Maxim Integrated's IO-Link Communications Technology Reduces Factory Downtime
Intelligence at the edge simplifies equipment reconfiguration and commissioning of sensors
Modern smart factories need to quickly and remotely adjust a sensor's electrical characteristics to minimize downtime and maximize throughput. The MAXREFDES177# IO-Link® reference design from Maxim Integrated Products, Inc. demonstrates the flexibility of the MAX22515 IO-Link transceiver, seamlessly configuring all modes of the MAX22000 software-configurable analog IO. This chipset provides flexibility with faster reconfiguration to reduce factory downtime.
Maxim Integrated's chipset solution of MAX22000 and MAX22515 builds upon the benefits of IO-Link's two-way universal interface. The IO-Link interface allows every IO-Link sensor, actuator or IO expansion module to be interchangeable to a standard hardware interface. It also provides software-defined performance parameters and selectable analog input or output performance modes. These software-selectable capabilities are combined and demonstrated in the MAXREFDES177# IO-Link reference design.
IO-Link & Software-Configurable IO Products:
MAX22000: The software-configurable analog IO provides up to more than half the power savings and approximately half the size compared to the closest 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 either a single 2-wire interface or a 4-wire resistance temperature detector (RTD)/thermocouple temperature measurement.
MAX22515: The MAX22515 is the industry's smallest ±1.2 kV/500 Ω surge-protected, single-channel IO-Link transceiver. It features high integration with protection diodes, auxiliary digital input, I²C or pin control, integrated oscillator and selectable 3.3 V or 5 V LDO which help to provide high configurability and reduce SKU. It enables half the power dissipation due to low 2.2 Ω or 2.65 Ω (typ) C/Q driver on-resistance compared to the closest competitor, in the smallest 2.5 mm × 2.0 mm WLP package. It cuts the solution size up to 67 percent compared to the closest competitor and fits into small, space-constrained IO-Link sensors or actuators.
