The Sub-μA Current Sensor is a Kinetis K22F based current measurement board running on FreeRTOS and can be used with the Freedom Development Ecosystem or any other Arduino-like development board.
This reference design allows for non-intrusive connection between any MCU and a 3.3V shield and measurement of a wide range of low currents (~60 nA – 5 mA). Multiple communication methods are available, including integration with Freedom Sensor Toolbox (CE).
This reference design introduces PMSM safe motor control software optimized for the dedicated HW HVP-MC3PH-LITE equipped with Kinetis V-series MCUs. The purpose of this reference design is to help customers develop motor control solutions with safety features for controlled heating systems, electric circulation pumps, water installations and other equipment used in industrial applications. The reference design hardware is targeted at circulating pump applications but can be reused in general three-phase motor control applications up to 60 W from 110 V to 230 V AC. The reference design hardware uses NXP's cost-optimized MCU MKV10Z32 with core M0+ and NXP high-voltage DC-DC converter TEA1721. Integrated power modules, surge circuitry, and single-shunt current sensing are also implemented. In the reference design software, sensorless PMSM control with IEC60730/IEC60335 Class B device safety is implemented, including MCU core, memory and peripheral testing, program flow inspection and other safety-related functions. Customers can reuse design reference manuals, schematics, firmware and manufacturing files to accelerate product design.
