Lateral Sensitive Programmable Hall-Effect Current Sensor IC S4-CSA01 with a Supply Voltage Range from 4.5V to 5.5V
The S4-CSA01 Lateral sensitive Programmable Hall-Effect Current sensor IC is a Hall-effect based Current Sensor employing proprietary vertical backside Hall sensor technology. It is assembled in a small SOIC-8 package and can be mounted on top of a primary current bar or conductor on PCB.
The IC contains a fast analog signal path with factory calibrated gain and offset temperature drift compensation. Various parameters such as sensitivity, zero output voltage, temperature drift, and signal bandwidth as well as operating modes such as ratiometric versus fixed, and differential versus additive can be programmed in the application.
