HCPL-0931-000E
Overview
The HCPL-0931-000E is a high-speed, two-channel digital isolator based on Giant Magnetoresistive (GMR) technology. It provides 2500Vrms isolation while supporting data rates up to 110MBd, making it suitable for high-performance signal isolation in harsh environments. The device operates across a 3V to 5.5V supply range and features low power consumption with a typical run current as low as 1.5mA at 3.3V.
Why Choose This Part
The use of GMR technology allows for significantly higher data rates and lower propagation delay compared to traditional optocouplers. It offers excellent 15kV/us common-mode transient immunity and maintains low power consumption, requiring only 2.5mA per channel at 5V operation. Its 3V to 5.5V supply range ensures compatibility with both legacy 5V systems and modern low-voltage microcontrollers.
Applications
Key Specifications
Getting Started
To implement this device, ensure 0.1uF bypass capacitors are placed as close as possible to the VDD1 and VDD2 pins to maintain signal integrity. Because this is a GMR-based isolator, keep high-current magnetic sources away from the IC to avoid interference. The 8-SOIC footprint allows for easy integration onto standard PCBs using standard reflow soldering processes.
