NRND9,609 in stock

Overview

The MAX14436FAWE+ is a high-performance, 4-channel digital isolator providing 5000Vrms of galvanic isolation using capacitive coupling technology. It supports data rates up to 200Mbps and features a high common-mode transient immunity (CMTI) of 50kV/us, ensuring reliable data transmission in electrically noisy environments.

Why Choose This Part

This isolator offers extremely low power consumption, drawing only 4.83mA per channel at 50MHz from a 1.89V supply. Its wide operating voltage range from 1.71V to 5.5V allows direct interfacing with modern low-voltage microcontrollers and legacy 5V systems.

Applications

Industrial Fieldbus Systems
Provides high-speed isolation for RS-485, CAN, and PROFIBUS networks in factory automation.
Battery Management Systems (BMS)
Safely isolates high-voltage battery monitoring circuits from low-voltage control logic in EV or energy storage systems.
Medical Equipment
Ensures patient safety by providing 5k Vrms isolation between sensors and processing units.
Isolated SPI Communication
The 200Mbps throughput enables high-speed serial peripheral interface communication across isolation barriers without significant propagation delay.

Getting Started

To evaluate this component, use the MAX14434-MAX14436 evaluation kit which provides a proven PCB layout for high-speed digital isolation. Ensure that 0.1uF bypass capacitors are placed as close as possible to the VDD pins on both sides of the isolation barrier to maintain signal integrity at 200Mbps.
