Texas Instruments TLV6710DDCT

Overview

TLV6710DDCT from Texas Instruments is a micropower, 36-V window comparator IC with integrated 400-mV precision reference, dual open-drain outputs rated to 25 V, ±0.75% threshold accuracy over temperature, and 7 µA typical quiescent current - used for overvoltage/undervoltage monitoring in battery-powered systems.

For engineers reviewing the TLV6710DDCT datasheet, TLV6710DDCT pinout, TLV6710DDCT application, or TLV6710DDCT equivalent, this page delivers verified functional behavior, validated pin roles, confirmed window-comparator timing (tpd(HL) = 9.9 µs), thermal specs (RθJA = 201.6 °C/W), and real-world implementation constraints including 1.7-V max input voltage and 25-V pullup capability.

Technical Context

The TLV6710DDCT integrates two independent comparators sharing a trimmed 400-mV internal reference: INA+ monitors falling thresholds (VIT–(INA) = 397–403 mV) with hysteresis (5.5 mV typ), while INB– monitors rising thresholds (VIT+(INB) = 397–403 mV) with 5.2 mV typical hysteresis. Both outputs are open-drain, support 25-V pullup, and assert low on threshold violation.

It operates across 1.8 V to 36 V supply range with undervoltage lockout (UVLO = 1.3–1.7 V) and power-on reset (V(POR) = 0.8 V), enabling robust startup in automotive and industrial rails. Input leakage is ±25 nA max, allowing high-impedance resistor dividers without accuracy degradation.

FAQ

What is the maximum input voltage allowed at INA and INB pins of the TLV6710DDCT?

The TLV6710DDCT specifies an absolute maximum input voltage of +7 V at INA and INB, but the recommended operating range is 0 V to 1.7 V regardless of VDD level. Exceeding 1.7 V risks violating the input common-mode range and degrading threshold accuracy. For higher-voltage monitoring (e.g., 24 V), external resistor dividers must scale the signal into the 0–1.7 V window - the TLV6710DDCT itself does not accept direct high-voltage inputs at these pins.

Can the TLV6710DDCT be used as two independent comparators instead of a window comparator?

Yes, the TLV6710DDCT can operate as two independent comparators: INA+ drives OUTA based on falling thresholds (VIT–(INA)), and INB– drives OUTB based on rising thresholds (VIT+(INB)). Each input has its own hysteresis and reference tie-point. This mode is explicitly supported in the datasheet and enables separate undervoltage and overvoltage monitoring on distinct signals - for example, monitoring battery voltage with INA and system rail voltage with INB, both referenced to the same internal 400-mV source.

What is the purpose of the internal hysteresis in the TLV6710DDCT, and how does it affect design?

The TLV6710DDCT includes 5.5 mV typical hysteresis on INA and 5.2 mV on INB to prevent output oscillation near threshold crossings caused by noise or slow-rising/falling inputs. This hysteresis defines the voltage difference between trip (VIT+) and release (VIT–) points - for example, if VIT+(INB) = 400 mV, then VIT–(INB) ≈ 394.8 mV. Designers must account for this offset when calculating resistor-divider ratios for precise window boundaries, especially in noisy industrial environments where transient rejection is critical.

Does the TLV6710DDCT require an external reference voltage, or is the 400-mV reference fully internal?

The TLV6710DDCT contains a fully internal, factory-trimmed 400-mV reference that requires no external components. This reference is shared by both comparators and is specified with ±0.75% accuracy over –40°C to +125°C. No external reference, capacitors, or calibration circuitry is needed - the 400-mV source is routed internally to the comparator inputs, enabling true single-chip window detection without additional ICs or passive components.

How does the TLV6710DDCT behave during power-up, and what is the startup delay specification?

The TLV6710DDCT incorporates power-on reset (POR) and undervoltage lockout (UVLO) circuitry. When VDD rises above 0.8 V, outputs remain undefined until VDD exceeds 1.8 V and remains stable for ≥155 µs (typical startup delay at 5 V). During this period, OUTA is driven low and OUTB is high-impedance if VDD is between V(POR) and UVLO (1.3–1.7 V). This controlled startup prevents false triggers during rail ramp-up and ensures deterministic output states before system initialization completes - a key requirement for safety-critical monitoring.
