on all battery-powered Windows 10 devices. Combining Microchip's PAC1934 and the Windows 10 driver with Microsoft's E3 service can improve battery usage measurements by various software applications by up to 29 percent.
The PAC1934 is designed to measure voltages from 0V to 32V. This capability allows it to accurately measure power usage, from simple CPU (Core Processing Unit) tasks to software execution on devices connected via a USB Type-C™ connector. The PAC1934 is a four-channel device with 16-bit power measurement and a 17-minute record and accumulation, making it ideal for determining power consumption and usage without the need to adjust the voltage and current range.
The device has capabilities that will also allow for future software updates. Thanks to its bidirectional measurement and its ability to measure battery charging and discharging, the PAC1934 is well-suited for upcoming USB Type-C charging topologies as they develop and become more widespread. In addition, the device functions as a standard high-side current sensor for applications in servers, networks, automotive, and industrial settings. Microchip is also actively working to make the PAC1934 compatible with Linux in various applications.
The PAC1934 power monitoring IC is now available for sampling and volume production.
