MAX14824 IO-Link Master Transceiver General Description Benefits and Features The MAX14824 is an IO-Link master interface that IO-Link v.1.0 and v.1.1 Physical Layer Compliant integrates an IO-Link physical layer transceiver with an Supports COM1, COM2, and COM3 Data Rates auxiliary digital input and two linear regulators. High port Push-Pull, High-Side, or Low-Side Outputs count IO-Link master applications are supported through in-band SPI addressing, and the 12MHz SPI interface 300mA C/Q Output Drive minimizes host controller access times. In-band address- 1F C/Q Load Drive Capability ing and selectable SPI addresses enable cascading up to Generates 500mA Wake-Up Pulse 16 devices. Automatic Wake-Up Pulse Polarity The device supports all the IO-Link data rates and fea- Auxiliary Digital Input tures slew-rate-controlled drivers to reduce EMI. The driver is guaranteed to drive up to 300mA (min) load cur- 5V and 3.3V Linear Regulators rents. Internal wake-up circuitry automatically determines SPI Interface for Configuration and Monitoring the correct wake-up polarity, allowing for the use of simple SPI-Based Chip Addressing UARTs for wake-up pulse generation. EMI Emission Control Through Slew-Controlled The MAX14824 is available in a 4mm x 4mm, 24-pin Driver TQFN package with exposed pad, and operates over the extended -40C to +105C temperature range.
