Product details
Overview
TLV2401QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified, single-channel, rail-to-rail input/output nano-power operational amplifier designed for automotive battery monitoring and protection circuits. It delivers 880 nA typical quiescent current, 5.5 kHz gain-bandwidth product, ±1950 µV max input offset voltage, and reverse battery protection up to –18 V - enabling reliable operation in electric vehicle DC/DC converters and on-board chargers.
For engineers reviewing the TLV2401QDBVRQ1 datasheet, TLV2401QDBVRQ1 pinout, TLV2401QDBVRQ1 application, or TLV2401QDBVRQ1 equivalent, key selection criteria include ultra-low supply current at 2.5–16 V operation, input common-mode range extending 5 V beyond VCC, rail-to-rail output swing into 500 kΩ, and guaranteed performance from –40°C to 125°C.
Technical Context
The TLV2401QDBVRQ1 employs a dual-stage PNP/NPN input stage enabling rail-to-rail input operation with extended common-mode range (–0.1 V to VCC + 5 V) and robust reverse-battery tolerance. Its nano-power architecture uses precision trimming to achieve 390 µV typical offset voltage and 120 dB CMRR while maintaining 130 V/mV minimum open-loop gain at 2.7 V.
It operates across 2.5 V to 16 V supply rails with specified electrical characteristics at 2.7 V, 5 V, and 15 V - supporting Li-ion battery systems and TI MSP430/MSP432 microcontrollers. Input bias current remains below ±1000 pA (typ), enabling high-impedance sensor interfacing with megaohm-level feedback networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 16 V - supports single-supply Li-ion (2.5 V min) and 12 V automotive systems without level-shifting. |
| Quiescent Current | 880 nA/channel (typ) - enables multi-year battery life in always-on EV monitoring nodes. |
| Input Offset Voltage | ±1950 µV (max) - ensures <1 mV error in 0.5 V reference amplification for battery cell voltage sensing. |
| Gain-Bandwidth Product | 5.5 kHz - sufficient for low-frequency signal conditioning (e.g., thermistor, current-sense amp outputs). |
| Common-Mode Input Range | –0.1 V to VCC + 5 V - allows direct connection to sensors biased above supply (e.g., shunt monitors in high-side configurations). |
| Reverse Battery Protection | Withstands –18 V supply - prevents damage during incorrect battery installation in automotive modules. |
| CMRR | 120 dB (typ) - rejects power rail noise in noisy automotive environments when measuring small differential signals. |
Pinout & Package
TLV2401QDBVRQ1 is housed in a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained automotive PCBs and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Amplifier output | Rail-to-rail output capable of sourcing/sinking ±200 µA; drives 500 kΩ load with <150 mV drop at 2 µA sink. |
| V– (Pin 2) | Negative supply / ground reference | Accepts 0 V (single-supply) or negative rail; supports split supplies down to ±1.25 V. |
| IN+ (Pin 3) | Noninverting input | Part of PNP/NPN composite input stage; extends 5 V above VCC without damage or phase inversion. |
| IN– (Pin 4) | Inverting input | Matches IN+ in voltage range and bias current; enables precision difference amplification with matched external resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2401IDBVR | Non-automotive grade (industrial temp: –40°C to 85°C); identical electrical specs and pinout. | Lacks AEC-Q100 qualification and extended 125°C operation - unsuitable for powertrain or under-hood use. | Select TLV2401IDBVR only for cost-sensitive non-automotive designs where Grade 1 qualification is not required. |
| LPV821DRX | Lower quiescent current (650 nA), but narrower supply range (1.6 V–5.5 V); no reverse-battery protection. | Restricted to low-voltage battery-powered IoT sensors - cannot replace TLV2401QDBVRQ1 in 12 V automotive systems. | Choose LPV821DRX only for sub-5 V portable applications prioritizing lowest possible IQ over voltage range and ruggedness. |
Compared with TLV2401IDBVR and LPV821DRX, TLV2401QDBVRQ1 uniquely combines AEC-Q100 Grade 1 qualification, –18 V reverse-battery tolerance, and 2.5–16 V operation - making it the sole viable option for automotive battery monitoring where reliability across extreme voltage and temperature conditions is mandatory.

FAQ
What is the maximum supply voltage rating for TLV2401QDBVRQ1?
The absolute maximum supply voltage for TLV2401QDBVRQ1 is 17 V, but the recommended operating range is 2.5 V to 16 V. Operation at 16 V is fully characterized across –40°C to 125°C, with electrical specifications guaranteed at 2.7 V, 5 V, and 15 V per the datasheet. Exceeding 16 V risks permanent damage even if within the 17 V absolute maximum limit.
Does TLV2401QDBVRQ1 support true rail-to-rail input and output operation?
Yes, TLV2401QDBVRQ1 supports rail-to-rail input (–0.1 V to VCC + 5 V) and rail-to-rail output (within 150 mV of rails at 2 µA load). The input stage uses a hybrid PNP/NPN topology that maintains functionality even when inputs exceed VCC by up to 5 V - a key enabler for high-side sensing without external clamping.
How does reverse battery protection work in TLV2401QDBVRQ1?
TLV2401QDBVRQ1 incorporates internal Schottky diode protection that limits reverse supply current to <100 nA at 25°C when VCC = –18 V (inputs grounded, outputs open). This prevents latch-up or destructive current flow during incorrect battery installation. Input/output pins remain protected under reverse bias if current is limited to <10 mA via external series resistance.
What is the typical input offset voltage drift over temperature for TLV2401QDBVRQ1?
The TLV2401QDBVRQ1 exhibits ±3 µV/°C typical input offset voltage drift across –40°C to 125°C. This low drift, combined with 390 µV typical initial offset, ensures minimal total error accumulation in automotive temperature-cycling environments - critical for precision battery voltage measurement over vehicle lifetime.
Can TLV2401QDBVRQ1 drive capacitive loads directly?
TLV2401QDBVRQ1 is stable with capacitive loads up to 100 pF per the datasheet's phase margin characterization (60° at 100 pF). For larger loads (e.g., >200 pF), external isolation resistance (e.g., 100 Ω in series with output) is required to maintain stability. The device's 5.5 kHz GBW and 2.5 V/ms slew rate inherently limit high-frequency oscillation risk in typical sensor interface applications.
