Working Principles

The LM2901DTBR2G is a differential comparator that compares two input voltages and produces a digital output based on the comparison result. It operates by amplifying the voltage difference between the inputs and comparing it to a reference voltage. The output switches to a high or low state depending on whether the voltage at the non-inverting input is higher or lower than the voltage at the inverting input.

Detailed Application Field Plans

The LM2901DTBR2G is commonly used in various industrial and automotive applications, including:

1. Battery management systems
2. Motor control circuits
3. Power supply monitoring
4. Overvoltage/undervoltage protection
5. Signal conditioning circuits
6. Level detection circuits
