Product details
Overview
TLV9032QPWRQ1 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 - used in HEV/EV battery monitoring and body control module voltage supervision.
For engineers reviewing the TLV9032QPWRQ1 datasheet, TLV9032QPWRQ1 pinout, TLV9032QPWRQ1 application, or TLV9032QPWRQ1 equivalent, key selection criteria include its push-pull output drive capability (±100 mA short-circuit current), guaranteed startup behavior via POR, automotive-grade ESD robustness (2 kV HBM), and compatibility with low-voltage logic interfaces in safety-critical powertrain subsystems.
Technical Context
The TLV9032QPWRQ1 implements a high-speed, low-power comparator core with internal biasing optimized for stable operation across automotive temperature extremes. Its fault-tolerant input stage accepts voltages up to 6 V independent of supply rails, eliminating external clamping in noisy 12 V/48 V systems.
Power-On Reset ensures deterministic output state during ramp-up/down of supply voltage, preventing spurious transitions in critical monitoring paths. The push-pull output delivers symmetrical sourcing/sinking capability (75 mV VOL / VOH at 4 mA) without requiring external pull-up resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 3.3 V, and 5 V microcontrollers and sensors. |
| Input Offset Voltage | ±0.3 mV (typ) - enables accurate threshold detection in battery cell voltage monitoring with <10 mV error budget. |
| Propagation Delay | 100 ns (high-to-low, typ) - suitable for fast overvoltage/undervoltage response in DC-DC converter protection circuits. |
| Quiescent Current | 16 µA per channel - allows always-on monitoring in low-power wake-up domains of automotive ECUs. |
| Input Common-Mode Range | (V−) − 0.2 V to (V+) + 0.2 V - supports rail-to-rail sensing and overvoltage tolerance beyond supply rails. |
| Output Drive Strength | ±100 mA short-circuit current - directly drives LEDs, MOSFET gates, or small relays without external buffers. |
| Ambient Temperature Range | –40°C to +125°C - qualified for engine bay, powertrain, and ADAS module deployment per AEC-Q100 Grade 1. |
Pinout & Package
TLV9032QPWRQ1 is packaged in an 8-pin TSSOP (PW) with 3.00 mm × 4.40 mm body size and exposed thermal pad connected to V−.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 | Comparator 1 output | Push-pull digital output capable of sourcing/sinking ≥4 mA with <125 mV saturation voltage. |
| IN1− | Inverting input of comparator 1 | Fault-tolerant analog input; withstands −0.3 V to 6 V regardless of supply voltage. |
| IN1+ | Noninverting input of comparator 1 | Rail-to-rail input stage enables direct connection to sensor outputs or divider networks. |
| V− | Negative supply terminal | Reference node for all inputs and outputs; thermal pad must be soldered directly to this pin. |
| IN2+ | Noninverting input of comparator 2 | Independent second channel for dual-threshold detection (e.g., window comparator configuration). |
| IN2− | Inverting input of comparator 2 | Matches IN1− specs - identical fault tolerance and common-mode range. |
| OUT2 | Comparator 2 output | Functionally identical to OUT1; enables concurrent monitoring of two independent signals. |
| V+ | Positive supply terminal | Accepts 1.65 V to 5.5 V; PSRR >75 dB ensures immunity to supply ripple in noisy automotive environments. |
Key Features
| Feature | Design Value |
|---|---|
| Power-On Reset (POR) | Guarantees known output state until V+ reaches minimum operating voltage - eliminates power-up glitches in safety-critical monitoring. |
| Fault-Tolerant Inputs | Withstand −0.3 V to 6 V input voltage regardless of V+ or V− - removes need for external clamping diodes in 12 V system interfaces. |
| Push-Pull Output | Eliminates external pull-up resistors and supports bidirectional driving of capacitive loads (e.g., MOSFET gates) and indicator LEDs. |
| Low Input Bias Current | 5 pA (typ) - minimizes loading error in high-impedance voltage divider networks used for battery pack cell monitoring. |
| AEC-Q100 Grade 1 Qualification | Validated for −40°C to +125°C ambient operation with HBM ESD level 2 and CDM level C6 - meets automotive functional safety requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9032IDR | Industrial-grade (non-AEC-Q100), same electrical specs but rated only to –40°C to +125°C junction (not ambient), no automotive qualification testing. | Lacks AEC-Q100 Grade 1 validation; unsuitable for safety-critical automotive functions requiring traceable qualification. | Select TLV9032IDR only for non-automotive industrial or consumer applications where automotive qualification is not required. |
| LM393BQDRQ1 | Higher input offset (±1.7 mV), slower propagation (300 ns typ), open-drain only, no POR, but supports wider supply (2.0 V to 36 V). | Better suited for high-voltage industrial sensing; lacks precision and deterministic startup needed for battery cell monitoring. | Choose LM393BQDRQ1 when interfacing to >5.5 V sources or when cost sensitivity outweighs speed/accuracy requirements. |
Compared with TLV9032IDR and LM393BQDRQ1, TLV9032QPWRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 100 ns speed, 300 µV offset, and POR - making it the only option qualified for precision, fast-response voltage supervision in automotive powertrain and ADAS subsystems.

FAQ
What is the maximum input voltage the TLV9032QPWRQ1 can tolerate relative to its supply rails?
The TLV9032QPWRQ1 features fault-tolerant inputs rated from –0.3 V to 6 V referenced to V−, independent of the V+ supply voltage. This allows direct connection to 12 V or 48 V automotive subsystems without external clamping, provided input current is limited to ≤10 mA. This specification is validated per AEC-Q100 stress testing.
Does the TLV9032QPWRQ1 require external pull-up resistors on its outputs?
No. The TLV9032QPWRQ1 has a push-pull output stage that actively sources and sinks current - unlike open-drain comparators, it does not require external pull-up resistors. This simplifies PCB layout and enables direct driving of LEDs, MOSFET gates, or MCU interrupt pins with defined logic levels across the full supply range.
How does the Power-On Reset (POR) function improve system reliability in automotive applications?
The POR circuit in TLV9032QPWRQ1 holds both outputs in a known low state until V+ rises above the minimum operating voltage (1.65 V). This prevents undefined or metastable output states during power-up/power-down sequences - critical for avoiding false fault assertions in battery management or power sequencing logic where transient glitches could trigger unsafe shutdowns.
Can the TLV9032QPWRQ1 operate from a 1.8 V supply while maintaining full performance specifications?
Yes. TLV9032QPWRQ1 is fully specified from 1.65 V to 5.5 V supply. At 1.8 V, it maintains 100 ns typical propagation delay, ±0.3 mV input offset voltage, and 16 µA per channel quiescent current - enabling integration into ultra-low-power automotive subsystems such as always-on wake-up monitors and sensor hubs.
Is the TLV9032QPWRQ1 pin-compatible with other devices in the TLV90xx-Q1 family?
TLV9032QPWRQ1 shares the same 8-pin TSSOP (PW) package pinout with TLV9022QPWRQ1 (open-drain dual), but differs in output stage behavior. While pin assignments match, substituting TLV9032QPWRQ1 for TLV9022QPWRQ1 requires verifying downstream logic compatibility due to push-pull vs. open-drain drive characteristics - no PCB changes are needed, but system-level timing and load interface must be revalidated.
