Highly linear output voltage proportional to AC/DC current
Built-in galvanic isolation for safe current sensing
Compact SOIC8 surface-mount package for streamlined PCB design
Factory-trimmed for accuracy with minimal external components
Measures up to ±20A with a high 2.1 kΩ internal resistance
Automotive: Current monitoring in electric vehicles
Industrial: Motor control and load detection
Consumer Electronics: Battery management systems
Power Supply Systems: Inverters and chargers
Renewable Energy: Solar energy charge controllers
Smart Home Devices: Protection for monitoring circuits
Ensure input current does not exceed the ±20A maximum rating to prevent sensor damage.
Maintain appropriate voltage supply (4.5V to 5.5V) for stable operation.
Ensure proper PCB layout to minimize noise interference in high-frequency applications.
Use bypass capacitors (e.g., 0.1 µF) close to the power supply pins for noise suppression.
The sensing trace should be routed to minimize magnetic field interference from nearby components.
Q: What happens if the current exceeds 20A?
A: The sensor may saturate or be permanently damaged if the rating is exceeded.
Q: Does this sensor work for both AC and DC current?
A: Yes, it is specifically designed to measure both AC and DC current.
Q: How accurate is the output voltage?
A: Accuracy is typically ±1.5% at room temperature, and performance may vary with temperature.
Q: Can this sensor measure very low currents (e.g., below 1A)?
A: It can, but the sensitivity might make it less optimal for precise low-current measurements.
