Product details
Overview
TLV9034QDRQ1 from Texas Instruments is a quad-channel automotive-grade precision comparator with push-pull output, 100 ns propagation delay, ±0.3 mV input offset voltage (typ), and 16 µA per channel quiescent current. It operates from 1.65 V to 5.5 V and supports rail-to-rail inputs exceeding supply rails-used in HEV/EV battery monitoring and body control module voltage supervision.
For engineers reviewing the TLV9034QDRQ1 datasheet, TLV9034QDRQ1 pinout, TLV9034QDRQ1 application, or TLV9034QDRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (–40°C to +125°C), fault-tolerant inputs (up to 6 V), Power-On Reset (POR) for deterministic startup, and quad-channel push-pull drive capability for direct LED or MOSFET gate interfacing.
Technical Context
The TLV9034QDRQ1 implements a high-speed, low-power comparator core with internal POR circuitry ensuring output remains in a known state until VS ≥ 1.65 V, eliminating power-up transients. Its input stage features ESD-hardened, fault-tolerant architecture allowing IN+ and IN− to withstand voltages up to 6 V independent of supply rails without phase inversion or damage.
As a push-pull variant in the TLV903x-Q1 family, it delivers symmetrical sourcing/sinking capability (≥90 mA short-circuit current), enabling direct interface with capacitive loads (e.g., MOSFET gates) or indicator LEDs without external pull-up resistors-unlike open-drain counterparts requiring external biasing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision automotive comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9034DR | Industrial-grade (non-AEC-Q100); same electrical specs but no automotive qualification or extended temp screening. | Not suitable for production automotive ECUs; acceptable for prototyping or non-safety automotive accessories. | Select TLV9034DR only for cost-sensitive non-automotive designs where AEC-Q100 is not mandated. |
| LM339QDRQ1 | Quad open-drain comparator; higher 1.5 mV offset, slower 300 ns propagation, no POR, no fault-tolerant inputs. | Lacks push-pull drive and deterministic startup; requires external pull-ups and additional conditioning for robust automotive use. | Choose LM339QDRQ1 only when legacy compatibility or ultra-low cost outweighs speed, precision, and integrated POR needs. |
Compared with TLV9034DR and LM339QDRQ1, TLV9034QDRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 100 ns speed, ±0.3 mV offset, and integrated POR-making it the only option for new automotive designs requiring both precision and functional safety readiness.

FAQ
What is the maximum input voltage tolerance for TLV9034QDRQ1 inputs?
The TLV9034QDRQ1 inputs tolerate voltages from –0.3 V to 6 V relative to V−, independent of the supply voltage. This fault-tolerant design allows direct connection to unregulated battery nodes or sensors exceeding the 1.65–5.5 V supply range without damage or output inversion-critical for automotive battery monitoring and load-dump resilience.
Does TLV9034QDRQ1 include Power-On Reset functionality?
Yes, TLV9034QDRQ1 integrates a dedicated Power-On Reset (POR) circuit that holds outputs in a known state until the supply voltage reaches the minimum operating threshold (1.65 V). This prevents undefined output transitions during power ramp-up or brownout conditions-essential for deterministic behavior in automotive control units and safety-critical subsystems.
What package options are available for TLV9034QDRQ1?
TLV9034QDRQ1 is offered in a 14-pin SOIC (D) package with nominal dimensions 3.91 mm × 8.65 mm. This leaded, surface-mount package supports standard reflow profiles, provides robust thermal performance (RθJA = 136.0°C/W), and includes an exposed thermal pad that must be connected directly to the V− pin for optimal reliability and EMI suppression.
Can TLV9034QDRQ1 drive MOSFET gates directly?
Yes, TLV9034QDRQ1's push-pull output can source and sink ≥90 mA, enabling direct drive of power MOSFET gates without external buffers. Its 100 ns propagation delay and rail-to-rail input support fast, precise timing in gate-drive supervision and fault-lockout circuits-common in inverter and DC-DC converter control stages.
How does TLV9034QDRQ1 differ from TLV9024QDRQ1?
TLV9034QDRQ1 features push-pull outputs for bidirectional drive capability, while TLV9024QDRQ1 uses open-drain outputs requiring external pull-up resistors. Both share identical precision specs (±0.3 mV offset, 100 ns delay, AEC-Q100 Grade 1), but TLV9034QDRQ1 eliminates external components for logic-level interfacing and capacitive load driving-reducing BOM count and layout complexity.
