Product details
Overview
TLV3701QDBVREP from Texas Instruments is a nanopower rail-to-rail input comparator with 560 nA supply current, −0.1 V to VCC + 5 V input common-mode range, and push-pull CMOS output, designed for battery monitoring and security detection systems operating from −40°C to 125°C.
For engineers reviewing the TLV3701QDBVREP datasheet, TLV3701QDBVREP pinout, TLV3701QDBVREP application, or TLV3701QDBVREP equivalent, key selection criteria include ultra-low quiescent current, reverse-battery protection up to 18 V, extended temperature operation, and SOT-23 (DBV) 5-pin packaging compatibility with space-constrained portable designs.
Technical Context
The TLV3701QDBVREP implements a precision comparator architecture optimized for nanopower operation, featuring input bias current as low as 80 pA (typ) and input offset voltage of 250 µV (typ) at 25°C. Its input stage supports rail-to-rail common-mode operation beyond the supply rails by up to 5 V, enabling high-side sensing without level-shifting circuitry.
It delivers push-pull CMOS output with VOH ≥ VCC − 0.08 V and VOL ≤ 80 mV at 50 µA load, eliminating external pull-up resistors. Propagation delay is 36 µs (typ) at 50 mV overdrive with 2.7 V supply, and PSRR exceeds 80 dB across 5–15 V supply range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3701QDR | Same core specs but SOIC-8 (D) package; higher thermal resistance (θJA = 157°C/W vs 324°C/W) | Preferred where manual assembly, test probing, or higher power dissipation margin is needed | Select TLV3701QDR only when SOT-23 layout constraints prevent use of TLV3701QDBVREP |
| TLV7011DBVR | Lower supply current (320 nA), but narrower supply range (1.4–5.5 V); no reverse-battery protection | Better suited for single-cell LiPo or USB-powered devices below 5.5 V; not viable for 12 V industrial rails | Choose TLV7011DBVR only for sub-5.5 V battery systems prioritizing lowest possible IQ over voltage flexibility |
Compared with TLV3701QDBVREP, TLV3701QDR offers identical electrical performance in larger SOIC-8 packaging for easier prototyping, while TLV7011DBVR reduces IQ further but sacrifices supply voltage range and reverse-battery robustness - making TLV3701QDBVREP the optimal choice for wide-input, harsh-environment, space-constrained deployments.

FAQ
What is the maximum input voltage tolerance for TLV3701QDBVREP relative to VCC?
The TLV3701QDBVREP supports an input common-mode voltage range from −0.1 V to VCC + 5 V. This means either input (IN+ or IN−) can safely operate up to 5 V above the positive supply rail without damage or phase reversal. Absolute maximum differential input voltage is ±20 V, and absolute maximum supply voltage is 17 V. These ratings enable direct high-side sensing in TLV3701QDBVREP-based designs without external clamping circuitry.
Does TLV3701QDBVREP require an external pull-up resistor on its output?
No, TLV3701QDBVREP does not require an external pull-up resistor. It features a push-pull CMOS output stage capable of sourcing and sinking up to ±10 mA. At 2.7 V supply, VOH is typically VCC − 0.08 V and VOL is ≤80 mV at 50 µA load. This eliminates the need for external components, reduces PCB area, and improves noise immunity compared to open-drain comparators - a key advantage confirmed in the TLV3701QDBVREP datasheet Figure 3–7.
What is the guaranteed input offset voltage specification for TLV3701QDBVREP over temperature?
The TLV3701QDBVREP has a maximum input offset voltage of 5000 µV at 25°C and 7000 µV across the full −40°C to 125°C operating range. The typical value is 250 µV at 25°C, with an offset drift of 3 µV/°C. These values are specified in the "electrical characteristics" table of the TLV3701QDBVREP datasheet (SGLS170) and apply to the Q-suffix automotive-grade variant, ensuring predictable threshold accuracy in TLV3701QDBVREP-based battery monitoring circuits.
Can TLV3701QDBVREP operate from a 1.8 V supply?
No, TLV3701QDBVREP cannot operate from a 1.8 V supply. Its minimum recommended supply voltage is 2.7 V across the full −40°C to 125°C temperature range. Operation below 2.7 V is outside the specified operating conditions and may result in undefined behavior, increased propagation delay, or failure to meet input/output voltage specifications. For 1.8 V systems, consider TI's TLV7011DBVR (1.4–5.5 V range), though it lacks reverse-battery protection and extended common-mode capability of TLV3701QDBVREP.
What packaging and reel configuration is used for TLV3701QDBVREP?
TLV3701QDBVREP is supplied in the SOT-23 (DBV) 5-pin plastic package, with dimensions 2.9 mm × 1.6 mm × 1.15 mm. It ships in tape-and-reel format with 3000 units per reel, reel diameter 180.0 mm, reel width 8.4 mm, and pin 1 located in quadrant Q3 per TI's tape orientation standard. The device carries RoHS-compliant NIPDAU lead finish and is rated MSL Level-1 (unlimited floor life at ≤30°C/60% RH), as documented in TI's PACKAGE OPTION ADDENDUM for TLV3701QDBVREP.
