Overview

The MAX14930AAWE+ is a four-channel, unidirectional digital isolator designed to provide galvanic isolation between two circuits while allowing digital signals to pass at rates up to 1Mbps. It utilizes capacitive coupling technology to achieve a 2750Vrms isolation rating, protecting sensitive low-voltage microcontrollers from high-voltage transients in industrial environments.

Why Choose This Part

This device offers high CMTI of 25kV/us (Typ), ensuring signal integrity in electrically noisy environments. Its wide-body 16-SOIC package provides the necessary creepage and clearance for reliable safety-rated isolation, while the low 1Mbps data rate is optimized for lower power consumption in slow-speed signaling applications.

Applications

Industrial Fieldbus Isolation
Protects SPI or UART communication lines in PLCs and industrial controllers from ground loops and surges.
Battery Management Systems
Provides high-voltage isolation between battery stack monitors and the main system controller.
Isolated RS-485/RS-232
Separates the transceiver side from the logic side to prevent damage from common-mode voltage differences.
Motor Control Feedback
Safely bridges digital feedback signals from high-voltage motor drivers to low-voltage control logic.

Getting Started

To evaluate this part, use the MAX1493XWEVKIT evaluation kit which allows for testing the throughput and isolation properties of the MAX14930-MAX14936 series. Ensure decoupling capacitors are placed as close as possible to the VDD pins on both sides of the isolator to maintain stability during high-speed switching.
