Communications technology reduces factory downtime

02-11-2020 | Maxim | Design & Manufacture

Modern smart factories must quickly and remotely alter a sensor’s electrical characteristics to reduce downtime and maximise throughput. The MAXREFDES177# IO-Link reference design from Maxim Integrated Products provides the flexibility of the MAX22515 IO-Link transceiver, seamlessly configuring all modes of the MAX22000 software-configurable analog IO. This chipset delivers flexibility with faster reconfiguration to decrease factory downtime.


MAX22000 – the software-configurable analog IO gives up to more than half the power savings and around half the size compared to the nearest competitive solutions on the market. Key functions integrated include a 24-bit ADC analog input mode and an 18-bit DAC analog output mode, as well as operations over a single two-wire interface or a four-wire RTD/thermocouple temperature measurement.


The MAX22515 is claimed to be the industry’s smallest ±1.2kV/500Ohm surge-protected, single-channel IO-Link transceiver. It provides high integration with protection diodes, auxiliary digital input, integrated oscillator, I2C or pin control and selectable 3.3V or 5V LDO which assist to deliver high configurability and decrease SKU. It allows half the power dissipation due to low 2.2Ohm or 2.65Ohm (typ) C/Q driver on-resistance compared to the nearest competitor, in the smallest 2.5mm x 2mm WLP package. It reduces the solution size up to 67% compared to the nearest competitor and fits into small, space-constrained IO-Link sensors or actuators.
