2.6 seconds 10-Lead 3 x 3 mm VDFN package The PAC1710/20 are single and dual high-side
bidirectional current sensing monitors with precision
voltage measurement capabilities. Each sensor
measures the voltage developed across an external
sense resistor to represent the high-side current of a
battery or voltage regulator. The PAC1710/20 also
measures the SENSE+ pin voltage and calculates …
