Product details
Overview
TLV3012BQDCKRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive push-pull output comparator with integrated 1.242V voltage reference, 3.1μA maximum quiescent current, 2µs typical propagation delay, and fail-safe inputs enabling operation with V+ unpowered. It supports 1.65V to 5.5V supply and is used in battery management systems for precise low-power voltage threshold detection.
For engineers reviewing the TLV3012BQDCKRQ1 datasheet, TLV3012BQDCKRQ1 pinout, TLV3012BQDCKRQ1 application, or TLV3012BQDCKRQ1 equivalent, key selection criteria include its automotive-grade reliability, integrated reference accuracy (±1.5%), built-in 6mV hysteresis, power-on-reset timing (1.9ms), and SC-70-6 package footprint compatibility with space-constrained vehicle electronics.
Technical Context
The TLV3012BQDCKRQ1 implements a rail-to-rail input comparator core with push-pull output stage capable of sourcing and sinking up to 0.5mA, eliminating external pull-up resistors. Its integrated 1.242V series reference provides stable output with ≤100ppm/°C drift and supports up to 10nF capacitive load.
Fail-safe inputs tolerate 0V to 5.5V independent of V+, resolving power sequencing issues during cold-cranking or wake-up events. Power-on-reset asserts low output for 1.9ms during V+ ramp-up, ensuring deterministic startup before reference stabilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - enables direct connection to Li-ion single-cell or automotive 3.3V/5V rails without regulation |
| Quiescent Current | 3.1μA max - extends battery life in always-on vehicle subsystems like toll tags or asset trackers |
| Reference Voltage | 1.242V ±1.5% - provides accurate, temperature-stable threshold for precision overvoltage/undervoltage detection |
| Propagation Delay | 2µs to 4µs (typ) - ensures rapid fault response in safety-critical BMS monitoring loops |
| Input Common-Mode Range | V– – 0.2V to V+ + 0.2V - supports sensing beyond supply rails for wide-dynamic-range sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012QDBVRQ1 | SOT-23-6 package (2.9mm × 2.8mm); same electrical specs but larger footprint | Better thermal performance (RθJA = 162.5°C/W vs 169.8°C/W) - preferred for high-ambient-temperature locations | Select when board layout allows larger package and thermal margin is prioritized over size |
| LMV331Q1MG/NOPB | No integrated reference; 1.8V–5.5V supply; 25μA IQ; open-drain only | Requires external reference and pull-up; higher current draw limits use in ultra-low-power wake-up circuits | Select when reference is already available elsewhere in system and cost is primary constraint |

FAQ
What is the minimum supply voltage for TLV3012BQDCKRQ1?
The TLV3012BQDCKRQ1 operates down to 1.65V, enabling direct interface with partially discharged Li-ion cells or low-voltage automotive domains. This is a key differentiator from non-"B" versions (1.8V min) and supports extended runtime in battery-powered vehicle modules. The 1.65V threshold is guaranteed across –40°C to +125°C ambient.
Does TLV3012BQDCKRQ1 require an external pull-up resistor?
No, TLV3012BQDCKRQ1 features a push-pull output that actively drives both high and low states, eliminating the need for an external pull-up resistor. This reduces BOM count, saves PCB area, and avoids power loss associated with pull-up current - especially beneficial in always-on automotive circuits where every microamp matters.
How does the power-on-reset (POR) function in TLV3012BQDCKRQ1?
The TLV3012BQDCKRQ1 POR circuit holds the output low for 1.9ms after V+ crosses the 1.65V threshold during power-up, ensuring deterministic behavior before the internal 1.242V reference stabilizes. This prevents spurious fault assertions in battery management systems during cold-start sequences where supply voltage ramps slowly.
What is the accuracy and temperature drift of the integrated reference in TLV3012BQDCKRQ1?
The TLV3012BQDCKRQ1 integrates a 1.242V series reference with ±1.5% initial accuracy and ≤100ppm/°C maximum temperature drift over –40°C to +125°C. This enables precise voltage thresholding without calibration, critical for meeting ISO 26262 ASIL-B functional safety requirements in automotive BMS applications.
Can TLV3012BQDCKRQ1 inputs operate when V+ is unpowered?
Yes, TLV3012BQDCKRQ1 features fail-safe inputs rated for 0V to 5.5V independent of V+ voltage. This allows the device to monitor external signals (e.g., battery voltage) during vehicle sleep mode when main supply is off, supporting wake-up functionality without power sequencing constraints - a requirement for modern low-power automotive ECUs.
