Product details
Overview
TLV7032QDDFRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 automotive-compliant comparator with push-pull outputs, 315 nA quiescent current, 3 µs propagation delay, 6.5 mV internal hysteresis, and rail-to-rail input operation from 1.6 V to 6.5 V supply. It serves as a precision voltage monitor in infotainment power sequencing and battery fault detection circuits.
For engineers reviewing the TLV7032QDDFRQ1 datasheet, TLV7032QDDFRQ1 pinout, TLV7032QDDFRQ1 application, or TLV7032QDDFRQ1 equivalent, this page delivers verified specifications, validated dual-channel pin mapping for VSSOP-8, confirmed automotive-grade thermal and ESD performance, and real-world functional alternatives for voltage monitoring in harsh-temperature environments.
Technical Context
The TLV7032QDDFRQ1 implements a dual independent comparator core with internal power-on-reset (POR) that forces both outputs low during supply ramp-up until VCC ≥ 1.6 V for ≥200 µs. Each channel features rail-to-rail inputs extending 100 mV beyond VCC and includes fixed 6.5 mV hysteresis to prevent chatter on slow-moving signals.
Its push-pull output stage sources/sinks up to 3 mA at 5 V while maintaining VOL ≤ 350 mV and VOH ≥ 4.65 V. The device operates across –40°C to +125°C ambient, meets AEC-Q100 HBM ±2 kV and CDM ±1 kV ESD requirements, and supports single-supply configurations with VEE tied to ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 6.5 V - compatible with 1.8 V, 3.3 V, and 5 V automotive microcontroller I/O domains |
| Quiescent Current / Channel | 315 nA - enables always-on battery monitoring without measurable drain on 12 V systems |
| Propagation Delay | 3 µs - fast enough to detect overvoltage faults before downstream protection triggers |
| Input Offset Voltage | ±0.1 mV (min), ±8 mV (max) - ensures accurate threshold detection across temperature |
| Hysteresis | 6.5 mV (typ) - suppresses noise-induced toggling on noisy sensor or bus voltage rails |
| Common-Mode Input Range | VEE to VCC + 0.1 V - accepts inputs up to 100 mV above supply rail for robust signal margin |
| Output Type | Push-pull - eliminates need for external pull-up resistors in digital interface applications |
Pinout & Package
VSSOP-8 package (3.00 mm × 3.00 mm body size), thermally optimized for automotive PCB layouts with RθJA = 211.7°C/W.

Applications
| Power Sequencing Monitor | Battery Voltage Supervisor |
|---|---|
Use Scenario: Monitoring multiple DC-DC converter enable signals and reset lines in an automotive head unit to ensure correct power-up order. IC Role / Device Role / Timing Role: Dual comparator independently validates VDD1 ≥ 3.3 V and VDD2 ≥ 5.0 V before releasing processor reset. Use Value: Prevents firmware lockup due to out-of-spec power sequencing; eliminates need for discrete voltage detectors per rail. | Use Scenario: Detecting undervoltage (<11.5 V) and overvoltage (>15.5 V) conditions on a 12 V vehicle battery during engine start-stop cycles. IC Role / Device Role / Timing Role: One channel compares battery voltage against low-threshold reference; second channel compares against high-threshold reference. Use Value: Enables early warning of alternator failure or parasitic drain; 315 nA current draw extends backup battery life in telematics eCall modules. |
| Infotainment System Wake-Up | Audio Amplifier Protection |
Use Scenario: Waking a low-power MCU from sleep mode when USB-C port detects VBUS presence or headset insertion. IC Role / Device Role / Timing Role: Comparator monitors USB VBUS (5 V) or audio jack tip/ring voltage to generate wake interrupt. Use Value: Achieves sub-µA system standby with deterministic 3 µs response - faster than typical GPIO-based wake schemes. | Use Scenario: Protecting Class-D amplifier ICs from thermal shutdown by monitoring heatsink temperature via NTC thermistor voltage divider. IC Role / Device Role / Timing Role: Compares thermistor output against two thresholds to trigger mute (warning) and shutdown (critical) signals. Use Value: Dual-channel architecture replaces two discrete comparators; internal hysteresis prevents oscillation near trip points in noisy amplifier environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7032DR | Commercial-grade (–40°C to +125°C), same electrical specs but not AEC-Q100 qualified | Lacks automotive qualification documentation and FIT report; unsuitable for safety-critical ECUs | Select TLV7032DR only for non-automotive industrial or consumer designs requiring identical performance at lower cost |
| LMV7235QMA/NOPB | Higher ICC (1.1 µA), slower tPD (120 ns), open-drain output, no internal hysteresis | Requires external hysteresis resistors and pull-up; less suitable for noisy battery monitoring | Choose LMV7235QMA/NOPB when open-drain flexibility is required and higher power budget allows |
Compared with TLV7032DR and LMV7235QMA/NOPB, the TLV7032QDDFRQ1 uniquely combines AEC-Q100 qualification, nanopower consumption, push-pull drive, and factory-trimmed hysteresis - making it the only option for space-constrained, always-on automotive voltage supervisors needing zero external components.

FAQ
What is the operating temperature range for TLV7032QDDFRQ1?
The TLV7032QDDFRQ1 is qualified for automotive Grade 1 operation, with a guaranteed ambient operating temperature range of –40°C to +125°C. This specification is validated per AEC-Q100 standards and applies across all electrical parameters in the datasheet, including propagation delay, input offset voltage, and supply current. The TLV7032QDDFRQ1 maintains full functionality within this range without derating.
Does TLV7032QDDFRQ1 require external hysteresis resistors?
No, the TLV7032QDDFRQ1 includes factory-trimmed internal hysteresis of 6.5 mV (typical), eliminating the need for external hysteresis resistors. This fixed hysteresis is integrated into the comparator core and functions across the full –40°C to +125°C temperature range and 1.6 V to 6.5 V supply range. The TLV7032QDDFRQ1 is designed for immediate use in noisy environments such as battery monitoring without additional passive components.
Can TLV7032QDDFRQ1 operate from a single 3.3 V supply?
Yes, the TLV7032QDDFRQ1 operates from a single 3.3 V supply with VEE connected to ground. Its rail-to-rail input stage accepts common-mode voltages from 0 V to 3.4 V, and its push-pull output swings from near ground to within 350 mV of VCC. At 3.3 V, the TLV7032QDDFRQ1 draws 315 nA per channel and delivers 3 µs propagation delay - making it ideal for low-voltage automotive microcontroller interfaces.
What is the purpose of the Power-On Reset (POR) circuit in TLV7032QDDFRQ1?
The POR circuit in TLV7032QDDFRQ1 holds both outputs low until VCC exceeds 1.6 V and remains stable for at least 200 µs. This ensures deterministic startup behavior during cold cranking or low-battery conditions, preventing spurious logic transitions that could corrupt MCU state or trigger false alarms. The TLV7032QDDFRQ1's POR is fully integrated and requires no external components - a key differentiator from comparators lacking built-in reset control.
Is TLV7032QDDFRQ1 pin-compatible with other devices in the TLV703x-Q1 family?
Yes, the TLV7032QDDFRQ1 in VSSOP-8 (DDF) package shares identical pinout with TLV7042QDDFRQ1 (open-drain version) and TLV7032DR (commercial version). All three use the same 8-pin mapping: OUTA, INA–, INA+, VEE, INB+, INB–, OUTB, VCC. However, TLV7032QDDFRQ1 is not pin-compatible with SOT-23-8 variants due to different pad layout and thermal pad configuration - board redesign is required when switching between VSSOP and SOT-23 packages.
