MAX14827A
Low-Power, Ultra-Small, Dual Driver,
IO-Link Device Transceiver
General Description
The MAX14827A integrates the high-voltage functions
commonly found in industrial sensors, including drivers
and regulators. The MAX14827A features two ultra low-
power 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 MAX14827A is available in a (4mm x 4mm) 24-pin
TQFN package and a (2.5mm x 2.5mm) 25-pin wafer-
level package (WLP) and is specified over the extended
-40°C to +125°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
