MAX34407 General Description SMBus 4-Channel Wide Dynamic Range
Power Accumulator The MAX34407 is a current and voltage monitor that
is specialized for determining power consumption. The
device has a wide dynamic range to allow it to accurately
measure power in systems that consume small to large
amounts of power. The device is configured and monitored with a standard I2C/SMBus serial interface. The
unidirectional current sensor offers precision high-side
operation with a low full-scale sense voltage. The device
automatically collects the current-sense and voltage
samples. The samples are then multiplied to obtain a
power value and the power values are then accumulated.
Upon a command from the host, the device transfers the
accumulated power samples as well as the accumulation
count to a set of registers that the host can access. This
transfer occurs without missing a sample and allows the
host to retrieve the data not in real time, but at any time
interval. Applications ●● Tablets
