Product details
Overview
TLV3701IDBVRG4 from Texas Instruments is a nanopower, single-channel comparator with push-pull CMOS output, designed for ultra-low-quiescent-current sensing in battery-powered systems. It draws only 560 nA supply current per channel, operates from 2.7 V to 16 V, supports input common-mode range from –0.1 V to VCC + 5 V, and features reverse battery protection up to 20 V. It is used in portable battery monitoring and handheld medical instruments where supply current and rail-overdrive capability are critical.
For engineers reviewing the TLV3701IDBVRG4 datasheet, TLV3701IDBVRG4 pinout, TLV3701IDBVRG4 application, or TLV3701IDBVRG4 equivalent, this page delivers verified technical context, exact pin functions for the SOT-23-5 package, real-world application mappings, and two validated alternative comparators with documented functional and parametric differences.
Technical Context
The TLV3701IDBVRG4 implements a precision nanopower comparator core with internal power-on-reset (POR) that holds the output low for up to 3 ms during supply ramp-up. Its input stage supports fail-safe operation - inputs remain high-impedance and undamaged even when biased up to 5 V above VCC or while VCC is unpowered.
It uses a push-pull CMOS output stage eliminating external pull-up resistors, enabling rail-to-rail output swing (VOH = VCC – 80 mV, VOL = 8 mV at 2 μA) and fast switching (tPLH/tPHL = 16–45 μs at 50 mV overdrive). Input offset voltage is 250 μV typical, with hysteresis of 1–5 mV and CMRR up to 88 dB across full supply range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3701CDBVR | Commercial-grade (0°C to 70°C); identical electrical specs and SOT-23-5 package | Not rated for extended temperature environments; unsuitable for industrial or automotive deployments | Select TLV3701CDBVR only for cost-sensitive consumer products operating within 0–70°C ambient |
| TLV7011DBVR | Lower supply current (350 nA), wider supply range (1.4 V to 16 V), but reduced input voltage range (to VCC + 0.2 V) | Lacks over-rail input capability; cannot replace TLV3701IDBVRG4 in high-side sensing or reverse-battery scenarios | Choose TLV7011DBVR when ultra-low IQ dominates design priority and input stays within rails |
Compared with TLV3701CDBVR, TLV3701IDBVRG4 adds –40°C to +125°C qualification and reverse-battery robustness; compared with TLV7011DBVR, it trades 210 nA higher IQ for 4.8 V additional input headroom and fail-safe operation - making it uniquely suited for harsh, battery-critical systems.

FAQ
What is the maximum input voltage allowed on TLV3701IDBVRG4 pins?
The TLV3701IDBVRG4 supports input voltages from –0.1 V to VCC + 5 V, with absolute maximum rating of ±20 V differential and 16 V above GND. This over-rail capability enables direct high-side sensing without level-shifting circuitry, and its fail-safe inputs remain undamaged even when VCC is unpowered - a key advantage in battery systems with loose sequencing control.
Does TLV3701IDBVRG4 require an external pull-up resistor on its output?
No. TLV3701IDBVRG4 features a push-pull CMOS output stage that actively drives both high and low states. Unlike open-drain comparators, it does not require an external pull-up resistor - reducing component count, saving board space, and eliminating standby current through the pull-up. Output voltage swings to within 80 mV of VCC (high) and 8 mV above GND (low) at 2 μA load.
What is the purpose of the Power-On Reset (POR) function in TLV3701IDBVRG4?
The TLV3701IDBVRG4 integrates an internal POR circuit that holds the output low for up to 3 ms after VCC crosses 1.5 V during power-up or brownout recovery. This ensures a known, glitch-free initial state without requiring external reset ICs or RC networks - simplifying design and improving reliability in battery-powered systems where supply ramp rates vary.
Can TLV3701IDBVRG4 operate from a 1.8 V supply?
No. TLV3701IDBVRG4 has a minimum recommended supply voltage of 2.7 V over the industrial temperature range (–40°C to +125°C). At 1.8 V, the device is outside its specified operating conditions and may exhibit undefined behavior, including failure to assert correct output logic or increased propagation delay. For sub-2 V operation, consider TI's TLV7011 (1.4 V min) - though it lacks over-rail input capability.
How does TLV3701IDBVRG4 handle reverse battery connection?
TLV3701IDBVRG4 includes reverse battery protection up to –20 V on the VCC pin relative to GND. Its internal architecture prevents destructive current flow during incorrect battery installation, protecting both the comparator and downstream circuitry. This feature is validated across the full –40°C to +125°C range and eliminates the need for external series diodes or MOSFET-based protection in portable equipment.
