Key Features
- Rail-to-rail input common-mode voltage range from ground to VCC enables accurate comparison at supply extremes in low-voltage 1.8 V to 5.5 V systems
- Push-pull output eliminates the need for external pull-up resistors, simplifying PCB layout and reducing BOM component count
- Ultra-compact 4-pin DSBGA package (roughly 0.64 mm x 0.64 mm) enables space-critical placements in wearables and IoT sensor nodes
- Single-supply operation down to 1.8 V makes TLV4041R1 ideal for battery-powered and energy-harvesting applications
Applications
TLV4041R1 is suited for threshold detection and level-shifting in battery-powered wearables, IoT sensor nodes, and portable medical devices where board space and supply voltage are tightly constrained. Its rail-to-rail input range allows accurate voltage comparisons near the supply rails, making it useful in low-battery detection circuits and window comparator configurations powered from 1.8 V to 5.5 V. The push-pull output directly drives logic inputs or LEDs without external resistors, streamlining designs in hearing aids, fitness trackers, and compact industrial sensors.

Frequently Asked Questions
What supply voltage range does TLV4041R1 support and how does that fit coin-cell battery designs?
TLV4041R1 operates from a single supply of 1.8 V to 5.5 V, covering the discharge curve of CR2032 coin cells (2 V to 3.3 V) without a boost regulator. Its rail-to-rail input allows valid comparisons even when VCC drops below 2.5 V near end-of-battery life. This makes it reliable for low-battery alert circuits, door sensors, and other coin-cell-powered devices requiring accurate threshold detection.
How does the push-pull output of TLV4041R1 differ from open-drain comparators in a 3.3 V logic system?
Unlike open-drain comparators that require an external pull-up resistor to set output high, TLV4041R1's push-pull output actively drives both logic high and logic low states. In a 3.3 V system this eliminates a 10 kΩ to 100 kΩ pull-up resistor, saving board space and slightly reducing power consumption. Push-pull outputs also switch faster, reducing propagation delay in time-critical threshold crossing detection.
For a wearable PCB with 0.5 mm pitch components, what board area does TLV4041R1 in DSBGA occupy?
TLV4041R1 is housed in a 4-pin DSBGA package with a footprint of approximately 0.64 mm x 0.64 mm. This is among the smallest comparator packages available, occupying under 0.5 mm² of board area. The tiny size suits dense wearable and hearable PCBs where every square millimeter is competed for, allowing placement close to sensors without impacting overall device dimensions.
When is TLV4041R1 preferred over a dual comparator like LMV393 in a single-channel detection circuit?
TLV4041R1 is preferred when only one comparator channel is needed and board space is the binding constraint, because its 4-pin DSBGA footprint is roughly 4x smaller than the 8-pin SOT-23 package of LMV393. Eliminating an unused second comparator also simplifies routing. For 1.8 V to 5.5 V single-supply designs with push-pull output requirements, TLV4041R1 avoids the 5 V minimum supply limitation of some older dual-comparator devices.
