The MAX14824 is an IO-Link master interface that integrates an IO-Link physical layer transceiver with an auxiliary digital input and two linear regulators. It supports high port count IO-Link master applications through in-band SPI addressing. The device supports all IO-Link data rates and features slew-rate-controlled drivers to reduce EMI. The driver is guaranteed to drive up to 300mA load currents. The MAX14824 is available in a 4mm x 4mm, 24-pin TQFN package with exposed pad, and operates over the extended -40NC to +105NC temperature range.
The MAX14824 is an IO‑Link master interface that integrates a physical‑layer transceiver, an auxiliary digital input, and two linear regulators. It supports high‑port‑count IO‑Link master applications with in‑band SPI addressing and a 12 MHz SPI interface, allowing cascading of up to 16 devices.
The device is supplied in a 4 mm × 4 mm, 24‑pin TQFN package and operates over a temperature range of –40 °C to +105 °C. Key electrical specifications include a 300 mA driver output capability, 500 mA wake‑up pulse generation, and 5 V/3.3 V linear regulators. Detailed DC and AC electrical characteristics, package thermal data, and ordering information are provided.
