Microchip Unveils 65V Power Monitor for the 48V Power Era
TECHWORLD ·
✦ AI Summary
Microchip Technology released the 65V energy-aware digital power monitors PAC1761 and PAC1861 on the 28th.
The two products offer a 65V measurement range and 75V spike protection, as well as alerts for voltage, current, and power limit violations, step-limiting detection, and cumulative energy threshold-setting functionality.
Microchip identified automobiles, AI and data centers, networking, industrial systems, servers, communications, PoE, and 48V power distribution systems as the main applications for the products.
As power demand rises across automobiles, AI, data centers, networking, and industrial systems, the shift from existing power architectures to 48V-based structures is accelerating. In response, Microchip Technology, which has begun targeting the 48V power systems market, introduced a new 65V digital power monitor as its latest product release.
This shift is also increasing the importance of power monitoring technology. Measuring only voltage and current at a specific point in time is no longer enough, and there is now additional demand for cumulative energy data based on power-status analysis, analysis of energy consumption over time, and responses to changing power environments.
Microchip Technology released PAC1761 and PAC1861 on the 28th. The products are 65V energy-aware digital power monitors designed to identify energy usage patterns based on cumulative power measurement data.
PAC1761 and PAC1861 have a maximum measurement range of 65V and also include 75V spike protection. The 65V measurement range and 75V spike protection provide operating headroom that can handle transient conditions in 48V power systems.
The two products support a programmable alert function that detects voltage, current, and power limit violations. They also provide step-limiting detection for sudden load changes. In addition, both products offer cumulative energy threshold-setting functionality.
Based on these functions, users can monitor both the system's instantaneous power status and long-term energy consumption patterns at the same time. The company said this makes it possible to respond proactively to power changes.
Keith Pazul, vice president of Microchip's Mixed-Signal Linear business unit, said the industry's focus is shifting away from measuring power at a specific moment and toward understanding and responding to energy behavior across the entire system and product lifecycle. He said the PAC1761 and PAC1861 product family can measure instantaneous conditions while also tracking energy consumption and availability over time.
Keith Pazul said the product family helps customers build 48V systems with higher performance and reliability. He added that it offers scalable low-power solutions and pin-compatible package options. He also cited reduced monitoring overhead, lower design risk, and improved supply flexibility as benefits.
PAC1761 is a 12-bit digital power monitor, while PAC1861 is a 16-bit digital power monitor. The common packages for PAC1761 and PAC1861 are VDFN-8 (similar to SOT23-8), VDFN-10, and MSOP-10, and both products also offer automotive ordering options.
Using pin-compatible options, the products can be switched to other devices when requirements, cost, performance, or supply availability change. This can reduce the burden of design changes, and the use of pin-compatible options is also presented as a way to shorten certification cycles.
Microchip identified automobiles, AI and data centers, networking, industrial systems, servers, communications, PoE (power over Ethernet), and 48V power distribution systems as the main applications for PAC1761 and PAC1861.
