Product details
Overview
TLV3012AIDBVTG4 from Texas Instruments is a push-pull output, low-power comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (at 25°C), 2–4 μs propagation delay, and operation from 1.65 V to 5.5 V supply. It features fail-safe inputs, power-on-reset, built-in hysteresis, and rail-to-rail input common-mode range extending 200 mV beyond rails - used in battery management systems and toll tag sensing circuits.
For engineers reviewing the TLV3012AIDBVTG4 datasheet, TLV3012AIDBVTG4 pinout, TLV3012AIDBVTG4 application, or TLV3012AIDBVTG4 equivalent, key selection criteria include its guaranteed sub-4 μs switching at 1.65 V, ±0.25% reference accuracy, –40°C to +125°C operating range, and SOT-23-6 package compatibility with space-constrained portable electronics designs.
Technical Context
The TLV3012AIDBVTG4 implements a precision comparator core with an on-die series voltage reference buffered to drive up to 0.5 mA load. Its internal hysteresis (2–8 mV) and power-on-reset circuit eliminate external components required for reliable startup in low-voltage microcontroller wake-up applications.
It uses a CMOS input stage enabling picoampere-level input bias current (±4.5 pA typ), and a push-pull output stage capable of sourcing/sinking 5 mA while maintaining ≤200 mV swing from rails at full temperature range - supporting direct interfacing with 1.8 V logic without pull-up resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct use with single-cell Li-ion (2.7–4.2 V), coin cell (1.65–3.0 V), and 3.3/5 V systems |
| Quiescent Current | 3.1 μA max at 25°C - supports >10-year battery life in always-on asset tracking sensors |
| Reference Voltage | 1.242 V ±0.25% - provides stable threshold for precision overvoltage/undervoltage detection without external resistor dividers |
| Propagation Delay | 2–4 μs (low-to-high & high-to-low) - meets real-time response requirements in lane departure warning signal conditioning |
| Input Common-Mode Range | (V−) − 0.2 V to (V+) + 0.2 V - allows direct sensing of signals below ground or above supply in automotive cluster applications |
| Hysteresis | 2–8 mV - suppresses chatter on noisy analog inputs like battery voltage monitoring in BMS |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial motor control environments |
Pinout & Package
TLV3012AIDBVTG4 is packaged in a 6-pin SOT-23 (DBV) case measuring 2.90 mm × 1.60 mm, optimized for high-density PCB layouts in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Comparator output | Push-pull active driver - eliminates need for external pull-up; sinks/sourses 5 mA directly to 1.8 V/3.3 V logic |
| V− | Negative supply | Ground or negative rail reference - supports single-supply operation down to 1.65 V total supply |
| IN+ | Non-inverting input | Differential sensing node - accepts signals 200 mV below V−, enabling true ground-referenced measurements |
| IN− | Inverting input | Threshold comparison node - compatible with reference output (REF) or external voltage divider |
| REF | Reference output | Stable 1.242 V source - supplies precision bias to IN− or external circuitry; load-regulated to ±1 mV/mA |
| V+ | Positive supply | Highest potential rail - sets upper bound of input common-mode and output swing range |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.242 V reference | ±0.25% initial accuracy and 40–100 ppm/°C drift - replaces discrete Zener/reference ICs in compact BMS designs |
| Fail-safe inputs | Guaranteed defined output state during power ramp-up or floating inputs - prevents spurious MCU wake-up in toll tags |
| Power-on-reset (POR) | Internal reset pulse holds output stable until reference settles - eliminates external POR circuitry in battery-powered clusters |
| Built-in hysteresis | 2–8 mV programmable via supply voltage and temperature - removes need for external positive feedback resistors |
| Rail-to-rail input with 200 mV beyond rails | Supports direct connection to transducer outputs or shunt-based current sense amps without level-shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012BIDBVR | Same functional spec, tape-and-reel packaging (3000 pcs), no G4 suffix - RoHS-compliant but not automotive-grade marking | No AEC-Q200 qualification; suitable for commercial portable devices but not under-hood automotive | Select TLV3012BIDBVR for cost-sensitive consumer designs where automotive qualification is unnecessary |
| MAX9062ASA+ | Higher quiescent current (12 μA), no integrated reference, requires external 1.25 V source; faster 150 ns propagation | Used where speed outweighs power; lacks reference integration - increases BOM count and layout area | Choose MAX9062ASA+ only when >100× speed improvement justifies 4× higher IQ and added reference component |
Compared with TLV3012BIDBVR and MAX9062ASA+, TLV3012AIDBVTG4 uniquely combines automotive-grade qualification (G4 suffix), integrated ±0.25% reference, and 3.1 μA IQ in SOT-23 - making it optimal for space- and power-constrained safety-critical sensing nodes.

FAQ
What is the reference voltage accuracy of TLV3012AIDBVTG4 over temperature?
The TLV3012AIDBVTG4 reference voltage has ±0.25% initial accuracy at 25°C and maintains ±1.5% total accuracy over –40°C to +125°C, with 40–100 ppm/°C temperature drift. This is specified in Section 6.9 of the SBOS300C datasheet and verified across production lots - ensuring consistent trip-point stability in automotive battery monitoring circuits using TLV3012AIDBVTG4.
Does TLV3012AIDBVTG4 require external hysteresis components?
No, TLV3012AIDBVTG4 includes built-in hysteresis of 2–8 mV, which is factory-trimmed and temperature-compensated. This eliminates external feedback resistors in applications like toll tag wake-up detection, where noise immunity is critical. The hysteresis value scales with supply voltage and remains effective across the full –40°C to +125°C range per Figure 8-21 in the TLV3012AIDBVTG4 datasheet.
Can TLV3012AIDBVTG4 operate from a 1.65 V supply?
Yes, TLV3012AIDBVTG4 is fully specified to operate from 1.65 V to 5.5 V supply, unlike the non-"B" version which requires minimum 1.8 V. At 1.65 V, it delivers 3.6 μA max quiescent current over temperature and maintains 4 μs max propagation delay - enabling use with single alkaline or lithium primary cells in asset tracking devices using TLV3012AIDBVTG4.
What is the purpose of the REF pin on TLV3012AIDBVTG4?
REF is a buffered 1.242 V output that can source or sink up to 0.5 mA while maintaining ±1 mV/mA load regulation. It serves as a precision threshold source for IN− or external circuitry - eliminating external voltage dividers in battery voltage monitors. The REF pin is internally decoupled and stable with up to 10 nF capacitive load, as confirmed in Section 3 of the TLV3012AIDBVTG4 datasheet.
Is TLV3012AIDBVTG4 pin-compatible with other comparators in the TLV301x family?
Yes, TLV3012AIDBVTG4 shares identical SOT-23-6 pinout with TLV3011AIDBVT, TLV3012BIDBVR, and TLV3011BIDBVT - all follow the OUT/V−/IN+/IN−/REF/V+ assignment shown in Figure 5-1. However, functional differences exist: TLV3012AIDBVTG4 provides push-pull output and "B"-version features (POR, hysteresis), whereas TLV3011 variants have open-drain outputs and lack those enhancements.
