What is LM2901DRSV used for?
The LM2901DRSV is widely used in window comparator circuits, overvoltage and undervoltage detection, and threshold trigger circuits in industrial and consumer electronics. Its 4 independent channels make it efficient for monitoring multiple analog voltage rails or sensor outputs simultaneously within a single SOIC package. Battery management systems, motor control boards, and general-purpose analog signal conditioning circuits also deploy it for cost-effective voltage level detection.

Frequently Asked Questions
What supply voltage range does LM2901DRSV support for mixed single-supply and dual-supply system designs?
The LM2901DRSV operates from a single supply voltage of 2 V to 36 V, or from dual supply rails of plus or minus 1 V to plus or minus 18 V. This wide range allows the same device to work in 3.3 V logic systems, 5 V automotive circuits, and 24 V industrial control panels, making it a versatile comparator for mixed-voltage system designs.
How does the open-collector output of LM2901DRSV enable wired-OR logic implementations?
The LM2901DRSV's open-collector outputs allow multiple comparator outputs to be connected to a single pull-up resistor, forming a wired-OR configuration where any comparator asserting low drives the shared output low. This enables interrupt aggregation from 4 independent threshold detectors without requiring additional logic gates, saving space and cost in alarm systems and fault detection circuits operating at voltages up to 36 V.
For a window comparator detecting voltages between 2.5 V and 3.0 V, how many LM2901DRSV channels does the design need?
A window comparator requires 2 comparator channels: one comparing the input against the 3.0 V upper threshold and one against the 2.5 V lower threshold. The LM2901DRSV contains 4 independent comparators in a single SOIC package, so a single device can implement 2 complete window comparators simultaneously, making it ideal for dual-rail voltage monitoring applications in power management boards.
