What are the key features of LM339APWRE4?
- 4 independent open-collector comparator channels in a single 14-pin TSSOP package reduce BOM count in multi-threshold detection circuits
- Wide supply range of ±15 V (30 V single-supply) supports industrial and automotive signal levels without additional level translation
- 4 mV maximum input offset voltage and 0.25 µA bias current at 25°C deliver reliable threshold detection for precision window comparator designs
What is LM339APWRE4 used for?
The LM339APWRE4 is widely used in over-voltage and under-voltage detection circuits, battery management systems, and analog window comparators for industrial process control. Its open-collector outputs allow multiple comparators to share a single pull-up resistor for wired-AND logic in fault detection networks. Motor drive and power supply feedback applications also rely on its wide supply range and reliable 4-channel integration.

Frequently Asked Questions
Why does the LM339APWRE4 use open-collector outputs, and how do these interface with 3.3 V logic systems?
Open-collector outputs on the LM339APWRE4 require an external pull-up resistor to define the logic high level, which means the same comparator can pull its output to 3.3 V, 5 V, or any rail up to 30 V simply by choosing the pull-up supply. This allows the LM339APWRE4 operating from a 12 V automotive supply to drive directly into a 3.3 V MCU GPIO by pulling up through the 3.3 V rail, eliminating any level-shift IC.
For a 4-channel window comparator circuit, what is the minimum detectable voltage difference using the LM339APWRE4?
The LM339APWRE4 specifies a maximum input offset voltage of 4 mV and a bias current of 0.25 µA at 25°C. For a window comparator with 10 kΩ reference resistors, bias current contributes 2.5 mV of additional offset, giving a worst-case total of 6.5 mV. Designers targeting thresholds narrower than 10 mV should use matched low-value resistors or a precision comparator with lower offset, while the LM339APWRE4 handles most industrial thresholds above 20 mV reliably.
How does packaging 4 comparator channels in the LM339APWRE4 reduce cost versus using discrete single comparators?
Integrating 4 comparators in one 14-pin TSSOP (R-PDSO-G14) package typically costs 30–50% less than purchasing 4 individual single-comparator ICs, while also reducing board area from 4 separate footprints to a single 5 mm × 4.4 mm TSSOP outline. Shared supply decoupling capacitors and fewer assembly placements further reduce BOM cost and manufacturing time in high-volume production of power monitors and fault detection boards.
