Texas Instruments TLV6700DSER

Overview

TLV6700DSER from Texas Instruments is a micropower, 18-V window comparator IC with integrated 400-mV reference, dual open-drain outputs rated to 18 V, ±0.5% threshold accuracy at 25°C, and 5.5 µA typical quiescent current. It functions as a high-accuracy overvoltage/undervoltage monitor in battery-powered systems requiring rail-independent fault signaling.

For engineers reviewing the TLV6700DSER datasheet, TLV6700DSER pinout, TLV6700DSER application, or TLV6700DSER equivalent, key selection criteria include its 1.8–18 V supply range, adjustable window thresholds via external resistor dividers, built-in 5.5 mV hysteresis, –40°C to 125°C operation, and compatibility with 18-V pull-up rails independent of VDD.

Technical Context

The TLV6700DSER integrates two precision comparators sharing a trimmed 400-mV internal reference: INA+ drives OUTA low on undervoltage (V_IT+ – V_HYS), while INB– drives OUTB low on overvoltage (V_IT+). Both outputs feature open-drain topology with 18-V absolute maximum rating and 40-mA sink capability.

Its architecture supports flexible configuration-as a window comparator using both inputs with opposite polarity, or as two independent monitors-enabled by ultra-low input leakage (<25 nA) and rail-to-rail input voltage range (0–6.5 V) regardless of VDD. Built-in hysteresis rejects noise without external components.

FAQ

What is the function of the TLV6700DSER in a window comparator circuit?

The TLV6700DSER functions as a dual high-accuracy comparator with an internal 400-mV reference to implement window detection: INA+ triggers OUTA low on undervoltage, while INB– triggers OUTB low on overvoltage. Its built-in hysteresis and open-drain outputs allow direct implementation of rail-independent fault monitoring without external components - making TLV6700DSER ideal for compact, low-power supervision designs.

Can TLV6700DSER monitor voltages higher than its VDD supply?

Yes, TLV6700DSER can monitor voltages exceeding VDD - its INA+ and INB– inputs operate from 0 V to 6.5 V regardless of VDD value, enabled by external resistor dividers. For example, with VDD = 5 V, TLV6700DSER can safely supervise a 24-V rail using a 5:1 divider. The device's 18-V output rating further allows pull-up to that same 24-V rail, ensuring TLV6700DSER maintains full functionality across mismatched supply and monitored voltages.

What is the maximum sink current capability of TLV6700DSER outputs?

The TLV6700DSER outputs are rated for 40 mA sink current per channel, verified across the full –40°C to 125°C temperature range and 1.8–18 V supply. This allows direct driving of LEDs, small relays, or microcontroller GPIOs with standard pull-up configurations. At 5 V VDD and 5 mA load, VOL remains ≤250 mV - confirming TLV6700DSER delivers robust low-state performance even under moderate loads.

How does the internal hysteresis of TLV6700DSER improve system reliability?

TLV6700DSER incorporates 5.5 mV typical internal hysteresis between its positive- and negative-going thresholds (V_IT+ – V_IT−), which prevents output oscillation during slow or noisy transitions near the trip point. This eliminates the need for external positive feedback networks, reduces PCB area, and ensures glitch-free operation in electrically harsh environments - a key reliability advantage of TLV6700DSER in automotive and industrial applications.

Is TLV6700DSER suitable for AEC-Q100 qualified automotive applications?

While TLV6700DSER itself is not AEC-Q100 certified, its specified operating junction temperature range of –40°C to 125°C, 18-V absolute maximum ratings, and robust ESD performance (±2500 V HBM) align with automotive subsystem requirements. For AEC-Q100 compliance, TI offers the automotive-grade TLV6700-Q1 variant - TLV6700DSER is appropriate for non-safety-critical automotive modules where qualification is not mandated, such as infotainment power sequencing or cabin sensor supervision.
