Applications
The LMV339MT NOPB is used in battery management systems, portable instruments, and IoT sensor nodes where four comparator channels are needed from a single compact package. Its 2.7 V minimum supply makes it compatible with single-cell lithium and two-cell alkaline battery rails commonly found in wearable and industrial handheld devices. Open-drain outputs allow flexible interfacing with 3.3 V and 5 V microcontrollers without additional level-shifting components.

Frequently Asked Questions
Can the LMV339MT NOPB operate from a 3.3 V single supply, and what input voltage range is valid at that supply level?
Yes, the LMV339MT NOPB operates from a supply as low as 2.7 V, so a 3.3 V rail is fully within specification. At 3.3 V supply, the common-mode input voltage range spans from ground to approximately 3.3 V, enabling detection of signals across the full rail without clipping or output errors.
When would a designer choose the LMV339 quad package over two dual-comparator devices for a 4-channel detection circuit?
Using a single 14-pin TSSOP LMV339 instead of two separate dual-comparator packages reduces board area by roughly 30%, cuts BOM line items by one, and simplifies power routing since all 4 channels share one supply decoupling network. This trade-off favors the quad part in compact PCBs with limited routing space.
How does the open-drain output of the LMV339MT NOPB enable multiple comparators to share a single interrupt line to a microcontroller?
Open-drain outputs allow any of the 4 comparator channels to pull a shared output node low simultaneously, creating a wired-OR interrupt signal. A single external pull-up resistor of 10 kohm to the microcontroller's 3.3 V I/O rail is sufficient, and the MCU then reads individual comparator outputs to determine which of the 4 channels triggered the event.
