Functional Description and Application Information
4.20
The Current Sense Module is implemented to amplify the voltage drop across an external shunt resistor to measure the actual
application current using the internal Analog Digital Converter Channel 9. Typical application is the motor current in a window lift
control module
The implementation is based on a switched capacitor solution to eliminate unwanted offset.To fit several application scenarios,
eight different GAIN setting are implemented.
