Description

EVALUATION BOARD CURRENT/POWER MONITOR
The PAC1921 is a dedicated power-monitoring device with a configurable analog output that can present power, current or voltage. The PAC1921 is designed for power measurement and diagnostic systems that cannot allow for latency when performing high-speed power management. Measurements are accumulated in large lossless registers, allowing for integration periods of 500 ┬Ás 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. The PAC1921 has a READ/INT pin for host control of the measurement integration period. This pin can be used to synchronize readings of multiple buses between several devices. Alternatively, PAC1921 is able to provide outputs in a free-running mode. Information is provided on the OUT pin and is available via SMBus if desired. Data sampling and output attributes, such as the internal ADC resolution (11-bit or 14-bit) and sample rate, are configurable. The SMBus interface has more selections for user-configurable options. The PAC1921 is a 1% accurate power measurement device that measures and cancels the zero offset from the input pins. The PAC1921 was designed to monitor power rails from 0-32V with a full-scale capability of 100 mV across the sense resistor. No input filters are required for this device.
