MAX14828 Low-Power, Ultra-Small IO-Link Device Transceiver General Description Benefits and Features The MAX14828 integrates the high-voltage functions Low Power Dissipation for Small Sensors commonly found in industrial sensors. The MAX14828 1.2 (typ) Driver On-Resistance features one ultra low-power driver (C/Q) with active 50mW (typ) Power Dissipation When Driving reverse-polarity protection. An auxiliary digital input is 100mA Load provided to allow firmware updates through a UART High Configurability and Integration Reduce SKUs interface. Transient protection is simplified due to high Auxiliary 24V Digital Input voltage tolerance allowing the use of micro TVS. Selectable Driver Current: 50mA to 250mA The device features a flexible control interface. Pin-control SPI or Pin-Control Interface for Configuration and logic inputs allow for operation with switching sensors Monitoring that do not use a microcontroller. For sensors that use a Multiplexed SPI/UART Interface Option microcontroller, an SPI interface is available with extensive 5V and 3.3V Linear Regulators diagnostics. For IO-Link operation, a UART interface is Optional External Transistor Supports Higher provided, allowing interfacing to the microcontroller UART. Regulator Loads Finally, a multiplexed UART/SPI option allows using one Integrated LED Drivers serial microcontroller interface for shared SPI and UART Pin and Software Compatible to MAX14827A interfaces. Robust Communication The device includes on-board 3.3V and 5V linear 65V Absolute Maximum Ratings on Interface and regulators for low-noise analog/logic supply rails. Supply Pins Allows for Flexible TVS Protection The MAX14828 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) wafer-level Noise Thermal Shutdown package (WLP) and is specified over the extended -40C to +125C temperature range.
