Description

Please see the MAX14827A for our recommended replacement.The MAX14827 integrates the high-voltage functionscommonly found in industrial sensors, including driversand regulators. The MAX14827 features two ultra lowpowerdrivers with active reverse-polarity protection.Operation is specified for normal 24V supply voltagesup to 60V. Transient protection is simplified due to highvoltage tolerance allowing the use of micro TVS.The device features a flexible control interface. Pin-controllogic inputs allow for operation with switchingsensors that do not use a microcontroller. For sensors thatuse a microcontroller, an SPI interface is available withextensive diagnostics. For IO-Link operation, a three-wireUART interface is provided, allowing interfacing to themicrocontroller UART. Finally, a multiplexed UART/SPIoption allows using one serial microcontroller interface forshared SPI and UART interfaces.The device includes on-board 3.3V and 5V linearregulators for low-noise analog/logic supply rails.The MAX14827 is available in a (4mm × 4mm) 24-pinTQFN package and a (2.5mm × 2.5mm) 25-pin wafer-levelpackage (WLP) and is specified over the extended-40°C to +125°C temperature range.ApplicationsIndustrial SensorsIO-Link Sensors and ActuatorsSafety Applications
