Product details
Overview
TLV9030DBVR from Texas Instruments is a single-channel, precision rail-to-rail input comparator with push-pull output, 300 µV typical input offset voltage, 100 ns propagation delay, and 16 µA quiescent current per channel-designed for voltage monitoring in motor drives and industrial control systems operating from 1.65 V to 5.5 V.
For engineers reviewing the TLV9030DBVR datasheet, TLV9030DBVR pinout, TLV9030DBVR application, or TLV9030DBVR equivalent, key selection criteria include its fault-tolerant inputs (withstand up to 6 V), -40°C to +125°C operation, low input bias current (5 pA), and compatibility with low-voltage logic interfaces and MOSFET gate driving.
Technical Context
The TLV9030DBVR implements a high-speed, low-power comparator core with internal ESD clamps enabling ±2 kV HBM robustness and fault-tolerant inputs that remain functional even when driven 0.2 V beyond V– or 0.2 V above V+. Its push-pull output stage delivers ±4 mA drive capability at 125 mV saturation voltage, supporting direct LED or capacitive load interfacing without external pull-up.
This device belongs to the TLV903x series (push-pull) and shares architecture with TLV902x (open-drain), differing only in output stage topology and associated switching characteristics-TPD-LH is 115 ns (vs. 150 ns for open-drain variants under same conditions) and it supports sourcing/sinking without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 3.3 V, and 5 V logic and analog domains. |
| Input Offset Voltage | ±0.3 mV (typ) - ensures accurate threshold detection in precision voltage monitoring applications. |
| Propagation Delay | 100 ns (high-to-low), 115 ns (low-to-high) - supports real-time response in fast feedback loops and overcurrent protection circuits. |
| Quiescent Current | 16 µA per channel - allows battery-powered or energy-sensitive designs to maintain long standby life. |
| Input Bias Current | 5 pA - minimizes loading error on high-impedance sensor nodes and reference dividers. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive, industrial motor control, and factory automation environments. |
| Fault-Tolerant Inputs | Withstand -0.3 V to +6 V relative to V– - eliminates need for external clamping diodes in noisy or mismatched supply systems. |
Pinout & Package
TLV9030DBVR is packaged in a 5-pin SOT-23 (DBV) package measuring 1.60 mm × 2.90 mm, optimized for space-constrained PCB layouts while maintaining thermal performance (RθJA = 223.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Non-inverting input | Accepts reference or signal voltage; rail-to-rail common-mode range supports operation down to V– – 0.2 V and up to V+ + 0.2 V. |
| IN– | Inverting input | Accepts monitored voltage; matched input capacitance (2 pF diff, 3 pF common-mode) minimizes dynamic imbalance. |
| OUT | Push-pull output | Sinks or sources ≥4 mA; outputs 75–125 mV above V– (low) or below V+ (high) at 4 mA load-no external pull-up required. |
| V+ | Positive supply | Connects to main system rail (1.65–5.5 V); PSRR >75 dB ensures immunity to supply noise. |
| V– | Negative supply / ground | Reference node for all inputs and output; exposed pad (in other packages) connects here-DBV has no thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with fault tolerance | Inputs operate from V– – 0.2 V to V+ + 0.2 V and survive transient overvoltage up to 6 V-reduces BOM count by eliminating external protection. |
| 100 ns propagation delay | Enables sub-microsecond response in overvoltage lockout and fast fault detection circuits without compromising power efficiency. |
| 16 µA quiescent current | Permits continuous monitoring in always-on subsystems (e.g., battery supervision) with <1 µW static power at 1.8 V. |
| 5 pA input bias current | Preserves accuracy in high-Z resistor-divider references and piezoelectric or capacitive sensor interfaces. |
| Push-pull output stage | Drives LEDs directly or switches MOSFET gates without pull-up resistors-simplifies layout and improves rise/fall time consistency. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9030DCKR | Identical electrical specs; SC-70 (DCK) package (1.25 mm × 2.00 mm) - 25% smaller footprint than DBV. | Preferred where board area is constrained; thermal resistance higher (RθJA = 238.5°C/W vs. 223.7°C/W), limiting max ambient in high-power density layouts. | Select DCKR for ultra-compact designs with adequate airflow; choose DBVR for better thermal margin in enclosed enclosures. |
| LMV331M5X | Higher offset (±2 mV), slower propagation (300 ns), higher IQ (25 µA); open-drain output requires external pull-up. | Lower cost alternative for non-critical thresholds; unsuitable for push-pull loads like LEDs or gate drivers without added components. | Use LMV331M5X only when speed, precision, and output drive are secondary to BOM cost reduction. |
Compared with TLV9030DCKR, TLV9030DBVR offers lower thermal resistance for improved reliability in thermally dense layouts; compared with LMV331M5X, it delivers 3× faster response, 6× lower offset, and integrated push-pull drive-justifying its use in safety-critical or high-performance monitoring.

FAQ
What is the maximum input voltage the TLV9030DBVR can tolerate without damage?
The TLV9030DBVR input pins (IN+ and IN–) tolerate voltages from -0.3 V to +6 V relative to V–, independent of the supply rails. This fault-tolerance eliminates external clamping diodes in systems with transient overvoltages or supply sequencing mismatches-verified per absolute maximum ratings in the official datasheet.
Does the TLV9030DBVR require an external pull-up resistor on its output?
No, the TLV9030DBVR features a push-pull output stage capable of both sourcing and sinking current. It drives high (to within 125 mV of V+) and low (to within 125 mV of V–) without external components-unlike open-drain comparators such as TLV9020DBVR, which require a pull-up resistor.
What is the typical input offset voltage drift over temperature for TLV9030DBVR?
The TLV9030DBVR exhibits ±0.5 µV/°C input offset voltage drift across -40°C to +125°C, contributing to stable threshold accuracy in thermally varying environments-critical for applications like battery cell voltage monitoring where drift-induced false triggers must be avoided.
Can TLV9030DBVR operate from a 1.8 V supply?
Yes, TLV9030DBVR is fully specified from 1.65 V to 5.5 V supply range. At 1.8 V, it maintains 100 ns propagation delay, ±0.3 mV offset, and 16 µA quiescent current-making it suitable for modern low-voltage microcontroller systems and energy-harvesting applications.
How does the TLV9030DBVR differ from TLV9020DBVR in output behavior?
The TLV9030DBVR uses a push-pull output that actively drives both logic high and low states, while TLV9020DBVR uses an open-drain output requiring an external pull-up. This makes TLV9030DBVR ideal for driving LEDs or MOSFET gates directly, whereas TLV9020DBVR suits wired-OR logic or level translation with flexible pull-up voltage.
