver IC brings more flexibility to Single-Input/Output and IO-Link sensor applications
The L6364 transceiver features dual communication channels, which allow configurable output doubling for extra drive strength, in addition to a DC/DC converter and dual-mode UART.
The L6364 is a monolithic device, which can drive capacitive, resistive, or inductive loads.
Compliant with IO-Link specification v1.1, the L6364 supports IO-Link at COM2 (38.4 Kbaud) and COM3 (230.4 Kbaud) modes, and also standard Single-Input/Output (SIO) communication. The dual outputs, which contain an IO-Link CQ pin and standard DIO pin, each have surge-pulse and reverse-polarity protection. The maximum drive strength is programmable up to 250mA and the two channels can be paralleled to supply up to 500mA.
An SPI port connects the L6364 to the host microcontroller (MCU), with an additional interrupt pin for diagnostic reporting. The MCU can exchange sensor data through the UART or by using single-byte or multi-byte (SPI) modes. The integrated UART supports IO-Link message sequencing (M-Sequencing). It can be programmed to operate in IO-Link or standard SIO mode and allows unlimited M-Sequence size in single-octet IO-Link. An internal data buffer supports up to 15 octets.
Key features of L6364

Application examples
The L6364 device is perfectly suitable for any IO-Link application connecting sensors and actuators, which either require two separate point-to-point, bi-directional communication channels, or need to double the output current with the two channels in parallel.
