Key Features
- Ultra-low quiescent current below 1 µA enables years of operation on coin-cell batteries
- Push-pull output directly drives CMOS logic without external pull-up resistors, simplifying circuit design
- Wide 1.8V to 5.5V supply range covers both 3.3V and 5V system rails
- Maximum input bias current of 1.5 nA (average) minimizes error from high-impedance resistor divider networks
- 5-pin SOT-23 package with 5000 µV max offset voltage for cost-effective threshold detection
Applications
The TLV3701CDBVTG4 is designed for ultra-low-power threshold detection in battery-operated IoT sensors, wireless nodes, and wearable devices where quiescent current below 1 µA extends coin-cell battery life significantly. It is used in under-voltage lockout circuits, window comparators, and zero-crossing detectors in systems running from 1.8V to 5.5V supplies. Its push-pull output also suits level-shifting applications between 1.8V and 3.3V logic domains without external pull-up resistors.

Frequently Asked Questions
How low is the quiescent current of the TLV3701CDBVTG4, and what battery life benefit does this provide?
The TLV3701CDBVTG4 draws a quiescent current well below 1 µA (typically 380 nA) from its 1.8V to 5.5V supply, allowing a CR2032 coin cell with 200 mAh capacity to power the comparator alone for over 20 years of continuous operation. This nanopower consumption is essential for battery-operated IoT sensors, medical patches, and always-on threshold detectors where sleep-mode current budgets are measured in hundreds of nanoamps.
Why does the push-pull output of the TLV3701CDBVTG4 simplify interfacing compared to open-drain comparators?
The push-pull output of the TLV3701CDBVTG4 actively drives both the high and low output states, eliminating the external pull-up resistor required by open-drain comparators. This reduces the component count by 1 resistor, avoids the RC time constant that a pull-up introduces on rising edges, and provides deterministic 0V to VCC output swing across the full 1.8V to 5.5V supply range, making it directly compatible with CMOS gate inputs.
What is the maximum input offset voltage of the TLV3701CDBVTG4, and how does it affect threshold accuracy?
The TLV3701CDBVTG4 specifies a maximum input offset voltage of 5000 µV (5 mV), which represents the worst-case voltage error at the comparator's switching threshold. For a resistor divider sensing a 3.3V rail, a 5 mV offset translates to approximately 0.15% threshold error, acceptable for battery-voltage monitoring and general threshold detection but important to account for in precision analog circuits requiring tighter than 1% accuracy.
In which under-voltage lockout circuit topology is the TLV3701CDBVTG4 most effective?
The TLV3701CDBVTG4 is most effective in hysteretic UVLO circuits where a resistor divider scales the battery voltage to the comparator's input threshold range of 1.8V to 5.5V, and a small positive-feedback resistor from the push-pull output to the non-inverting input creates a 50 mV to 200 mV hysteresis window. This prevents output chattering near the trip point and safely holds a system in reset when the supply drops below 3V, for example, in Li-Ion battery-powered designs.
