Texas Instruments TLV3701IDBVR

Overview

TLV3701IDBVR 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 V_CC + 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 TLV3701IDBVR datasheet, TLV3701IDBVR pinout, TLV3701IDBVR application, or TLV3701IDBVR equivalent, key selection criteria include its 560 nA supply current, –40°C to 125°C industrial temperature grade, 5-pin SOT-23 package, push-pull output eliminating external pull-up resistors, and over-rail input tolerance enabling direct high-voltage signal monitoring without level-shifting.

Technical Context

The TLV3701IDBVR implements a precision nanopower comparator core with internal power-on-reset (POR) that holds 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 unpowered or biased up to 16 V independent of V_CC.

It uses a push-pull CMOS output stage delivering rail-to-rail sourcing/sinking capability (±50 µA), with propagation delays as low as 16 µs at 50 mV overdrive and rise/fall times under 0.2 µs into 10 pF. Input offset voltage is 250 µV (typ), with hysteresis of 1–5 mV and CMRR up to 88 dB across full supply range.

FAQ

What is the maximum input voltage allowed on TLV3701IDBVR pins when V_CC = 3.3 V?

The TLV3701IDBVR allows input voltages from –0.1 V to V_CC + 5 V, so with 3.3 V supply, inputs may safely reach up to 8.3 V. Absolute maximum rating is 20 V differential or 16 V absolute - whichever is smaller - ensuring compatibility with 9 V batteries and industrial sensor outputs without external clamping.

Does TLV3701IDBVR require an external pull-up resistor on its output?

No. TLV3701IDBVR features a push-pull CMOS output stage capable of actively driving high and low states. Unlike open-drain comparators, it does not require an external pull-up resistor - simplifying layout, reducing power loss, and eliminating a potential source of leakage in battery-critical designs.

Can TLV3701IDBVR operate with V_CC disconnected while inputs remain active?

Yes. TLV3701IDBVR inputs are fail-safe: they remain high-impedance and undamaged when V_CC is unpowered or below minimum, and accept voltages from –0.1 V to 16 V. This enables safe signal routing in systems with asynchronous power domains or hot-swap interfaces without risk of latch-up or damage.

What is the typical propagation delay of TLV3701IDBVR at 100 mV overdrive and 5 V supply?

At 100 mV input overdrive and V_CC = 5 V, TLV3701IDBVR exhibits typical propagation delays of 34 µs (low-to-high) and 45 µs (high-to-low). These values scale inversely with overdrive - e.g., at 50 mV overdrive, delays reduce to 16 µs - making it well-suited for slowly varying DC thresholds rather than high-frequency signal discrimination.

How does the power-on-reset (POR) function behave in TLV3701IDBVR?

TLV3701IDBVR incorporates an internal POR circuit that activates when V_CC crosses 1.5 V during power-up or power-down. During this period - lasting up to 3 ms - the output is held low regardless of input state. This guarantees a defined initial condition for downstream logic and eliminates spurious wake-ups in battery-powered systems.
