Future Electronics – Faraday Development Board
Faraday Current Sense and Measurement Solution designed by our very own System Design Center!
Faraday is a simple platform designed by Future Electronics System Design Center to demonstrate current sensing designs. It implements four channels with current sensors controlled by two Infineon PSoC 4 (CY8C4245) microcontrollers to measure voltage, current and power.
Channel 1 and 2 are isolated channels implemented with two Melexis integrated magnetic current sensors (MLX91220) controlled by Infineon PSoC 4 (CY8C4245) (marked as PSoC-A on block diagram) to measure DC current up to 25A / 60V via terminal block connections.
Channel 3 is designed for current measurement up to 5A / 20V via an USB Type C port connection, using Vishay current sense resistor (WSL series) combined with Diodes Inc. current monitor (ZXCT1086) and Infineon PSoC 4 (CY8C4245) microcontroller (PSoC-B on block diagram).
Channel 4 can measure up to 300mA / 5V via a USB Type A port connection using the same PSoC-B microcontroller as channel 3.
The PSoC-A is also controlling the communication to PC through USB/UART bridge (CY7C65213). And the PSoC-B controls user interface with capacitive touch keypad user buttons and the WiseChip OLED display to show current, voltage and power measurement results.
