PAC1761T-3E/E3
Microchip TechnologyThe PAC1761 is a single-channel digital power monitor that measures bus voltage and bidirectional current up to 65 V, with 75 V spike protection for the transients common on 48 V distribution. Its 12-bit converter works across a 100 mV full-scale sense range (configurable to 50 mV) with 1% power measurement accuracy, and an on-chip 32-bit accumulator supports power integration and coulomb counting, so the host gets energy and charge data without constant polling. Quiescent current is 90 uA at 1024 samples per second, and the SMBus 3.1 / I2C interface runs Fast Mode Plus and 3.4 Mbps High Speed Mode, with programmable alerts and step-limit detection for sudden load changes. This -3E/E3 code is the MSOP-10 version; the pin-compatible 16-bit PAC1861 fits the same footprint where finer resolution is required. Parameters verified against Microchip Technology documentation.
