Product details
Overview
TLV7032DGKR 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 TLV7032DGKR datasheet, TLV7032DGKR pinout, TLV7032DGKR application, or TLV7032DGKR equivalent, this page delivers verified package mapping (VSSOP-8), confirmed dual-channel push-pull functionality, exact input offset (±0.1mV min), rail-to-rail common-mode range, and real-world design implications for low-power fault detection circuits.
Technical Context
The TLV7032DGKR implements a CMOS input stage enabling rail-to-rail common-mode operation up to VCC + 0.1V and down to VEE – 0.1V, with input bias current of 2pA and input offset current of 1pA. Its internal hysteresis (3–25mV) suppresses noise-induced output oscillation during slow-moving signal transitions.
It integrates a power-on-reset (POR) circuit that holds the output low at VEE until VCC exceeds 1.6V, ensuring defined startup behavior. The push-pull output drives loads up to 3mA with VOH ≥ 4.65V and VOL ≤ 350mV at 5V supply, eliminating external pull-up requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 6.5V - supports direct interface with 1.8V, 3.3V, and 5V logic and sensor rails without level shifting. |
| Quiescent Current / Channel | 315nA - enables multi-year operation on coin-cell batteries in always-on monitoring systems. |
| Propagation Delay | 3µs - provides fast fault response while maintaining nanoPower efficiency for battery-critical applications. |
| Input Offset Voltage | ±0.1mV (min) - ensures high-accuracy threshold detection in precision sensor interfaces like gas metering. |
| Common-Mode Input Range | Rail-to-rail (VEE to VCC + 0.1V) - allows direct sensing of signals near supply rails, e.g., battery voltage monitoring down to 0V ground reference. |
| Output Type | Push-pull - eliminates need for external pull-up resistors, simplifies PCB layout, and enables direct LED driving or capacitive load switching. |
| Hysteresis | 3–25mV - prevents chatter on noisy inputs (e.g., smoke detector analog outputs), reducing false triggers without external components. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00mm × 3.00mm body, 0.65mm pitch, exposed thermal pad connected to VEE for improved thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Output, Channel A | Push-pull digital output capable of sourcing/sinking 3mA - directly drives logic inputs or small LEDs. |
| 2 (INA–) | Inverting Input, Channel A | Differential input node with 2pA bias current - minimizes loading on high-impedance sensor sources. |
| 3 (INA+) | Noninverting Input, Channel A | High-impedance input accepting rail-to-rail common-mode signals - enables direct connection to resistive divider outputs. |
| 4 (VEE) | Negative Supply / Ground | Reference node for single-supply operation; thermal pad must be soldered to PCB ground plane for thermal stability. |
| 5 (INB–) | Inverting Input, Channel B | Independent second comparator input - supports dual-threshold detection (e.g., over/under-voltage window). |
| 6 (OUTB) | Output, Channel B | Independent push-pull output - enables concurrent monitoring of two separate analog signals. |
| 7 (INB+) | Noninverting Input, Channel B | Second high-Z input with same rail-to-rail capability - allows differential or independent single-ended sensing paths. |
| 8 (VCC) | Positive Supply | Primary power rail; POR circuit activates below 1.6V, holding both outputs low until stable supply is established. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Accepts input voltages from VEE – 0.1V to VCC + 0.1V - enables direct monitoring of battery voltage, sensor bridges, or DAC outputs without clamping diodes. |
| Internal hysteresis | 3–25mV programmable via supply voltage - eliminates need for external positive feedback resistors in noisy industrial environments. |
| No phase reversal on overdrive | Maintains correct output polarity even when inputs exceed common-mode range - critical for reliable fault signaling in safety-critical detectors. |
| Power-on-reset (POR) | Holds outputs low until VCC ≥ 1.6V - prevents undefined logic states during power ramp-up in portable medical or security devices. |
| Ultra-low ICC (315nA/ch) | Enables continuous operation on CR2032 coin cells for >10 years in standby - validated across –40°C to 125°C ambient range. |

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 |
|---|---|---|---|
| TLV7042DGKR | Open-drain output instead of push-pull; identical supply range, current, and delay. | Requires external pull-up for logic-level output; suited for wired-OR bus or level translation. | Select TLV7042DGKR only when open-drain functionality is required - not a drop-in replacement for push-pull load driving. |
| MAX9022AUT+ | Higher quiescent current (1.1µA/ch), no internal hysteresis, SOT-23-8 package. | Lacks integrated hysteresis and rail-to-rail input - requires external components for noise immunity and full-range sensing. | Choose MAX9022AUT+ only if higher speed (1.5µs) outweighs 3.5× higher ICC and added external component cost. |
Compared with TLV7042DGKR and MAX9022AUT+, the TLV7032DGKR uniquely delivers push-pull drive, internal hysteresis, and rail-to-rail input in a space-optimized VSSOP-8 package - making it optimal for self-contained, ultra-low-power dual-threshold detection where board area and component count are constrained.

FAQ
What is the minimum operating supply voltage for TLV7032DGKR?
The TLV7032DGKR operates down to 1.6V supply voltage under recommended conditions. While the "S" and "L" variants of the TLV703x family support 1.2V minimum, the TLV7032DGKR (standard dual variant) is specified from 1.6V to 6.5V. Operation below 1.6V activates the power-on-reset circuit, holding both outputs low until VCC stabilizes above threshold.
Does TLV7032DGKR include internal hysteresis, and how does it affect design?
Yes, TLV7032DGKR includes factory-trimmed internal hysteresis ranging from 3mV to 25mV depending on supply voltage and temperature. This eliminates the need for external positive feedback resistors in most noise-prone applications - such as gas detector analog front-ends - simplifying layout and improving reliability without sacrificing threshold accuracy.
Can TLV7032DGKR drive an LED directly?
Yes, TLV7032DGKR can drive a standard indicator LED directly via its push-pull output. At 5V supply, it sources up to 29mA and sinks up to 33mA, supporting typical 2–20mA LED currents. For a 5mm red LED (2.1V forward voltage, 10mA target), a 270Ω series resistor suffices - no external transistor or driver IC is needed.
What is the purpose of the exposed thermal pad on TLV7032DGKR's VSSOP-8 package?
The exposed thermal pad on TLV7032DGKR (DGK package) must be soldered to a PCB copper pour connected to VEE (ground). It reduces junction-to-board thermal resistance to 133.5°C/W, preventing thermal shutdown during sustained output loading and improving long-term reliability in sealed enclosures like smoke detectors.
How does TLV7032DGKR handle input overdrive beyond the supply rails?
TLV7032DGKR features no phase reversal under overdrive: even when IN+ or IN– exceeds VCC or falls below VEE by up to 0.3V, the output maintains correct logical polarity. This behavior - confirmed in TI's characterization data - ensures reliable fault signaling in systems where transient overvoltage events occur, such as ESD-coupled sensor lines in industrial motion detectors.
