Maxim Introduces the IO-Link Physical-Layer Transceiver for IO-Link Sensor Applications

Maxim Integrated Products has announced that it has launched the MAX 14821, which is the smallest IO-Link physical layer transceiver. The product comes in the size of 2.5 X 2.5 mm WLP, which enables in saving 60% space and ideal for fitting in any kind of housing.

The IO-Link protocol enables end-to-end communication between sensors and actuators and master control modules. It can also calibrate, diagnose and transmit data by using three conductor wires and connectors. The protocol can support all IO-Link data rates such as 4.8 Kbps, 38.4 Kbps and 230.4 Kbps and binary sensor and actuator applications of 24 V.

The MAX 14821 comes with two drivers. The C/Q line driver can be adjusted for a push-pull, high or low side output stage. The DO driver can also be configured like the C/Q line driver. This feature makes the protocol ideal for integration into any system and it can have an interface with a wide range of sensors. The protocol has a maximum speed of 12 MHz and for control and monitoring purposes it also has a SPI interface. The protocol also has linear regulators of 5 V and 3.3 V integrated in order to offer more flexibility in design. Other features include thermal protection, reverse voltage protection, and short-circuit protection and monitoring of low voltage. The protocol can operate at temperatures of -40°C to +85°C and is also available in a size of 4 X 4 mm with TQFN package. While samples of the product are now available with the company, large scale production of the same will take 10 to 12 weeks.
