Microchip power monitoring ics increase the power measurement accuracy of Win10 software to 99%

     Microchip Technology announced the launch of PAC1934, a high-precision power and energy monitoring chip that is fully compatible with the Energy Estimation Engine (E3) built into the Windows 10 operating system. On battery-powered Windows10 devices, the measurement accuracy is up to 99%. Microchip's PAC 1934 and Windows 10 drivers, combined with Microsoft's E3 service, improved battery usage measurement accuracy by 29 percent for various software applications.

     Jessie Labayen, principal program manager at Microsoft, said: "Microchip's PAC1934 has a very wide measurement range and can measure displays, cpus, and memory with high precision power consumption of storage, network, overall, and other system components. This is a major improvement to the software evaluation capabilities of Windows 10 Energy Estimate |, and a big step forward for system providers and everyday users.

     The PAC1934 is designed to measure the minimum 0V and maximum 32V voltage rails. Thanks to this capability, the chip can accurately measure a wide range of power consumption, from simple core processing unit (CPU) tasks to software running on devices connected via USB Type-CTM connectors. The PAC1934 is a four-channel device with 16-bit power measurement and a 17-minute summation register, ideal for determining power and energy usage without adjusting voltage or current ranges.

     Bryan Liddiard, Microchip's vice president of marketing for Mixed Signal and Linear Products, said: "Windows 10 devices require accurate and easy-to-use power monitoring ics to display the most accurate information about software power consumption. Consumers don't necessarily know that Microchip is behind the scenes providing support, but thanks to this new device, people around the world will have more reliable battery life statistics.

     The capabilities of this device make it an indispensable component of future software updates. Support for two-way measurement means that you can measure battery charging and discharging at the same time, and it is very suitable for the upcoming USB Type-C charging topology, which will be widely used. In addition, the device can be used as a standard high-voltage side current sensor for server, networking, automotive, and industrial applications. Microchip is also actively working to support PAC1934 in a variety of applications in Lux.
