The PAC1710 is a high-side bi-directional current sensing monitor with precision voltage measurement capabilities. The power monitor measures the voltage developed across an external sense resistor to represent the high-side current of a battery or voltage regulator. The PAC1710 also measures the SENSE+ pin voltage and calculates average power over the integration period. The PAC1710 can be programmed to assert the ALERT# pin when high and low limits are exceeded for Current Sense and Bus Voltage. Available in a RoHS compliant 3 X 3mm 10-pin DFN package.
