Unique Technique Enable Current Measurement Up To 100A

Deemed a design breakthrough, the company’s latest reference design board measures current up to 100A with an accuracy of ±1% by monitoring voltage drops across a copper track on the PCB. This unique technique uses the AS8510 data-acquisition front end and promises to reduce bill-of-materials cost by eliminating the precision shunt resistor common to current-sensing applications. The AS8510 provides two channels, one of which measures current by sensing the voltage drop over a 10-mm section of a PCB track with a known resistance value and temperature coefficient. The other channel measures the temperature of the copper track. Temperature measurement is via the AS8510 or an external temperature sensor.
