The MAX22512/MAX22522 are mixed signal IO-Link device transceivers 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 MAX2512/MAX22522 integrate programmable analog components including a 13-bit ADC, integrated comparator(s), and four programmable resistors, which allow the MAX22512/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 MAX22512 and MAX22522 are available in a 60-bump WLP package (4.42mm × 2.64mm) and operate over the −40°C to +125°C temperature range.
