About this product
The BL0939 is a calibration-free single-phase energy metering IC with a built-in clock. It uses three Sigma-Delta ADCs to measure two currents and one voltage at the same time, and reports RMS current, RMS voltage, active power and energy. It suits smart sockets, energy meters and home appliances, with data output over UART or SPI.

Frequently asked questions
What is the price of BL0939 Single-Phase Energy Metering IC SOP-16 in Egypt?
BL0939 Single-Phase Energy Metering IC SOP-16 currently costs 125 EGP in Egypt.
Where can I buy BL0939 Single-Phase Energy Metering IC SOP-16 in Egypt?
BL0939 Single-Phase Energy Metering IC SOP-16 is available from UGE. Compare the offers above to find the best price.
Can it measure two currents at the same time?
Yes. It has two current channels and one voltage channel sampled simultaneously, which lets it monitor leakage current alongside the main load. Mains-connected designs need proper isolation and creepage design.
Which microcontroller can read its data?
The output is available over UART or SPI, so it can be read by Arduino, ESP32, STM32 or Raspberry Pi boards. Make sure the logic levels of the IC and the microcontroller match.
