Product details
Overview
TLV7032QDGKRQ1 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 TLV7032QDGKRQ1 datasheet, TLV7032QDGKRQ1 pinout, TLV7032QDGKRQ1 application, or TLV7032QDGKRQ1 equivalent, this page delivers verified functional identity, package mapping (8-pin VSSOP), dual-channel timing behavior, and validated alternatives for low-voltage, ultra-low-power comparator selection in automotive-qualified designs.
Technical Context
The TLV7032QDGKRQ1 implements a rail-to-rail input stage capable of accepting common-mode voltages up to 100mV beyond VCC and down to VEE – 0.1V, with built-in hysteresis (3–25mV) to prevent chatter on slow-moving signals. Its push-pull output drives both high and low actively, sourcing/sinking ≥29mA (sourcing) and ≥33mA (sinking) at 5V.
It integrates a power-on-reset (POR) circuit that holds the output low during power ramp-up until VCC ≥1.6V is sustained for ≥200µs, ensuring deterministic startup. The device supports single-supply operation with VEE referenced to ground and operates across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 6.5V - compatible with 1.8V, 3.3V, and 5V systems; enables direct integration into Li-ion, coin-cell, and industrial supply rails. |
| Quiescent Current / Channel | 315nA - enables multi-year operation on microampere-scale energy budgets in always-on sensor nodes. |
| Propagation Delay | 3µs - provides fast fault detection while maintaining nanoPower efficiency, critical for responsive safety monitoring. |
| Input Offset Voltage | ±0.1mV (min), ±8mV (max) - ensures accurate threshold detection across temperature and supply variations. |
| Common-Mode Input Range | Rail-to-rail (VEE to VCC + 0.1V) - allows direct sensing of signals near supply rails without level-shifting circuitry. |
| Hysteresis | 3mV to 25mV - suppresses noise-induced false triggering in EMI-prone environments like motor-driven motion detectors. |
| Output Type | Push-pull - eliminates need for external pull-up resistors, simplifies interface to MCUs and logic gates. |
Pinout & Package
TLV7032QDGKRQ1 is housed in an 8-pin VSSOP (DGK) package measuring 3.00mm × 3.00mm, with exposed thermal pad connected to VEE for improved thermal performance (RθJA = 211.7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Output, Channel A | Active push-pull output; sinks/sours milliamps directly - interfaces to MCU GPIO or LED driver without external components. |
| INA– (Pin 2) | Inverting Input, Channel A | Differential input node; accepts rail-to-rail common-mode voltage - enables direct connection to resistive divider outputs. |
| INA+ (Pin 3) | Noninverting Input, Channel A | Differential input node; matched bias current (<2pA) minimizes offset error in high-impedance sensor interfaces. |
| VCC (Pin 4) | Positive Supply | Main power rail; must exceed 1.6V for ≥200µs before valid output - POR ensures clean startup in brown-out conditions. |
| INB– (Pin 6) | Inverting Input, Channel B | Independent second comparator input; supports dual-threshold or window-comparator configurations. |
| OUTB (Pin 7) | Output, Channel B | Second push-pull output; electrically isolated from OUTA - enables independent control of two system states. |
| VEE (Pin 8) | Negative Supply / Ground | Reference node for both inputs and outputs; thermal pad must be soldered to PCB ground plane for thermal reliability. |
Key Features

FAQ
What is the operating temperature range of TLV7032QDGKRQ1?
TLV7032QDGKRQ1 is qualified for operation from –40°C to +125°C and meets AEC-Q100 Grade 1 requirements. This range is validated across all electrical parameters including input offset voltage, propagation delay, and supply current - enabling deployment in under-hood automotive modules and industrial environments with wide ambient swings.
Does TLV7032QDGKRQ1 include internal hysteresis?
Yes, TLV7032QDGKRQ1 includes factory-trimmed internal hysteresis ranging from 3mV to 25mV depending on supply voltage and temperature. This hysteresis is implemented on-chip and requires no external components - providing noise immunity for slow-moving signals in gas meters and motion detectors without design overhead.
What is the output configuration of TLV7032QDGKRQ1?
TLV7032QDGKRQ1 features a push-pull output stage on both channels (OUTA and OUTB). Each output can actively drive high (to VCC) and low (to VEE) without external pull-up resistors - simplifying interface to microcontrollers, FPGAs, and logic families while minimizing standby current in battery-powered applications.
Can TLV7032QDGKRQ1 operate from a 1.8V supply?
Yes, TLV7032QDGKRQ1 operates reliably from 1.8V supply (within its 1.6V–6.5V range). At 1.8V, it maintains 315nA typical supply current per channel and 3µs propagation delay - making it ideal for single-cell Li-ion or NiMH-powered portable equipment where low-voltage operation is essential.
Is TLV7032QDGKRQ1 pin-compatible with other TLV703x devices?
TLV7032QDGKRQ1 in the DGK (VSSOP-8) package shares identical pinout with TLV7032DR and TLV7042DGKR - but TLV7042 has open-drain outputs and different output behavior. Pin compatibility is confirmed only within the same package variant (DGK); cross-package substitution (e.g., WSON or SOT-23-8) requires layout revision due to differing pin assignments and thermal pad requirements.
