MAX14827

IO-Link Device Transceiver

Tiny, Low-Power Dual IO-Link Transceiver


Description

The MAX14827 integrates the high-voltage functions commonly found in industrial sensors, including drivers and regulators. The MAX14827 features two ultra lowpower drivers with active reverse-polarity protection. Operation is specified for normal 24V supply voltages up to 60V. Transient protection is simplified due to high voltage tolerance allowing the use of micro TVS.

The device features a flexible control interface. Pin-control logic inputs allow for operation with switching sensors that do not use a microcontroller. For sensors that use a microcontroller, an SPI interface is available with extensive diagnostics. For IO-Link operation, a three-wire UART interface is provided, allowing interfacing to the microcontroller UART. Finally, a multiplexed UART/SPI option allows using one serial microcontroller interface for shared SPI and UART interfaces.

The device includes on-board 3.3V and 5V linear regulators for low-noise analog/logic supply rails.

The MAX14827 is available in a (4mm × 4mm) 24-pin TQFN package and a (2.5mm × 2.5mm) 25-pin wafer-level package (WLP) and is specified over the extended -40°C to +125°C temperature range.
