Description
This verified design can accurately measure current across a range of 30 A on a bus that carries up to 36-V common mode voltage over a range of -40°C to +85°C. This design can measure current from 0 A to 30 A with a grounded reference or -30 A to 0 A with a 16-V reference. The design sums the output of two INA250A2 devices and generates a ground-referenced output voltage. The INA250 is a voltage-output, current-sensing amplifier family that integrates an internal shunt resistor to enable high-accuracy current measurements.
Features
• Compact layout with good thermal properties
• 30A Sustained current measurement with parallel integrated shunt current sense amplifiers
• Able to configure for full-range positive, full-range negative, or partial-range bidirectional current measurement
• This circuit design is tested and includes documentation, data, and layout files.
