Microchip Technology PAC1761 12-Bit Single-Channel Power Monitor
Microchip Technology PAC1761 12-Bit Single-Channel Power Monitor is a 65V energy-aware digital power monitor that makes 48V power architectures more efficient and resilient. This monitor combines various power-measurement insights with high-voltage measurement and transient spike protection capabilities. The growing adoption of 48V power architectures is increasing demand for digital power monitors that support measurements up to 65V and provide 75V spike protection. Designed to meet these requirements, the PAC1761 understands and responds to energy usage dynamics in real time using accumulated power measurement data. Additional features include programmable alerts for voltage, current, and power excursions, step-limit detection to flag sudden load changes, and configurable accumulated energy thresholds. Microchip Technology PAC1761 Single-Channel Power Monitor is ideal for automotive, AI/data center, networking, industrial, Power over Ethernet (PoE), and 48V power distribution systems.
