The MAX22522 is a mixed signal IO-Link device transceiver incorporating an ARM^®Cortex-M0 with an IO-Link data link state machine. This state machine autonomously manages all time critical tasks for IO-Link communication at the COM1, COM2, and COM3 data rates. The integrated state machine manages all IO-Link M-sequence types, as well as full ISDU transfers.

The MAX22522 integrates programmable analog components including a 13-bit ADC, an integrated comparator, and four programmable resistors, which allow the MAX22522 to be used for signal generation and conditioning for end-of-line calibration for sensors and actuators.

Low-noise 5V, 3.3V, and 1.8V linear regulators provide low-noise supplies for analog signal sensing. Optionally, an external NPN transistor may also be used to shunt regulator heat off-chip.

The 24V C/Q driver can be configured to operate in high- side (PNP), low-side (NPN), or push-pull (PP) modes. The C/Q current limit threshold is programmable from 50mA to 250mA.

An integrated comparator, a 6-bit DAC, a 13-bit ADC, and high-resolution variable resistors are included for signal conditioning for analog sensing circuitry.

The MAX22522 is available in a 60-bump WLP package (4.42mm × 2.64mm) and operates over the −40°C to +125°C temperature range.

Product Details

The MAX22522 evaluation kit (EV kit) is designed to evaluate the MAX22522 IO-Link device transceiver with integrated Cortex-M0 and analog front end (AFE).

The MAX22522 EV kit includes three integrated regulators (5V, 3.3V, and 1.8V) with a flexible power scheme that allows the device to be used in many different applications. The EV kit is designed to allow the user to test and optimize the power structure for any design.

The MAX22522 EV kit features suite of peripherals for high performance and flexibility. Peripherals include a high-speed comparator, a 6-bit DAC, a 13-bit ADC, four variable resistors, and twelve GPIO pins. All peripherals and associated pins are available on easy-to-access headers.

The MAX22522 EV kit includes two methods to program the IC: using on-board serial EEPROM or programming through the serial debug (SWD) interface. Sample code is available for use with the EV kit and a user can download it from Analog’s website.
