Texas Instruments TLV3701CDBVT

Overview

TLV3701CDBVT from Texas Instruments is a nanopower, single-channel comparator with push-pull CMOS output, 560 nA supply current per channel, input common-mode range from –0.1 V to V_CC + 5 V, and operation across 2.5 V to 16 V supply. It is designed for ultra-low-power battery monitoring in portable medical devices and handheld instruments.

For engineers reviewing the TLV3701CDBVT datasheet, TLV3701CDBVT pinout, TLV3701CDBVT application, or TLV3701CDBVT equivalent, key selection criteria include quiescent current budget, rail-exceeding input tolerance, push-pull output drive capability without external pull-up, reverse-battery protection up to 20 V, and SOT-23-5 packaging for space-constrained designs.

Technical Context

The TLV3701CDBVT implements a precision nanopower comparator core with internal power-on-reset (POR) that holds output low for ≤3 ms during V_CC ramp-up. Its input stage supports fail-safe operation up to 16 V independent of supply voltage, enabling robust interfacing with unpowered or undervolted signal sources.

It features over-the-rail input capability (–0.1 V to V_CC + 5 V), reverse-battery protection, and push-pull output capable of sourcing/sinking ≥50 µA while maintaining VOL ≤ 80 mV and VOH ≥ V_CC – 450 mV across temperature. Propagation delay is 16 µs (typ.) at 50 mV overdrive with 10 pF load.

FAQ

What is the maximum input voltage allowed on TLV3701CDBVT pins?

The TLV3701CDBVT supports an input common-mode voltage range from –0.1 V to V_CC + 5 V, with absolute maximum ratings permitting up to ±20 V differential input and 16 V above GND on either input-enabling safe operation even when V_CC is unpowered. This makes TLV3701CDBVT ideal for battery voltage monitoring where input may exceed supply.

Does TLV3701CDBVT require an external pull-up resistor on its output?

No. TLV3701CDBVT features a push-pull CMOS output stage capable of actively driving both high and low states, eliminating the need for an external pull-up resistor. This reduces component count, board area, and standby power-critical advantages in TLV3701CDBVT-based portable designs.

What is the typical propagation delay of TLV3701CDBVT at 5 V supply?

At V_CC = 5 V, 10 pF load, and 50 mV input overdrive, TLV3701CDBVT exhibits a typical propagation delay of 16 µs for both high-to-low and low-to-high transitions. Delay increases to ~45 µs at 10 mV overdrive, making TLV3701CDBVT well-suited for sub-10 kHz event detection in low-power systems.

Can TLV3701CDBVT operate from a 2.5 V supply?

Yes. TLV3701CDBVT is fully specified from 2.5 V to 16 V supply, including all key parameters (ICC, VIO, propagation delay) across this range. At 2.5 V, supply current remains near 560 nA, and input common-mode range extends to –0.1 V to 7.5 V-confirming TLV3701CDBVT's suitability for single-cell Li-ion and 2xAA applications.

Is TLV3701CDBVT pin-compatible with other packages in the TLV370x family?

No. TLV3701CDBVT uses the 5-pin SOT-23 (DBV) package with unique pinout (OUT, GND, IN+, IN−, V_CC). The 8-pin SOIC (D) and PDIP (P) variants have different pin counts and arrangements-including NC pins-and are not mechanically or electrically interchangeable with TLV3701CDBVT without PCB redesign.
