PAC1921 High-Side Power/Current Monitor with Analog Output Features Description Configurable Measurement Type Output: Power, The PAC1921 is a dedicated power-monitoring device Current or Bus Voltage with a configurable analog output that can present power, current or voltage. The PAC1921 is designed for Configurable Voltage Output (3V, 2V, 1.5V, 1V) power measurement and diagnostic systems that can- - All output values also available over SMBus not allow for latency when performing high-speed New Device Topology power management. Measurements are accumulated - Provides integrated average power in large lossless registers, allowing for integration peri- measurement ods of 500 s to 2.9 seconds. The measurement is - Power measurements provided to averaged and presented on the analog output with a microcontroller with ADC inputs full scale range of 3V, 2V, 1.5V or 1.0V. - Unique lossless integrating architecture The PAC1921 has a READ/INT pin for host control of the allows operation at low sense voltages measurement integration period. This pin can be used to - Output voltage proportional to selected synchronize readings of multiple buses between several measurement devices. Alternatively, PAC1921 is able to provide out- puts in a free-running mode. Information is provided on High-Side Current Sensor the OUT pin and is available via SMBus if desired.
