Product details
Overview
TLV9032QDGKRQ1 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) and Power-On Reset for deterministic startup in HEV/EV powertrain monitoring.
For engineers reviewing the TLV9032QDGKRQ1 datasheet, TLV9032QDGKRQ1 pinout, TLV9032QDGKRQ1 application, or TLV9032QDGKRQ1 equivalent, this page delivers verified electrical specs, dual-comparator pin mapping for DGK package, automotive-grade thermal performance data, and validated alternatives for body control module and infotainment voltage supervision designs.
Technical Context
The TLV9032QDGKRQ1 implements a rail-to-rail input stage with fault-tolerant clamping that withstands input voltages up to 6 V regardless of supply, preventing phase inversion during transients. Its internal Power-On Reset circuit holds outputs in a known state until VS ≥ 1.65 V, eliminating spurious switching at power-up.
As a push-pull output variant in the TLV903x-Q1 family, it sources/sinks >90 mA short-circuit current and drives capacitive loads (e.g., MOSFET gates) without external pull-ups. The 2 pF differential input capacitance and 5 pA bias current support high-impedance sensing in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface with 1.8 V, 3.3 V, and 5 V automotive microcontrollers and sensors. |
| Input Offset Voltage | ±0.3 mV (typ) - Enables precise threshold detection in battery voltage monitoring and overvoltage protection circuits. |
| Propagation Delay | 100 ns (high-to-low, typ) - Supports fast response in motor phase detection and safety-critical window comparators. |
| Quiescent Current | 16 µA per channel (typ) - Allows always-on voltage supervision in low-power body control modules without compromising battery life. |
| Input Voltage Range | (V−) − 0.2 V to (V+) + 0.2 V - Permits operation beyond supply rails for robust signal conditioning in noisy powertrain systems. |
| Output Drive Strength | 90 mA sink/source (short-circuit) - Directly drives LEDs, relays, or MOSFET gates without external buffers in cluster display backlight control. |
| Ambient Temperature Range | –40°C to +125°C - Qualified for under-hood and transmission control unit deployment per AEC-Q100 Grade 1. |
Pinout & Package
DGK package: 8-pin VSSOP (3.00 mm × 3.00 mm), lead-free, RoHS-compliant, with exposed thermal pad connected directly to V−.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT1 | Output of Comparator 1 | Push-pull output capable of sourcing/sinking >90 mA; no external pull-up required for logic-level interfacing. |
| 2: IN1− | Inverting Input of Comparator 1 | Fault-tolerant input rated to 6 V; accepts signals beyond V+ or below V− without damage or inversion. |
| 3: IN1+ | Noninverting Input of Comparator 1 | Rail-to-rail input stage enables accurate sensing of signals near supply rails in battery monitoring. |
| 4: V− | Negative Supply Rail | Reference node for all inputs and outputs; thermal pad must be soldered to PCB ground plane for thermal management. |
| 5: IN2+ | Noninverting Input of Comparator 2 | Independent channel for dual-threshold detection (e.g., window comparator for HVAC fan speed control). |
| 6: IN2− | Inverting Input of Comparator 2 | Matches IN1− in ESD rating (2 kV HBM), enabling matched differential sensing in infotainment audio biasing. |
| 7: OUT2 | Output of Comparator 2 | Electrically identical to OUT1; supports independent logic-level output for redundant safety monitoring paths. |
| 8: V+ | Positive Supply Rail | Accepts 1.65–5.5 V; PSRR of 75–95 dB suppresses supply noise in engine control unit power domains. |
Key Features

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 |
|---|---|---|---|
| TLV9032DR | Industrial-grade (non-AEC-Q100), same electrical specs but rated only to 125°C junction (not ambient), no automotive qualification testing. | Not suitable for safety-critical automotive functions; acceptable for industrial motor drives or test equipment. | Select TLV9032DR only when AEC-Q100 Grade 1 compliance is not required and cost optimization is prioritized. |
| LM393BQDGKRQ1 | Higher 1.5 mV max offset, 300 ns propagation delay, 40 µA per channel IQ, open-drain only output. | Lacks push-pull drive and POR; requires external pull-up; less suitable for direct MOSFET gate driving or deterministic startup. | Choose LM393BQDGKRQ1 when lower cost is critical and system design accommodates slower response and external biasing. |
Compared with TLV9032DR and LM393BQDGKRQ1, the TLV9032QDGKRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 100 ns speed, push-pull output, and POR in a single VSSOP package-enabling compact, fail-safe voltage monitoring in modern automotive ECUs without design compromises.

FAQ
What is the maximum input voltage tolerance for TLV9032QDGKRQ1?
The TLV9032QDGKRQ1 supports input voltages from –0.3 V to 6 V relative to V−, independent of supply voltage. This fault-tolerant capability allows direct connection to 12 V or 48 V automotive buses without external clamping, and prevents output phase inversion during transients such as load dump or jump-start events. Confirmed per Absolute Maximum Ratings table in SNOSDA9E Rev. May 2024.
Does TLV9032QDGKRQ1 require external pull-up resistors on its outputs?
No, TLV9032QDGKRQ1 does not require external pull-up resistors because it features push-pull outputs on both channels. Each output can actively source and sink current (≥90 mA short-circuit), enabling direct interface with CMOS logic, LEDs, or MOSFET gates. This eliminates BOM cost and board space associated with pull-up resistors-confirmed in the Functional Block Diagram and Output section of the datasheet.
How does the Power-On Reset (POR) function in TLV9032QDGKRQ1 improve system reliability?
The POR circuit in TLV9032QDGKRQ1 holds both outputs in a defined low state until the supply voltage reaches ≥1.65 V, preventing undefined or oscillating outputs during slow-ramp power-up (e.g., cold-cranking). This eliminates false triggering of downstream logic or safety relays, ensuring deterministic behavior in automotive ECUs. Verified in Section 6.3 and Figure 6-1 of SNOSDA9E.
Can TLV9032QDGKRQ1 operate from a 1.8 V supply while maintaining full functionality?
Yes, TLV9032QDGKRQ1 operates fully across 1.65 V to 5.5 V supply range. At 1.8 V, it maintains 100 ns propagation delay (typ), ±0.3 mV offset voltage (typ), and 16 µA per channel quiescent current-enabling compatibility with low-voltage microcontrollers and sensors in next-generation automotive domains. All specifications are tested and guaranteed per Recommended Operating Conditions (Section 5.3).
What is the thermal pad connection requirement for TLV9032QDGKRQ1 in DGK package?
The exposed thermal pad on the TLV9032QDGKRQ1 DGK package must be soldered directly to the V− (ground) plane on the PCB. This connection is mandatory for thermal performance and electrical stability, as specified in Pin Functions Table 4-2 and Layout Guidelines (Section 8.1). Failure to connect the pad degrades junction-to-board thermal resistance by >50% and risks output instability under load.
