What are the key features of TSX3704IPT?
- Ultra-low 5 µA per-comparator supply current extends battery life in energy-harvesting and always-on threshold detection circuits
- Push-pull rail-to-rail output drives logic gates and ADC trigger inputs directly without external pull-up resistors
- Quad 4-channel architecture provides 4 independent comparator functions in a single 14-pin TSSOP, reducing multi-channel BOM
- Wide 1.4V to 16V supply range covers single-cell Li-Ion, 3.3V, 5V, and 12V systems with one part number
What is TSX3704IPT used for?
TSX3704IPT suits battery-powered equipment such as portable instruments, IoT sensors, and smoke detectors where always-on threshold detection must consume minimal current. Its 5 µA per-channel draw and push-pull output make it ideal for window comparators in low-power energy monitors, over-voltage protection circuits, and zero-crossing detectors in 3.3V to 16V systems. The quad package consolidates four threshold detection channels on one TSSOP-14 footprint, saving board space in compact signal conditioning and battery management designs.

Frequently Asked Questions
How low is the supply current of TSX3704IPT, and why does this matter for always-on battery applications?
TSX3704IPT draws only 5 µA per comparator channel, so the full quad device consumes about 20 µA total. In a coin-cell or energy-harvesting design that must monitor 4 voltage thresholds continuously, 20 µA allows a 220 mAh CR2032 coin cell to power the comparator for over 11,000 hours, or roughly 460 days, without any other load.
What output voltage levels does the push-pull output of TSX3704IPT produce, and how does this compare to open-drain comparators?
TSX3704IPT's push-pull output swings close to the supply rails, delivering logic-high near VCC and logic-low near ground without an external pull-up resistor. Open-drain outputs require a pull-up resistor whose value trades off speed against quiescent current; the push-pull configuration eliminates this, reducing the 5 µA active draw by the additional pull-up leakage and simplifying direct connection to 3.3V or 5V CMOS logic inputs.
How does TSX3704IPT's 6 mV maximum input offset voltage affect threshold accuracy in a 3.3V window comparator design?
With a 6 mV maximum input offset voltage referenced to a 3.3V supply, the worst-case threshold error is about 0.18% of full scale. For a window comparator monitoring a 3.0V to 3.6V voltage window in a LiPo battery management circuit, a 6 mV offset shifts the trip point by 6 mV, which is acceptable for cell over-voltage protection but may require reference trimming in precision instrumentation below 1% accuracy targets.
For a 5-channel threshold monitoring board, how would a designer efficiently expand TSX3704IPT beyond its 4 available comparators?
Adding a second TSX3704IPT provides 8 total comparator channels at 40 µA combined supply current, covering up to 5 monitored signals with 3 channels spare. The second TSSOP-14 device adds 14 solder pads on a footprint of about 5 mm × 4 mm, and both devices share the same 1.4V to 16V supply rail and push-pull output logic levels, keeping the design homogeneous with no additional interface circuitry.
