Visão Geral
Description
### Key Features:
- AEC-Q100 qualified for automotive use.
- Low power consumption with 1.8V to 5.5V supply range.
- Default output options (high or low) for fail-safe operation.
- CMTI (Common-Mode Transient Immunity): >100 kV/µs.
- Wide temperature range: -40°C to +125°C.
### Applications:
- Automotive systems (CAN, LIN, SPI, I²C isolation).
- Industrial controls, motor drives, and power supplies.
The ISO7220AQDRQ1 ensures signal integrity while protecting sensitive circuits from high-voltage transients, making it ideal for harsh environments.
Equivalent
- ISO7220AQDWRQ1 (same specs, different package)
- ISO7220AD (non-automotive grade)
- Si8621BB-B-IS (Silicon Labs)
- ADuM1201ARZ (Analog Devices)
- MAX14930AWE+ (Maxim Integrated)
These alternatives offer similar dual-channel isolation with comparable speed and voltage ratings. Verify specs for exact compatibility.
Features
- High-speed operation: Supports data rates up to 150 Mbps per channel.
- Low power consumption: Typically 1.7 mA per channel at 1 Mbps.
- Wide voltage range: 2.7V to 5.5V on both sides (VCC1 & VCC2).
- High isolation: 4000 VPK (UL 1577) and 2500 VRMS (IEC 60747-5-5).
- AEC-Q100 qualified: Suitable for automotive applications (Grade 1, -40°C to +125°C).
- Default output options: High (ISO7220A) or Low (ISO7220B) when input is unpowered.
- Low propagation delay: 11 ns typical for fast signal integrity.
- CMTI: 25 kV/µs (min) for robust noise immunity.
- Package: 8-pin SOIC (D) for compact designs.
Ideal for CAN, SPI, I²C, and GPIO isolation in automotive and industrial systems.
Application
1. Automotive Systems: Used in electric vehicles (EVs), battery management systems (BMS), and powertrain controls for signal isolation.
2. Industrial Automation: Isolates communication in PLCs, motor drives, and sensors to prevent noise interference.
3. Medical Equipment: Ensures safety in patient-monitoring devices by isolating sensitive signals.
4. Renewable Energy: Protects control signals in solar inverters and wind turbines.
It meets AEC-Q100 standards, ensuring reliability in harsh environments.
