Accurate and Versatile: MCA11503 Bidirectional Analog Output Current Sensor

Introducing the MCA11503, a fully integrated bidirectional analog output current sensor designed for high accuracy and versatility. With its exceptional performance and inherent low noise, this current sensor provides precise current measurement in both AC and DC applications.

The MCA11503 features a high bandwidth of 1.5MHz (3dB), ensuring excellent frequency response and fast output response time of 300ns (typical). Its low primary resistance of 0.9 mΩ minimizes power loss and enhances efficiency in current sensing applications.

High Bandwidth and Low Noise: MCA11503 ±5A Current Sensor for Power Applications

Operating with a single 3.3V supply, the MCA11503 exhibits low power consumption of 4.5mA (typical), making it suitable for power-sensitive designs. The device offers a zero current reference pin (Vref) for convenient calibration and overcurrent fault detection for enhanced safety.

Packaged in a RoHS/REACH compliant SOIC-16 package, the MCA11503 is designed to withstand a wide operating temperature range from -40 to +105°C. It is UL/IEC/EN60950-1 certified, ensuring reliability and compliance with stringent safety standards. The device also provides 4.8 kV dielectric strength voltage and 1097 VRMS basic isolation voltage, offering reinforced isolation for added protection.

Ideal for current sense feedback loops in motor control, inverters, power supplies, and other power applications, including those utilizing fast-switching wide bandgap SiC and GaN-based power stages, the MCA11503 delivers accurate and reliable current sensing performance.
