Highly accurate current sensor chip that can measure up to 65A and withstand inrush currents up to 13KA.

Programmable Current Sensors


The SC820 is a high-current-capable chip-based current sensor in a wide-body SOP-16 package that realizes a current lead impedance as low as 0.6mΩ on a 10.3mm*10.4mm*2.3mm package, allowing it to be used in power systems that require continuous operation in measuring up to 65A.
