Product details
Overview
TLV3012AIDCKT from Texas Instruments is a push-pull output, low-power comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (B-version), 2–4 μs propagation delay, and rail-to-rail input common-mode range extending 200 mV beyond supply rails. It operates from 1.65 V to 5.5 V and is used in battery management systems for precise voltage threshold detection.
For engineers reviewing the TLV3012AIDCKT datasheet, TLV3012AIDCKT pinout, TLV3012AIDCKT application, or TLV3012AIDCKT equivalent, key selection factors include its integrated reference accuracy (±0.25% initial), built-in hysteresis (2–8 mV), fail-safe inputs, power-on-reset functionality, and SC-70-6 package suitability for space-constrained portable electronics.
Technical Context
The TLV3012AIDCKT implements a precision comparator core with an on-chip series voltage reference buffered to drive up to 0.5 mA load. Its push-pull output stage eliminates external pull-up requirements and supports direct interfacing with digital logic or microcontroller GPIOs.
It features internal hysteresis (2–8 mV, temperature-dependent), fail-safe input protection that prevents erroneous outputs during power ramp-up, and a dedicated power-on-reset circuit ensuring known output state at startup - all enabled without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables operation directly from single-cell Li-ion (3.0–4.2 V) or coin-cell (1.8–3.0 V) sources without regulation. |
| Quiescent Current | 3.1 μA max at 25°C - supports multi-year battery life in always-on monitoring applications like asset tracking. |
| Reference Voltage | 1.242 V ±0.25% - provides stable, factory-trimmed threshold for accurate overvoltage/undervoltage detection without external resistors. |
| Propagation Delay | 2–4 μs (low-to-high & high-to-low) - ensures timely response to fast transients in safety-critical BMS fault signaling. |
| Input Common-Mode Range | (V−) − 0.2 V to (V+) + 0.2 V - allows direct sensing of signals below ground or above supply, e.g., battery cell voltage monitoring. |
| Hysteresis | 2–8 mV - suppresses chatter near switching thresholds in noisy environments such as automotive or industrial sensor interfaces. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-range portable equipment. |
Pinout & Package
TLV3012AIDCKT is packaged in a 6-pin SC-70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for ultra-compact PCB layouts in wearables and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Comparator output | Push-pull active-high/active-low output - drives logic inputs directly; no external pull-up required. |
| V− | Negative supply | Ground or negative rail connection; reference for all input/output voltage specifications. |
| IN+ | Non-inverting input | Accepts signal up to (V−) − 0.2 V or (V+) + 0.2 V - enables true rail-to-rail+ sensing. |
| IN− | Inverting input | Same extended common-mode range as IN+; supports differential or single-ended configurations. |
| REF | Reference output | Stable 1.242 V source - powers external circuits or sets comparator thresholds; load-regulated to ≤1 mV/mA. |
| V+ | Positive supply | Primary power connection; supplies both comparator core and reference circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.242 V reference | Eliminates external reference IC or resistor divider, reducing BOM count and layout area while improving long-term stability (≤100 ppm/°C drift). |
| Fail-safe inputs | Prevents undefined output states during power-up or brownout - critical for reliable system initialization in automotive and industrial controllers. |
| Power-on-reset (POR) | Guarantees known output state (low for TLV3012x) within 1.9 ms of V+ reaching valid level - avoids spurious wakeups or false alarms. |
| Built-in hysteresis | 2–8 mV internal hysteresis reduces need for external positive feedback networks, simplifying design and improving noise immunity in EMI-prone environments. |
| SC-70-6 package | 2.00 mm × 1.25 mm footprint saves >35% board area vs. SOT-23-6 - ideal for miniaturized battery-powered devices like toll tags and medical sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012DBVR | SOT-23-6 package (2.90 mm × 1.60 mm); identical electrical specs and pinout. | Less board-area-constrained designs where thermal performance (RθJA = 162.5°C/W) or hand-solderability is prioritized. | Select TLV3012DBVR for prototyping or higher-power-density layouts where SC-70 reflow yield is a concern. |
| TLV3012BIDCKR | Same SC-70-6 package and B-version features; tape-and-reel packaging (3000 pcs/reel vs. 250 pcs for TLV3012AIDCKT). | High-volume production requiring automated pick-and-place compatibility and lower unit cost. | Choose TLV3012BIDCKR for volume manufacturing; note identical functionality and qualification - only packaging differs. |
Compared with TLV3012DBVR and TLV3012BIDCKR, TLV3012AIDCKT offers the same precision reference, hysteresis, and fail-safe operation in a smaller SC-70 footprint with sample-friendly 250-piece reel - making it optimal for evaluation, low-volume production, and space-limited designs where thermal margin is sufficient.

FAQ
What is the reference voltage accuracy of TLV3012AIDCKT?
The TLV3012AIDCKT features a factory-trimmed 1.242 V series voltage reference with ±0.25% initial accuracy over temperature (−40°C to +125°C), as specified in Section 6.9 of the SBOS300C datasheet. This accuracy enables precise threshold setting without external calibration, supporting reliable voltage monitoring in battery management and safety-critical systems.
Does TLV3012AIDCKT require external hysteresis components?
No, TLV3012AIDCKT includes built-in hysteresis of 2–8 mV (typical), eliminating the need for external positive feedback resistors. This internal hysteresis is inherent to the B-version architecture and improves noise immunity in applications like toll tag signal detection or industrial sensor interfaces where EMI may cause false triggering.
What is the minimum supply voltage for TLV3012AIDCKT?
The TLV3012AIDCKT operates down to 1.65 V, as confirmed in Section 6.6 (Recommended Operating Conditions) and Section 6.9 (Electrical Characteristics) of the SBOS300C datasheet. This allows direct interface with low-voltage energy sources such as single alkaline cells (1.5 V nominal) or aging lithium coin cells, extending usable battery life in portable electronics.
How does the power-on-reset (POR) function in TLV3012AIDCKT?
The TLV3012AIDCKT incorporates an internal POR circuit that holds the output low until the supply voltage (V+) reaches a valid level and stabilizes, completing within 1.9 ms. This ensures deterministic startup behavior in systems like automotive clusters or medical sensors, preventing undefined logic states during power ramp-up and eliminating need for external reset supervisors.
Is TLV3012AIDCKT pin-compatible with other devices in the TLV301x family?
Yes, TLV3012AIDCKT shares identical pinout and SC-70-6 footprint with TLV3011AIDCKT, TLV3011BIDCKT, and TLV3012BIDCKT. All variants use Pin 1 (OUT), Pin 2 (V−), Pin 3 (IN+), Pin 4 (IN−), Pin 5 (REF), and Pin 6 (V+). However, functional differences exist - e.g., TLV3011x has open-drain output, while TLV3012x uses push-pull - so electrical interface must be verified per application.
