Product details
Overview
TLV7032DSGR from Texas Instruments is a dual-channel, nanopower, rail-to-rail input comparator with push-pull output, operating from 1.6V to 6.5V supply, consuming only 315nA quiescent current per channel, featuring 3µs propagation delay and internal hysteresis - used for precision voltage monitoring in battery-powered gas detectors and motion sensors.
For engineers reviewing the TLV7032DSGR datasheet, TLV7032DSGR pinout, TLV7032DSGR application, or TLV7032DSGR equivalent, this page delivers verified package mapping (WSON-8), confirmed dual-channel push-pull functionality, exact electrical specs at –40°C to 125°C, and validated alternatives for low-power comparator selection.
Technical Context
The TLV7032DSGR implements a rail-to-rail input stage capable of accepting common-mode voltages up to 0.1V beyond VCC and down to VEE, with no phase reversal under overdriven inputs. Its internal hysteresis (3–25mV) ensures noise immunity in slow-moving signal environments.
It integrates a power-on-reset (POR) circuit that holds the output low during power ramp-up until VCC ≥ 1.6V, enabling reliable startup in energy-constrained systems. The push-pull output drives both high and low actively, sourcing/sinking up to 29mA/33mA at 5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 6.5V - supports direct operation from single-cell Li-ion (3.0V), alkaline (1.5V×2), or 5V logic rails without regulation. |
| Quiescent Current / Channel | 315nA - enables multi-year battery life in always-on sensor nodes (e.g., smoke detectors). |
| Propagation Delay | 3µs - provides fast fault response while maintaining nanoPower efficiency. |
| Input Offset Voltage | ±0.1mV (min), ±8mV (max) - ensures accurate threshold detection across temperature (–40°C to 125°C). |
| Hysteresis | 3mV to 25mV - suppresses chatter on noisy or slowly varying inputs like thermistor or potentiometer outputs. |
| Output Type | Push-pull - eliminates need for external pull-up resistors, simplifies interface to MCU GPIO or LED drivers. |
| Common-Mode Range | Rail-to-rail (VEE to VCC + 0.1V) - accepts inputs beyond supply rails, easing design with unbuffered sensor signals. |
Pinout & Package
TLV7032DSGR is packaged in an 8-pin WSON (DSG) with exposed thermal pad (2.00mm × 2.00mm body), optimized for space-constrained PCB layouts and thermal performance (RθJA = 106.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Output, Channel A | Active push-pull output - sinks or sources current directly; compatible with 3.3V/5V logic levels. |
| INA– (Pin 2) | Inverting Input, Channel A | Differential input node with 2pA bias current - minimizes loading on high-impedance sources (e.g., photodiode amps). |
| INA+ (Pin 3) | Noninverting Input, Channel A | Rail-to-rail input - accepts signals from 0V to VCC + 0.1V, enabling direct connection to unbuffered sensors. |
| VCC (Pin 4) | Positive Supply | Main power input - must exceed 1.6V for >200µs before valid output (power-up timing constraint). |
| INB– (Pin 6) | Inverting Input, Channel B | Independent second comparator input - allows dual-threshold detection (e.g., window comparator with external resistors). |
| OUTB (Pin 7) | Output, Channel B | Second push-pull output - electrically isolated from OUTA; supports independent control paths. |
| VEE (Pin 8) | Negative Supply / Ground | Reference node for single-supply operation - tied to system ground in most portable applications. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal on overdrive | Prevents false triggering when input exceeds supply rails - critical for robustness in industrial sensor interfaces. |
| Internal hysteresis | Eliminates need for external positive feedback components, reducing BOM count and layout area in battery-operated designs. |
| Power-on-reset (POR) | Holds OUTA/OUTB low until VCC stabilizes ≥1.6V - prevents spurious MCU wakeups during brown-out conditions. |
| Rail-to-rail input range | Accepts inputs from VEE to VCC + 0.1V - enables direct interfacing with unbuffered analog sensors without level-shifting circuitry. |
| Ultra-low ICC (315nA/channel) | Reduces average current draw in duty-cycled systems - e.g., 1Hz sampling yields <1nA average supply current per channel. |
Applications
| Gas Detector | Motion Detector |
|---|---|
Use Scenario: Detecting toxic gas concentration thresholds using electrochemical sensor output voltage. IC Role / Device Role / Timing Role: Dual comparator monitors upper/lower alarm thresholds; one channel triggers warning, the other initiates shutdown. Use Value: 315nA quiescent current extends battery life to >5 years in maintenance-free portable gas meters. | Use Scenario: Interpreting analog output from PIR sensor amplifier to detect human movement. IC Role / Device Role / Timing Role: Compares filtered PIR signal against adjustable reference; hysteresis prevents false triggers from ambient noise. Use Value: 3µs propagation delay enables sub-10ms response time while consuming negligible power in always-on security nodes. |
| Smoke & Heat Detector | Servo Drive Position Sensor |
Use Scenario: Monitoring thermistor voltage in dual-sensor smoke alarms to distinguish smoldering vs flaming fires. IC Role / Device Role / Timing Role: One comparator detects rapid temperature rise (heat), the other validates smoke chamber opacity (ionization current). Use Value: Rail-to-rail input accepts full thermistor swing (0–5V); internal hysteresis rejects EMI-induced transients near HVAC ducts. | Use Scenario: Converting analog position feedback from potentiometer or resolver into digital direction/state signals for motor control. IC Role / Device Role / Timing Role: Dual comparator implements window comparator to detect in-range, overtravel, or failure states. Use Value: Push-pull outputs drive MCU interrupt pins directly; 125°C rating supports operation inside enclosed servo housings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7042DSGR | Open-drain output instead of push-pull; identical supply range, ICC, and propagation delay. | Requires external pull-up for logic-high output; suited for level translation or wired-OR bus configurations. | Select TLV7042DSGR only when open-drain functionality is required - not a drop-in replacement due to output architecture mismatch. |
| MAX9022AUT+ | Higher ICC (1.1µA/channel), slower tPD (6µs), same 1.8–5.5V supply range; SC70-8 package. | Lacks rail-to-rail input (CMVR = 0.2V to VCC – 0.2V); no internal hysteresis. | Choose MAX9022AUT+ only if higher speed tolerance and external hysteresis design are acceptable - not functionally equivalent. |
Compared with TLV7042DSGR, TLV7032DSGR offers active drive capability eliminating pull-ups, while MAX9022AUT+ trades power and precision for legacy compatibility - TLV7032DSGR remains optimal for new ultra-low-power, rail-to-rail, hysteresis-integrated designs.

FAQ
What is the minimum supply voltage required for reliable operation of TLV7032DSGR?
The TLV7032DSGR requires a minimum supply voltage of 1.6V for normal operation, with a power-on-reset circuit holding outputs low until VCC exceeds this threshold for at least 200µs. Operation below 1.6V is undefined, and the device does not guarantee functionality at 1.2V - unlike TLV7032 variants with "S" or "L" suffixes.
Does TLV7032DSGR support rail-to-rail input voltage range?
Yes, TLV7032DSGR supports a rail-to-rail common-mode input voltage range from VEE to VCC + 0.1V, enabling direct connection to unbuffered sensors or signals that swing beyond the supply rails - a key advantage over comparators with limited input ranges.
Can TLV7032DSGR replace TLV7042DSGR in an existing design?
No, TLV7032DSGR cannot directly replace TLV7042DSGR because it features a push-pull output versus open-drain. Swapping them requires removing external pull-up resistors and verifying load compatibility - TLV7032DSGR drives high actively, whereas TLV7042DSGR relies on external pull-ups for logic-high states.
What is the typical hysteresis value of TLV7032DSGR and how is it implemented?
The TLV7032DSGR includes fixed internal hysteresis ranging from 3mV to 25mV (typical 10mV), implemented via on-chip feedback - no external components needed. This hysteresis is factory-trimmed and temperature-stable, ensuring consistent noise immunity across –40°C to 125°C without design overhead.
Is TLV7032DSGR qualified for automotive applications?
No, TLV7032DSGR is not AEC-Q200 qualified. It operates across –40°C to +125°C, meeting industrial temperature requirements, but lacks automotive-specific qualification, stress testing, or PPAP documentation - use only in industrial, consumer, or medical portable equipment unless re-qualified by the end customer.
