BL0937

The BL0937 is a highly integrated, cost-effective energy metering IC designed for active power measurement in single-phase electrical systems. It supports shunt current sensing and provides accurate active energy measurement with minimal external components. Key features include:
- High Accuracy: Typically ±0.5% error over a dynamic range (1000:1).
- Low Power Consumption: Suitable for energy-efficient applications.
- Digital Output: Delivers frequency pulses proportional to active power (CF pin).
- Wide Voltage Range: Operates at 3.3V or 5V, compatible with most MCUs.
- Tamper Detection: Supports anti-tamper features like reverse current detection.
Commonly used in smart plugs, electricity meters, and IoT energy monitoring, the BL0937 communicates via UART or SPI (varies by model) and complies with international metering standards. Its compact SOP-8 package makes it ideal for space-constrained designs.
For detailed specs, refer to the datasheet from Belling (manufacturer).
