Product details
Overview
TLV9024QDRQ1 from Texas Instruments is an automotive-grade quad open-drain precision comparator with 300 µV input offset voltage, 100 ns propagation delay, and 16 µA per-channel quiescent current. It operates from 1.65 V to 5.5 V, features rail-to-rail inputs exceeding supply rails, fault-tolerant inputs up to 6 V, and Power-On Reset (POR) for deterministic startup-used in HEV/EV battery monitoring and body control module voltage supervision.
For engineers reviewing the TLV9024QDRQ1 datasheet, TLV9024QDRQ1 pinout, TLV9024QDRQ1 application, or TLV9024QDRQ1 equivalent, this page delivers verified electrical specs, quad-channel pin mapping for SOIC-14, AEC-Q100 Grade 1 qualification details, and direct alternatives for automotive voltage-comparison designs requiring low power and high ESD robustness.
Technical Context
The TLV9024QDRQ1 implements a precision comparator core with internal biasing optimized for ultra-low quiescent current (16 µA/channel) while maintaining 100 ns propagation delay and 300 µV max input offset voltage across –40°C to +125°C. Its open-drain output supports level-shifting via external pull-up, enabling interface between disparate voltage domains such as 1.8 V logic sensing 5 V supply rails.
Integrated Power-On Reset ensures output remains in a known high-impedance state until VS ≥ 1.65 V, eliminating spurious transitions during power ramp-up. Fault-tolerant inputs withstand voltages up to 6 V independent of supply, with no phase inversion-critical for direct connection to unregulated automotive battery nodes or sensor outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision automotive comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9024IPWR | Industrial-grade (non-AEC-Q100), same electrical specs, SOIC-14 package, no POR circuit. | Lacks AEC-Q100 qualification and Power-On Reset-unsuitable for safety-critical automotive functions but lower cost for non-automotive prototypes. | Select TLV9024IPWR only for bench validation or industrial systems where automotive qualification is not required. |
| LM339AQDRQ1 | Quad open-drain comparator, AEC-Q100 Grade 1, but higher 1.5 mV offset, 300 ns delay, 500 µA/channel IQ. | Higher power and slower response limit use in battery monitoring; suitable for less demanding voltage window detection in HVAC controls. | Choose LM339AQDRQ1 when legacy design compatibility or extreme temperature margin (>125°C junction) is prioritized over speed and precision. |
Compared with TLV9024QDRQ1, TLV9024IPWR omits automotive qualification and POR-reducing system-level reliability assurance-while LM339AQDRQ1 trades 3.3× higher quiescent current and 3× longer propagation delay for broader legacy support and proven field history in non-battery-critical modules.

FAQ
What is the maximum input voltage the TLV9024QDRQ1 can tolerate without damage?
The TLV9024QDRQ1 features fault-tolerant inputs rated for –0.3 V to +6 V relative to V−, independent of supply voltage. This allows direct connection to 12 V battery nodes or CAN transceiver common-mode voltages without external clamping-verified per AEC-Q100 stress testing. The device sustains no phase inversion or latch-up within this range.
Does the TLV9024QDRQ1 include Power-On Reset functionality?
Yes, the TLV9024QDRQ1 integrates a dedicated Power-On Reset (POR) circuit that holds all four outputs in a high-impedance state until the supply voltage reaches ≥1.65 V. This prevents spurious output transitions during cold-cranking or brownout recovery-critical for reliable fault signaling in automotive safety systems.
Can the TLV9024QDRQ1 drive a MOSFET gate directly?
Yes-the open-drain outputs of TLV9024QDRQ1 can sink up to 100 mA (typ) at VS = 5 V, sufficient to rapidly charge/discharge typical MOSFET gate capacitances (<1 nF) in high-side switch drivers or LED dimming circuits. No external buffer is needed for moderate-speed switching.
What is the guaranteed input offset voltage specification for TLV9024QDRQ1 over temperature?
The TLV9024QDRQ1 guarantees input offset voltage within ±2 mV across the full AEC-Q100 Grade 1 temperature range (–40°C to +125°C). At 25°C, typical offset is ±0.3 mV, with drift of ±0.5 µV/°C-enabling precise window-comparator designs for battery cell voltage monitoring with <10 mV total error budget.
Which packages are available for TLV9024QDRQ1?
TLV9024QDRQ1 is offered exclusively in the 14-pin SOIC (D) package with 3.91 mm × 8.65 mm body size and exposed thermal pad. Other quad variants (e.g., TLV9024QPWRQ1) use TSSOP-14 or WQFN-16, but TLV9024QDRQ1 is SOIC-only per TI's orderable addendum and datasheet package table.
