Product details
Overview
LM2901VQPWRG4 from Texas Instruments is a quad differential comparator IC designed for single-supply operation across 2 V to 36 V, featuring ±0.37 mV typical input offset voltage, 1 µs propagation delay, 2 kV HBM ESD rating, and rail-to-rail input capability down to ground - used in motor drive fault detection, server PSU overvoltage monitoring, and industrial sensor signal conditioning.
For engineers reviewing the LM2901VQPWRG4 datasheet, LM2901VQPWRG4 pinout, LM2901VQPWRG4 application, or LM2901VQPWRG4 equivalent, key selection criteria include its extended –40°C to +125°C operating range, 3.5 nA typical input bias current, open-collector output compatibility with TTL/MOS/CMOS, and drop-in replacement capability for legacy LM2901 variants without layout changes.
Technical Context
The LM2901VQPWRG4 implements four independent comparators with internal ESD clamps enabling 2 kV HBM robustness, common-mode input range extending to ground and up to VCC – 2 V, and differential input voltage tolerance of ±38 V. Its open-collector outputs require external pull-up resistors and support wired-OR logic configurations.
Designed as the B-version upgrade of the LM2901 family, it delivers improved performance over non-B variants: lower offset (±0.37 mV vs. ±15 mV max), faster response (1 µs vs. 1.3 µs), reduced supply current (0.8–1.2 mA total vs. 1–2.5 mA), and enhanced input ruggedness - all while maintaining full functional and pinout compatibility with LM2901, LM2901V, and LM2901AV.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2901QPWRQ1 | Automotive AEC-Q100 Grade 1 (–40°C to +125°C), same electrical specs but qualified for automotive use | Required for ADAS, body control modules, and infotainment power management where automotive qualification is mandated | Select LM2901QPWRQ1 when ISO/TS 16949-compliant sourcing and PPAP documentation are required |
| LM339BDR | Same B-version specs but rated for 0°C to +85°C ambient; SOIC-14 package instead of TSSOP | Suitable for commercial-grade applications like appliances and consumer infrastructure where extended temp is not needed | Choose LM339BDR for cost-sensitive, space-tolerant designs with standard temperature requirements |
Compared with LM2901VQPWRG4, LM2901QPWRQ1 adds automotive qualification without altering performance, while LM339BDR trades industrial temperature range for lower cost and larger SOIC footprint - both retain identical comparator functionality and pinout.

FAQ
What is the maximum supply voltage rating for LM2901VQPWRG4?
The LM2901VQPWRG4 has an absolute maximum supply voltage of 38 V, with recommended operating range from 2 V to 36 V. This allows direct interface with unregulated 24 V industrial rails and 36 V battery systems without external regulation, while maintaining specified performance across the full range.
Does LM2901VQPWRG4 support rail-to-rail input operation?
Yes, LM2901VQPWRG4 supports rail-to-rail common-mode input voltage from ground (V–) up to VCC – 2 V. Either input can extend to VCC without damage, and the device maintains correct output state as long as at least one input remains within the valid common-mode range - enabling direct sensing of low-side shunt voltages.
Is LM2901VQPWRG4 pin-compatible with older LM2901 variants?
Yes, LM2901VQPWRG4 is a drop-in replacement for LM2901, LM2901V, and LM2901AV in TSSOP-14 packages. It retains identical pinout, electrical interface, and functional behavior - allowing direct substitution without PCB or schematic modifications in existing designs.
What output configuration does LM2901VQPWRG4 use?
LM2901VQPWRG4 features open-collector outputs on all four comparators. Each output requires an external pull-up resistor to a logic-compatible voltage (e.g., 3.3 V or 5 V), enabling wired-OR logic, level translation, and flexible interfacing with TTL, MOS, and CMOS loads - consistent with the entire LMx39/LM2901 family.
What is the guaranteed input offset voltage specification for LM2901VQPWRG4 over temperature?
The LM2901VQPWRG4 guarantees input offset voltage of ±5.5 mV over its full operating temperature range of –40°C to +125°C. This is significantly tighter than the ±15 mV max of standard LM2901, improving accuracy in thermal-cycling applications such as motor drive current sensing and industrial temperature monitoring.
