MAX44298 Current and Voltage Sense with Power Measurement General Description The MAX44298 is a low-side current, voltage, and power monitoring circuit that provides an analog output current proportional to the measured current, voltage, and the internally calculated instantaneous power. Instantaneous power is calculated internally by multiplying the load current and a fraction of the load voltage set by an external resistive divider. All three outputs are scaled to a full-scale current of either 100µA or 50µA. This full-scale current option is set with a simple pin-strap, ISET.
