Description
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. High port count IO-Link master applications are supported through in-band SPI addressing, and the 12MHz SPI interface minimizes host controller access times. In-band addressing and selectable SPI addresses enable cascading up to 16 devices.
The device supports all the IO-Link data rates and features slew-rate-controlled drivers to reduce EMI. The driver is guaranteed to drive up to 300mA (min) load currents. Internal wake-up circuitry automatically determines the correct wake-up polarity, allowing for the use of simple UARTs for wake-up pulse generation.
The MAX14824 is available in a 4mm x 4mm, 24-pin TQFN package with exposed pad, and operates over the extended -40°C to +105°C temperature range.
