Product details
Overview
TLV7012DSGR from Texas Instruments is a dual-channel, micropower voltage comparator with push-pull outputs, rail-to-rail input capability (VEE to VCC + 0.1 V), 5 µA quiescent supply current per channel, and 260 ns typical propagation delay (tPLH) at 5 V supply. It operates from 1.6 V to 6.5 V and is used in battery-powered threshold detection and level translation circuits.
For engineers reviewing the TLV7012DSGR datasheet, TLV7012DSGR pinout, TLV7012DSGR application, or TLV7012DSGR equivalent, key selection criteria include its dual-channel push-pull output architecture, ultra-low power consumption across wide temperature range (–40°C to 125°C), internal hysteresis for noise immunity, and compatibility with space-constrained portable designs using the 8-pin WSON package.
Technical Context
The TLV7012DSGR implements two independent high-precision comparators with rail-to-rail inputs capable of accepting signals up to 100 mV beyond VCC, and no phase reversal under overdriven conditions. Its internal hysteresis (2–15 mV typ.) enhances noise rejection in low-slew-rate signal environments.
Each channel features a push-pull output stage capable of sourcing/sinking ≥3 mA at 5 V, enabling direct LED driving or capacitive load switching without external pull-up. The device integrates a Power-on-Reset (POR) circuit that holds outputs low during supply ramp-up until VCC ≥ 1.6 V for ≥20 µs.

Pinout & Package
TLV7012DSGR is packaged in an 8-pin WSON (DSG) with exposed thermal pad (2 mm × 2 mm body size, 0.75 mm height). The thermal pad must be connected to VEE (ground) for optimal thermal performance and ESD robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Output A | Push-pull digital output; actively drives high/low without external pull-up; sinks ≥33 mA, sources ≥29 mA at 5 V. |
| INA– (Pin 2) | Inverting Input A | Differential input node for channel A; rail-to-rail capable (VEE to VCC + 0.1 V); fault-tolerant to 5.5 V. |
| INA+ (Pin 3) | Noninverting Input A | Differential input node for channel A; identical electrical characteristics and fault tolerance as INA–. |
| VEE (Pin 4) | Negative Supply / Ground | Reference return for both channels and thermal pad connection point; required for proper POR and output logic. |
| INB+ (Pin 5) | Noninverting Input B | Differential input node for channel B; electrically isolated from channel A; shares same input specs and tolerance. |
| INB– (Pin 6) | Inverting Input B | Differential input node for channel B; fully independent; supports separate thresholds per channel. |
| OUTB (Pin 7) | Output B | Push-pull digital output for channel B; identical drive strength and timing to OUTA; no cross-talk with OUTA. |
| VCC (Pin 8) | Positive Supply | Main power input (1.6–6.5 V); powers both comparators and internal POR; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with overvoltage tolerance | Accepts inputs from VEE to VCC + 0.1 V; survives up to 5.5 V regardless of VCC state - simplifies sensor interface design. |
| Internal hysteresis | 2–15 mV programmable via external resistor network - eliminates need for discrete hysteresis components in threshold detectors. |
| No phase inversion on overdrive | Output remains logically consistent even when inputs exceed supply rails - prevents false triggering in transient conditions. |
| Power-on-reset (POR) circuit | Holds both outputs low until VCC ≥ 1.6 V and stable for ≥20 µs - ensures known startup state in battery-powered systems. |
| Ultra-small WSON package | 2 mm × 2 mm footprint with thermal pad - reduces PCB area by >50% vs. SOT-23-8 while improving thermal dissipation. |
Applications
| Battery Voltage Monitor | IR Receiver Front End |
|---|---|
|
Use Scenario: Monitoring lithium-ion cell voltage during charging/discharging to trigger low-battery alerts or cutoff. IC Role / Device Role / Timing Role: Dual comparator performs simultaneous high-threshold (overvoltage) and low-threshold (undervoltage) detection with independent hysteresis. Use Value: 5 µA total quiescent current extends shelf life of sealed battery packs; rail-to-rail inputs directly sense 0–4.2 V cell range without resistive dividers. |
Use Scenario: Converting weak, noisy IR photodiode signals into clean digital pulses for microcontroller decoding. IC Role / Device Role / Timing Role: One channel detects carrier envelope (peak-hold comparison), the other discriminates data pulses against adaptive threshold. Use Value: 260 ns propagation delay enables reliable 38 kHz carrier detection; internal hysteresis rejects ambient light interference without external RC networks. |
| Portable Level Translator | Window Comparator for Sensor Fault Detection |
|
Use Scenario: Translating 1.8 V logic outputs from an MCU to 5 V-compatible peripherals in handheld test equipment. IC Role / Device Role / Timing Role: Push-pull outputs drive 5 V loads directly; dual channels support bidirectional level shift (e.g., I²C SDA/SCL). Use Value: Eliminates external MOSFETs or dedicated level translators; 1.6 V minimum supply allows operation from partially discharged batteries. |
Use Scenario: Validating thermistor or RTD output stays within safe operational bounds in medical wearable devices. IC Role / Device Role / Timing Role: Configured as window comparator: one channel triggers upper limit, the other lower limit; OR'd output flags out-of-range condition. Use Value: Internal hysteresis prevents oscillation near trip points; –40°C to 125°C rating ensures reliability across patient-body and environmental temperature swings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7022DSGR | Open-drain outputs instead of push-pull; identical supply range, quiescent current, and propagation delay. | Requires external pull-up for logic-high output; suited for wired-OR bus interfaces or bipolar-to-single-ended conversion. | Select TLV7022DSGR only when level translation beyond VCC or bus arbitration is required; otherwise TLV7012DSGR offers simpler drive capability. |
| LMV7235MFX/NOPB | Higher quiescent current (55 µA), faster propagation (4.5 ns), but narrower supply range (2.7–5.5 V) and no internal hysteresis. | Used in high-speed precision applications where speed outweighs power budget; requires external hysteresis resistors. | Choose LMV7235MFX/NOPB for <10 ns response-critical systems; TLV7012DSGR is superior for micropower, wide-VCC, and integrated-hysteresis needs. |
Compared with TLV7022DSGR and LMV7235MFX/NOPB, the TLV7012DSGR uniquely balances ultra-low power (5 µA), rail-to-rail input flexibility, built-in hysteresis, and push-pull drive - making it optimal for space- and energy-constrained portable electronics requiring robust, self-contained threshold detection.

FAQ
What is the maximum input voltage the TLV7012DSGR can tolerate on its IN+ and IN– pins?
The TLV7012DSGR inputs are fault-tolerant up to 5.5 V regardless of VCC level, and operate within a common-mode range of VEE to VCC + 0.1 V. This allows direct connection to sensors or signals exceeding the supply rail - for example, a 5 V sensor output can safely interface with TLV7012DSGR powered from 3.3 V, provided current into the pins is limited to ≤10 mA per input.
Does the TLV7012DSGR require external hysteresis resistors?
No, the TLV7012DSGR includes internal hysteresis (2–15 mV typ.) that is fixed and non-adjustable. This eliminates the need for external feedback resistors in most threshold-detection applications. For applications requiring precise or variable hysteresis, external resistors may be added - but doing so overrides the internal hysteresis and must be validated per the datasheet's hysteresis calculation guidelines.
Can the TLV7012DSGR operate from a single 1.8 V supply?
Yes, the TLV7012DSGR is fully specified for operation from 1.6 V to 6.5 V. At 1.8 V, it maintains 5 µA typical quiescent current per channel, 260 ns propagation delay, and rail-to-rail input operation from 0 V to 1.9 V. This makes TLV7012DSGR ideal for ultra-low-voltage systems like energy-harvesting sensors and NFC-enabled tags.
How does the Power-on-Reset (POR) function behave on the TLV7012DSGR?
The TLV7012DSGR's POR circuit asserts during VCC ramp-up or ramp-down, holding both OUTA and OUTB low (at VEE) until VCC reaches ≥1.6 V and remains stable for ≥20 µs. This guarantees a known, safe output state at power-on - critical for preventing spurious actuation in motor drivers, relays, or LED indicators controlled by TLV7012DSGR outputs.
Is the thermal pad on the TLV7012DSGR (DSG package) electrically connected?
Yes, the exposed thermal pad on the TLV7012DSGR's WSON package is internally connected to VEE (pin 4). It must be soldered to a PCB copper pour tied to the system ground plane to ensure proper thermal dissipation, ESD protection, and electrical stability. Leaving the pad floating or connecting it to another net violates the device's thermal and reliability specifications.
