The The MikroElektronika's PAC1720 Click is a compact add on board that contains an energy monitoring solution. This board features the PAC1720, an I2C configurable dual high side bidirectional current sensing monitor with precision voltage measurement capabilities from Microchip Technology. The PAC1720 measures the voltage developed across external sense resistors to represent the high side current of a battery or voltage regulator. They also measure the SENSE+ pin voltage and use these estimated values to present a proportional average power calculation. The current sensing feature includes fault protection, where during a fault condition, the ALERT pin can be asserted or masked. This Click board performs power calculations enabling energy monitoring in industrial and embedded applications, power management systems, and many more.
