Microchip Introduces Single-Chip Power Monitoring IC with Measurement Range 0V to 32V

Micro-grid messaging For low-voltage, high-power applications such as field-programmable gate arrays, graphics processing units (GPUs) and embedded computing devices, managing and reducing power consumption is critical. These devices must first accurately measure power consumption. It can be managed, but high-precision power measurement solutions usually mean high cost and require multiple integrated circuits (ICs) or power configurations to measure different tracks. To meet these needs, Microchip Technology Inc. (US Micro Core Technology Inc. introduces new dual- and three-channel power monitoring devices that measure power consumption from 0V to 32V from a single chip, providing designers with an easy-to-use solution that improves power measurement accuracy. The dual channel device is also the industry's first 16-bit native resolution solution for high flexibility over a wide measurement range.

The PAC1932/33 meets the need to measure power through an IC, package multiple channels into a single chip, suitable for point-of-sale (POS) systems, ATM and building automation applications, eliminating the need for efficient measurements from less than 1V in the past. Each component of the 20V voltage rail typically requires multiple components, reducing system cost for the system designer while streamlining the bill of materials (BOM). The PAC1932/33's voltage rail measurement capability from less than 1V to up to 32V also frees development. Staff, eliminating the need to reconfigure measurement resolution between high and low current load events.

As the industry's only dual-channel power measurement device with 16-bit resolution, the PAC1932 can measure 17 minutes without host intervention, allowing developers to measure power and energy without having to adjust the voltage or current range. The device contains two simultaneous measurements A 16-bit analog-to-digital converter (ADC) of voltage and current, which allows developers to obtain real-world power measurements to better design the system for energy efficiency.

Bryan Liddiard, vice president of hybrid and linear products at Microchip, said: 'Because people are constantly looking for ways to reduce application power consumption, high-precision DC power measurement has become a key factor in energy savings. Just as the four-channel PAC1934 improves power measurement for Windows® 10 devices. Efficiency, new dual- and three-channel power-supply monitoring ICs increase power measurement efficiency in low-voltage, high-power applications such as embedded computing and networking applications on the market.
