SC212KSIT
120 kHz Bandwidth, High Voltage Isolation Current Sensor with Integrated Overcurrent Detection
General Description
The SEC™ SC212KSIT current sensor provides economical and precise means for current sensing applications in industrial, commercial, and communications systems.
The device is offered in a small footprint surface mount package that allows easy implementation in customer applications.
The SC212KSIT consists of a precision linear Hall sensor integrated circuit with a copper conduction path located near the surface of the silicon die.
Applied current flows through the copper conduction path, and the analog output voltage from the Hall sensor linearly tracks the magnetic field generated by the applied current.
The accuracy of the SC212KSIT is maximized with this patented packaging configuration because the Hall element is situated in extremely close proximity to the current to b...
