Product details
Overview
LM2901VQPWRG4Q1 from Texas Instruments is an AEC-Q100 Grade 1 qualified quad open-drain automotive comparator with 2 V to 32 V supply range, ±0.37 mV typical input offset voltage, 3.5 nA typical input bias current, and 1 µs typical propagation delay. It operates across –40°C to +125°C ambient and serves in HEV/EV powertrain voltage monitoring, body control module threshold detection, and infotainment system level-shifting interfaces.
For engineers reviewing the LM2901VQPWRG4Q1 datasheet, LM2901VQPWRG4Q1 pinout, LM2901VQPWRG4Q1 application, or LM2901VQPWRG4Q1 equivalent, key selection criteria include its 32 V max supply rating (distinct from LM2901B-Q1's 36 V), guaranteed operation down to 2 V, open-drain output compatibility with TTL/MOS/CMOS logic families, and qualification for automotive safety-critical subsystems requiring functional safety documentation support.
Technical Context
The LM2901VQPWRG4Q1 implements four independent PNP Darlington-pair input comparators, enabling high gain (>200 V/mV) and low input bias current while supporting common-mode input voltages from ground to VCC – 2.0 V over temperature. Its open-drain NPN output stage allows flexible pull-up configuration and wired-AND logic implementation.
Designed for automotive environments, it features ±2000 V HBM ESD protection, AEC-Q100 Class 2 CDM rating, and thermal performance validated for TSSOP-14 package (RθJA = 136.6°C/W). The "V" suffix denotes 32 V absolute maximum supply voltage and improved offset voltage vs. legacy LM2901-Q1 variants.
Key Specifications

Pinout & Package
TSSOP-14 package (4.40 mm × 5.00 mm body size) with exposed pad not connected internally; requires PCB thermal pad connection to GND for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT2) | Comparator 1 output | Open-drain NPN sink - must be pulled up externally to define logic HIGH level and interface with MCU GPIO or logic family |
| 2 (OUT1) | Comparator 2 output | Independent open-drain output - enables parallel or cascaded comparator configurations without contention |
| 3 (VCC) | Positive supply | Accepts 2–32 V DC - powers all four comparators; decoupling capacitor required within 10 mm of pin |
| 4 (IN2–) | Comparator 1 inverting input | Darlington-pair PNP input - supports common-mode down to ground; tolerates inputs up to VCC |
| 5 (IN2+) | Comparator 1 non-inverting input | Same input structure as IN2– - differential pair enables precise voltage window or threshold comparison |
| 6 (IN1–) | Comparator 2 inverting input | Electrically identical to IN2– - channel naming follows TI convention; functionally interchangeable per comparator |
| 7 (IN1+) | Comparator 2 non-inverting input | Paired with IN1– for second independent comparison - no internal cross-talk between channels |
| 8 (IN3–) | Comparator 3 inverting input | Third independent input pair - supports multi-threshold detection (e.g., battery SOC stages) |
| 9 (IN3+) | Comparator 3 non-inverting input | Enables simultaneous evaluation of three voltage conditions - reduces component count in BMS designs |
| 10 (IN4–) | Comparator 4 inverting input | Fourth independent input - allows full quad utilization in complex state-machine supervision |
| 11 (IN4+) | Comparator 4 non-inverting input | Completes quad set - supports redundant sensing or dual-fault detection architectures |
| 12 (GND) | Negative supply reference | Return path for all comparators and internal bias - must connect to system ground plane with low-inductance trace |
| 13 (OUT4) | Comparator 4 output | Final open-drain output - matches electrical behavior of OUT1–OUT3; supports same pull-up configurations |
| 14 (OUT3) | Comparator 3 output | Third open-drain output - enables independent control of separate loads (e.g., warning lamps, relays) |

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 | 36 V max supply, ±0.37 mV offset, 2 kV HBM ESD - higher voltage headroom but identical pinout and thermal profile | Preferred for 48 V mild-hybrid systems or industrial 36 V rails where extended supply range is mandatory | Select when >32 V operation is required; drop-in replacement in TSSOP-14 footprint with no layout change |
| TL331QDBVRQ1 | Single-channel, SOT-23-5, 2–36 V supply, 1.3 µs response - smaller footprint but requires four devices for quad functionality | Suitable for space-constrained modules where channel density is less critical than board area (e.g., sensor nodes) | Choose when modularity, testability per channel, or minimal PCB area outweighs cost-per-comparator efficiency |
Compared with LM2901BQPWRQ1, LM2901VQPWRG4Q1 trades 4 V supply headroom for tighter production offset distribution in 32 V systems; versus TL331QDBVRQ1, it delivers four matched channels in one package, reducing inter-channel skew and calibration complexity in multi-threshold detection.

Does LM2901VQPWRG4Q1 support operation down to 2 V supply?
Yes, LM2901VQPWRG4Q1 is specified to operate from 2 V to 32 V supply voltage, per Recommended Operating Conditions (Section 5.5). This enables direct interfacing with low-voltage microcontrollers and battery monitoring circuits in energy-efficient automotive subsystems without level-shifting circuitry.
What is the input offset voltage specification for LM2901VQPWRG4Q1 over temperature?
The LM2901VQPWRG4Q1 has a maximum input offset voltage of ±5.5 mV across the full AEC-Q100 Grade 1 temperature range (–40°C to +125°C), as documented in Section 5.7 Electrical Characteristics. Typical offset is ±0.37 mV at 25°C, making it suitable for precision threshold detection in safety-critical automotive functions.
