Product details
Overview
TLV9032QDRQ1 from Texas Instruments is an AEC-Q100 Grade 1 dual-channel automotive precision comparator with push-pull output, 300 µV input offset voltage, 100 ns propagation delay, and 16 µA per channel quiescent current across 1.65 V to 5.5 V supply. It operates from –40°C to +125°C ambient and features fault-tolerant inputs (–0.3 V to 6 V), Power-On Reset (POR), and rail-to-rail input range exceeding supply rails - used in HEV/EV powertrain voltage monitoring and body control module window lift detection.
For engineers reviewing the TLV9032QDRQ1 datasheet, TLV9032QDRQ1 pinout, TLV9032QDRQ1 application, or TLV9032QDRQ1 equivalent, key selection considerations include its push-pull output drive capability (±100 mA short-circuit current), guaranteed startup behavior via POR, low-input-bias-current (5 pA) design for high-impedance sensing, and AEC-Q100 qualification for automotive safety-critical subsystems.
Technical Context
The TLV9032QDRQ1 implements a dual-comparator architecture with independent input stages featuring ESD-hardened, fault-tolerant inputs capable of withstanding up to 6 V regardless of supply voltage. Its internal POR circuit ensures output remains in a known state until VS ≥ 1.65 V, eliminating transients during power ramp-up/down.
Each comparator delivers 100 ns propagation delay at 5 V with only 16 µA per channel quiescent current, achieving a speed-to-power ratio optimized for always-on automotive subsystems. The push-pull output stage supports direct LED driving and MOSFET gate control without external pull-ups, while maintaining 75 mV VOL (at 4 mA sink) and 75 mV VOH (at 4 mA source) over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct operation from 1.8 V, 3.3 V, or 5 V automotive rails without level-shifting |
| Input Offset Voltage | ±0.3 mV (typ) - supports precise threshold detection in battery voltage supervision and motor phase monitoring |
| Propagation Delay | 100 ns (high-to-low, 5 V) - meets timing requirements for fast-response overvoltage/undervoltage protection |
| Quiescent Current | 16 µA per channel - allows integration into low-power wake-up circuits and always-on domain sensors |
| Input Common-Mode Range | (V−) − 0.2 V to (V+) + 0.2 V - permits monitoring signals beyond supply rails, e.g., CAN bus bias or sensor outputs |
| Output Drive Capability | ±100 mA short-circuit current - directly drives LEDs, relays, or logic inputs without external buffers |
| ESD Rating | HBM ±2 kV, CDM ±1 kV - satisfies AEC-Q100 stress requirements for under-hood and cabin environments |
Pinout & Package
TLV9032QDRQ1 is packaged in an 8-pin SOIC (D) with nominal body size 3.91 mm × 4.90 mm, lead pitch 1.27 mm, and exposed thermal pad connected to V−. Pinout follows standard "South East" configuration for dual comparators.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 | Comparator 1 output | Push-pull active-high/active-low output; sinks/source up to 100 mA; no external pull-up required |
| IN1− | Inverting input of Comp1 | Fault-tolerant to −0.3 V to 6 V; supports overvoltage-safe sensing in noisy automotive domains |
| IN1+ | Non-inverting input of Comp1 | Rail-to-rail input stage enables direct connection to resistive divider outputs or sensor references |
| V− | Negative supply / GND reference | Reference node for all inputs and outputs; thermal pad must be soldered directly to this pin |
| IN2+ | Non-inverting input of Comp2 | Independent channel for redundant sensing or multi-threshold detection (e.g., window comparator) |
| IN2− | Inverting input of Comp2 | Matches IN1− specs; enables differential or complementary signal comparison |
| OUT2 | Comparator 2 output | Functionally identical to OUT1; supports dual independent decision paths in single package |
| V+ | Positive supply | Accepts 1.65–5.5 V; PSRR ≥ 75 dB ensures stable operation amid supply ripple from DC/DC converters |
Key Features
| Feature | Design Value |
|---|---|
| Power-On Reset (POR) | Guarantees defined output state until VS ≥ 1.65 V - prevents spurious actuation during cold cranking or battery recovery |
| Fault-Tolerant Inputs | Withstand −0.3 V to 6 V independent of V+ - eliminates need for external clamping diodes in 12 V/24 V systems |
| Precision Input Offset | ±0.3 mV typical (±2 mV max over temp) - enables accurate battery cell balancing and low-voltage LDO monitoring |
| Low Quiescent Current | 16 µA per channel at 25°C - extends runtime in always-on vehicle modules such as door lock controllers |
| Push-Pull Output | No external pull-up needed; drives capacitive loads (e.g., MOSFET gates) and LEDs directly - reduces BOM count and PCB area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual automotive comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9022QDRQ1 | Open-drain output; requires external pull-up; identical offset, speed, and supply specs | Suitable where wired-OR logic, level translation, or higher voltage output swing (>V+) is needed | Select TLV9022QDRQ1 when interfacing with legacy 12 V logic or implementing shared interrupt lines |
| LM7322QDRQ1 | Higher IQ (1.3 mA/ch), wider supply (2.7–36 V), no POR, ±15 V output swing capability | Better suited for high-voltage industrial analog front-ends, not optimized for ultra-low-power automotive domains | Choose LM7322QDRQ1 only if extended supply range or higher output drive is mandatory and power budget allows |
Compared with TLV9022QDRQ1, TLV9032QDRQ1 eliminates external pull-ups and simplifies layout; versus LM7322QDRQ1, it reduces quiescent current by 99% and adds POR - critical for ASIL-B–aligned power management subsystems.

FAQ
What is the maximum input voltage the TLV9032QDRQ1 can tolerate relative to its supply rails?
The TLV9032QDRQ1 features fault-tolerant inputs rated from –0.3 V to 6 V referenced to V−, independent of the supply voltage. This means inputs may safely exceed V+ (e.g., 12 V on a 5 V-powered device) without damage or phase inversion - enabling direct connection to unregulated automotive signals like LIN bus or sensor outputs without external clamping.
Does the TLV9032QDRQ1 require external pull-up resistors on its outputs?
No. The TLV9032QDRQ1 has push-pull outputs that actively drive both high and low states, eliminating the need for external pull-up resistors. This simplifies PCB layout, reduces component count, and improves rise/fall times compared to open-drain alternatives - especially beneficial in space-constrained automotive modules.
How does the Power-On Reset (POR) function improve system reliability in automotive applications?
The POR circuit in the TLV9032QDRQ1 holds outputs in a known state (low for both channels) until the supply reaches 1.65 V, preventing undefined transitions during cold cranking or battery recovery. This avoids false triggering of downstream logic or actuators - a critical requirement for ISO 26262 ASIL-B–compliant powertrain and body control functions.
Can the TLV9032QDRQ1 operate from a 1.8 V supply while maintaining full performance specifications?
Yes. The TLV9032QDRQ1 is fully specified from 1.65 V to 5.5 V. At 1.8 V, it maintains 100 ns propagation delay (typ), ±0.3 mV input offset (typ), and 16 µA per channel quiescent current - making it ideal for low-voltage domains in modern automotive ECUs powered by buck regulators.
What package options are available for the TLV9032QDRQ1, and which is recommended for thermally demanding applications?
The TLV9032QDRQ1 is offered in SOIC (D), TSSOP (PW), VSSOP (DGK), WSON (DSG), and SOT-23-THN (DDF) packages. For thermally demanding applications, the DSG (WSON with exposed thermal pad) provides lowest RθJA (175.2 °C/W) and requires the thermal pad to be soldered directly to V− for optimal heat dissipation - essential in under-hood modules operating at 125°C ambient.
