MAX14829

Low Power IO-Link Device Transceiver with Dual Drivers

Tiny, Pin Controlled Low-Power Dual IO-Link Transceiver


Please check latest availability status for a specific part variant.

Description

The MAX14829 integrates the high-voltage functions commonly found in industrial sensors. The MAX14829 features two ultra low-power drivers with active reversepolarity protection and is specified for operation with supply voltages from 9V to 60V. The high-voltage tolerance of the MAX14829 allows for the use of micro-TVS, simplifying transient protection.

Pins are used to configure and monitor the device. Driver overload and supply monitor outputs are available. Pin-control allows for operation with switching sensors that do not use a microcontroller.

Two integrated linear regulators (3.3V and 5V) provide low-noise analog and logic supply rails for the device or external circuits.

The MAX14829 is available in a (4mm x 4mm) 24-pin TQFN package and is specified over the extended -40°C to +125°C temperature range.
