The BL0937B is a single-phase multi-function energy meter IC from Shanghai Belling, suitable for applications like smart appliances and power sockets. It boasts high accuracy, with less than ±0.5% error over a dynamic range of 2500:1.
This IC integrates high-accuracy Sigma-Delta ADCs, a voltage reference, and power management circuitry to calculate active power, current RMS, and voltage RMS. It features an on-chip oscillator for clock source and operates on a single 3.3V supply with low power consumption (8 mW typical).
The BL0937B provides high-frequency pulse outputs for energy metering (CF) and for indicating RMS values (CF1). It supports a current measurement range from 8mA to 30A and includes on-chip anti-creep protection and a power supply detector. The device is available in a SOP8 package.
Key electrical specifications include a typical voltage reference of 1.1V and a supply voltage range of 3.0V to 3.6V. The current channel input signal range is ±50mVpp, and the voltage channel input signal range is ±200mVpp.
