Description

The MAX14828 integrates the high-voltage functions commonly found in industrial sensors. The MAX14828 features one ultra low-power driver (C/Q) with active reverse-polarity protection. An auxiliary digital input is provided to allow firmware updates through a UART interface. 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 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 MAX14828 is available in a (4mm x 4mm) 24-pin TQFN package and a (2.5mm x 2.5mm) wafer-level package (WLP) and is specified over the extended -40°C to +125°C temperature range.
