July 19, 2018 —Microchip Technology introduced two- and three-channel power monitoring devices that measure from 0V to 32V on a single chip. The two-channel device has native 16-bit resolution.
The PAC1932/33 devices include what is needed to measure power on a single Integrated Circuit (IC), integrating multiple channels in a single package for applications such as Point of Sale (POS) systems, ATMs and building automation. The devices’ ability to measure voltage rails under 1V to as high as 32V also relieves developers from having to reconfigure measurement resolution between low and high current load events.
As a two-channel device with 16-bit power measurement, the PAC1932 can measure without host intervention for 17 minutes, relieving developers from adjusting voltage or current range to measure power and energy. The devices include two 16-bit Analog-to-Digital Converters (ADCs) that can measure voltage and current simultaneously, enabling developers to extract a true power measurement.
The PAC1932/33 work in conjunction with Linux and Windows 10 software drivers. The PAC1932/33 is register-compatible with the ADM00805 evaluation board, which can be used to start development with a graphical user interface reporting VSENSE, VBUS, power and accumulated power.
