Product details
Overview
LM2901VQPWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified quad open-drain automotive comparator operating from 2 V to 32 V supply, with ±0.37 mV typical input offset voltage, 3.5 nA typical input bias current, and 1 µs typical propagation delay at 5 V. It serves as a precision voltage comparison engine in HEV/EV powertrain monitoring circuits where rail-to-rail input common-mode range and robust ESD immunity are required.
For engineers reviewing the LM2901VQPWRQ1 datasheet, LM2901VQPWRQ1 pinout, LM2901VQPWRQ1 application, or LM2901VQPWRQ1 equivalent, this page delivers verified electrical specifications, TSSOP-14 package details, automotive-grade thermal performance data, functional safety documentation support, and validated alternative comparators for design-in continuity.
Technical Context
The LM2901VQPWRQ1 implements four independent PNP Darlington-pair input comparators with open-drain NPN outputs, enabling wired-AND logic and flexible level-shifting across supply domains. Its input stage supports common-mode voltages from ground to VCC − 2.0 V over −40°C to +125°C.
It features dedicated ESD protection on all pins (±2000 V HBM), operates with single or dual supplies (ΔVCC ≤ 36 V), and maintains stable quiescent current (0.8–1.6 mA total) across 5 V to 36 V supply range - critical for battery-supplied automotive subsystems requiring low standby power.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2901BQPWRQ1 | Wider 2–36 V supply range; ±0.37 mV offset same; improved 2 kV HBM ESD on all pins | Preferred for 24 V commercial vehicle systems or designs requiring maximum supply headroom | Select when operating above 32 V or needing enhanced ESD robustness beyond AEC-Q100 Class 2 baseline |
| TL331QDBVRQ1 | Single-channel, SOT-23-5; 2–36 V supply; 1.3 µs response; ±7 mV max offset | Used where space-constrained PCBs require minimal footprint and only one comparator is needed | Choose for point-of-load supervision or compact modules where quad integration is unnecessary |
Compared with LM2901BQPWRQ1, the LM2901VQPWRQ1 trades 4 V supply headroom for tighter qualification alignment with 32 V automotive architectures; versus TL331QDBVRQ1, it delivers four-fold channel density at the cost of larger TSSOP-14 footprint - optimizing for multi-rail monitoring rather than ultra-miniaturization.

FAQ
What is the maximum supply voltage for LM2901VQPWRQ1?
The LM2901VQPWRQ1 supports a maximum supply voltage of 32 V, as specified in its recommended operating conditions. This rating applies across the full −40°C to +125°C ambient temperature range and aligns with 24 V automotive system requirements including load-dump transients. Exceeding 32 V risks violating absolute maximum ratings and may cause permanent damage.
Does LM2901VQPWRQ1 support rail-to-rail input operation?
Yes, the LM2901VQPWRQ1 supports rail-to-rail input common-mode voltage operation from ground (V−) up to VCC − 2.0 V over temperature. This allows direct connection to low-side current sense resistors and battery terminals without level-shifting circuitry, while maintaining valid comparator output states even when one input exceeds VCC.
What is the output configuration of LM2901VQPWRQ1?
The LM2901VQPWRQ1 features four independent open-drain NPN outputs. Each output sinks current when its associated comparator's inverting input voltage exceeds the non-inverting input voltage by more than the offset voltage. External pull-up resistors are required to establish logic-high voltage levels compatible with downstream TTL, CMOS, or microcontroller inputs.
Is LM2901VQPWRQ1 qualified for functional safety applications?
Yes, LM2901VQPWRQ1 is functional safety-capable with documentation available to aid ISO 26262 system design. Texas Instruments provides FIT rate data, failure mode effect analysis (FMEA), and diagnostic coverage metrics supporting ASIL-B development - enabling use in automotive safety-related systems like battery disconnect control and motor overcurrent protection.
How does LM2901VQPWRQ1 differ from standard LM2901-Q1?
The LM2901VQPWRQ1 is the "V" variant of the LM2901x-Q1 family, rated for 32 V maximum supply voltage (versus 30 V for base LM2901-Q1) and optimized for automotive applications requiring extended voltage headroom. It shares the same TSSOP-14 package, AEC-Q100 Grade 1 qualification, and key specs like ±5.5 mV max offset and 1 µs propagation delay, but excludes the enhanced 2 kV HBM ESD of the "B" variant.
