Introduction
ADM2682EBRIZ - Protecting Sensitive Circuitry from Voltage Transients and Ground Loops
Core Functions
- Implements isolated RS-485/RS-422 communication with 2.5kVrms galvanic isolation, protecting sensitive circuitry from voltage transients and ground loops.
- Features integrated surge protection (±15kV ESD contact discharge, ±25kV air discharge) to enhance system reliability in harsh industrial environments.
- Supports data rates up to 50Mbps for high-speed serial communication, balancing performance and power efficiency.
- Incorporates a low-dropout (LDO) regulator and isolated power supply, eliminating the need for external isolated power components and reducing BOM cost.
- Offers half-duplex operation with automatic direction control (ADC) option, simplifying circuit design and reducing MCU GPIO usage.
Key Applications
- Industrial Control Systems: Enables reliable data transmission between PLCs, sensors, and HMIs in factory automation lines and process control systems.
- Smart Grid Equipment: Facilitates communication in power meters, distribution terminals, and substation monitoring devices with strong anti-interference capability.
- Building Automation: Connects HVAC systems, lighting controllers, and access control devices in intelligent buildings via long-distance RS-485 bus.
- Medical Equipment: Provides isolated communication for patient monitoring devices, diagnostic instruments, and laboratory equipment to ensure safety and signal integrity.
- Transportation Electronics: Supports data exchange in automotive diagnostics, railway signaling systems, and electric vehicle charging stations with robust surge protection.
