Reduce Costs and Bill of Materials with Single Power Monitoring IC that Measures Power from 0V to 32V
July 19 2018 - 8:00AM
Managing and reducing power consumption is crucial in low-voltage,
high-power applications such as Field-Programmable Gate Arrays
(FPGAs), Graphics Processing Units (GPUs) and embedded computing
devices. These devices must first accurately measure power before
they can manage it, but precision power measurement solutions are
often costly and require multiple ICs or power configurations to
measure different rails. To meet these needs, Microchip Technology
Inc. (NASDAQ:MCHP) today introduced new two- and three-channel
power monitoring devices that measure from 0V to 32V on a single
chip, offering designers solutions that are easy to adopt and
improve power measurement accuracy. The two-channel device is also
the industry’s first with native 16-bit resolution, providing
leading flexibility across a wide measurement range.
The PAC1932/33 devices include precisely 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. This
reduces costs for system designers while also consolidating their
Bill of Materials (BOM), as the measurement of sub 1V to 20V
voltage rails normally require separate components to measure each
rail efficiently. 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 the industry’s only 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. As a result, developers can better design systems to
efficiently save power.
“As applications continue to seek ways to reduce power
consumption, precision DC power measurement has grown as a key
element for energy savings,” said Bryan Liddiard, vice president of
Microchip’s Mixed Signal and Linear Division. “Just as the
four-channel PAC1934 improved power measurement for Windows 10
devices, the new two- and three-channel power monitoring ICs offer
improved power measurement for low-voltage, high-power applications
in markets such as embedded computing and networking.”For more

Development ToolsThe 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.
Pricing and AvailabilityThe two-channel PAC1932
power monitoring IC is available now for sampling and in volume
production starting at $0.78 each in 10,000-unit quantities. The
three-channel PAC1933 power monitoring IC is available now for
sampling and in volume production starting at $0.94 each in
10,000-unit quantities.
