USB Isolation Module ADUM3160 2500V Isolation 1.5Mbps/12Mbps Low/Full Speed -40°C to +105°C Compatible with STM32 LabVIEW MATLAB
1. Product Parameters Isolation Voltage: 2500V RMS (UL 1577 Certified) Data Rates: Low Speed (1.5Mbps), Full Speed (12Mbps) Operating Voltage: 4.5V-5.5V DC (VBUS Powered) Supply Current: 7mA (Max @1.5Mbps), 8mA (Max @12Mbps) ESD Protection: ±8kV (IEC 61000-4-2 Contact Discharge) CMTI: >25kV/μs (Common-Mode Transient Immunity) Isolation Technology: ADI iCoupler Magnetic Coupling USB Ports: Type-A Female (Output), Type-B Female (Input) Operating Temperature: -40°C to +105°C Protection: Upstream Short-Circuit, Overvoltage Lockout Compliance: USB 2.0, RoHS, Automotive Grade 2. Pin Functions VBUS1: Input Power (4.5V-5.5V DC), Connects to Host VBUS GND1: Input Ground (Host Side Reference) D+1/D-1: Host-Side Data Lines (Bidirectional Differential Pair) VBUS2: Output Power (Isolated 5V DC), Connects to Peripheral VBUS GND2: Output Ground (Peripheral Side Isolated Reference) D+2/D-2: Peripheral-Side Data Lines 3. Frequently Asked Questions Q1: Does this support USB 3.0 or high- speed (480Mbps) devices? A1: No. Only USB 2.0 Low/Full Speed (1.5Mbps/12Mbps) devices are compatible (e.g., keyboards, mice, serial adapters) . Q2: Can it be hot-plugged during operation? A2: Yes. Supports USB hot-swapping without host reboot. Ensure input voltage (VBUS1) is stable before peripheral connection . Q3: Why does my PC fail to detect the peripheral after installation? A3: Check: ① VBUS1 voltage ≥4.5V (use regulated 5V power); ② Peripheral draws <100mA current (isolator max output: 180mA); ③ No pin misalignment (GND1/GND2 must be correctly referenced) .
