STPMC1 Overview
Key Features
- The calculator has five input data pins
- The first three receive the voltage and current information of the phases
- In fact, each data input processes two ΔΣ signals, multiplexed in time and generated by the STPMSx device
- The fifth input data pin accepts non-multiplexed ΔΣ signals and it can be used for sensing the magnetic field information from a Hall sensor
- This allows the achievement of very high computation precision with fast and efficient digital architecture
- All the data recorded by the STPMC1 are accessible through an SPI port, which is also used to configure and calibrate the device
- The configuration and calibration data can be saved in a 112-bit OTP block, or dynamically set in microprocessor-based meters
