MAX14827A Low-Power, Ultra-Small, Dual Driver, IO-Link Device Transceiver General Description Benefits and Features The MAX14827A integrates the high-voltage functions Low Power Dissipation for Small Sensors commonly found in industrial sensors, including driv- 2.3/2.7 (typ) Driver On-Resistance ers and regulators. The MAX14827A features two ultra 70mW (typ) Power Dissipation at 100mA (When low-power drivers with active reverse-polarity protection. Both C/Q and DO Drivers Are Driving) Operation is specified for normal 24V supply voltages up High Configurability and Integration Reduce SKUs Auxiliary 24V Digital Output and Input to 60V. Transient protection is simplified due to high volt- age tolerance allowing the use of micro TVS. Selectable Driver Current: 50mA to 250mA SPI/Pin-Control Interface for Configuration and The device features a flexible control interface. Pin- Monitoring control logic inputs allow for operation with switching sen- Multiplexed SPI/UART Interface Option sors that do not use a microcontroller. For sensors that 5V and 3.3V Linear Regulators use a microcontroller, an SPI interface is available with Optional External Transistor Supports Higher extensive diagnostics. For IO-Link operation, a three-wire Regulator Load Capability UART interface is provided, allowing interfacing to the Integrated LED Driver microcontroller UART. Finally, a multiplexed UART/SPI option allows using one serial microcontroller interface for Selectable Driver Integrated Protection Enables shared SPI and UART interfaces. Robust Communication The device includes on-board 3.3V and 5V linear regula- 65V Absolute Maximum Ratings on Interface and Supply Pins Allows for Flexible TVS Protection tors for low-noise analog/logic supply rails. 9V to 60V Specified Operation The MAX14827A is available in a (4mm x 4mm) 24-pin Glitch Filters for Improved Burst Resilience and TQFN package and a (2.5mm x 2.5mm) 25-pin wafer- Noise level package (WLP) and is specified over the extended Thermal Shutdown Auto-Retry Cycling -40C to +125C temperature range.
