Microchip PAC1921-1-AIA-TR High-Side Power/Current Monitor With Analog Output


Product Description Of PAC1921-1-AIA-TR

PAC1921-1-AIA-TR is a dedicated power-monitoring device with a configurable analog output that can present power, current or voltage. PAC1921-1-AIA-TR is designed for power measurement and diagnostic systems that can not allow for latency when performing high-speed power management. Measurements are accumulated in large lossless registers, allowing for integration periods of 500 μs to 2.9 seconds. The measurement is averaged and presented on the analog output with a full scale range of 3V, 2V, 1 .5V or 1.0V.
