Product details
Overview
TLV9032DGKR from Texas Instruments is a dual-channel, precision rail-to-rail input comparator with push-pull output, 300 µV max input offset voltage, 100 ns typical propagation delay, and 16 µA per-channel quiescent current across 1.65 V to 5.5 V supply. It operates from –40°C to +125°C and is used for overvoltage detection in motor drive control circuits.
For engineers reviewing the TLV9032DGKR datasheet, TLV9032DGKR pinout, TLV9032DGKR application, or TLV9032DGKR equivalent, key selection criteria include push-pull drive capability for direct LED/MOSFET gate interfacing, fault-tolerant inputs (–0.3 V to 6 V), low-power operation in battery-sensitive industrial sensors, and guaranteed performance over full temperature range.
Technical Context
The TLV9032DGKR implements a high-speed, low-power comparator core with internal biasing optimized for stable operation at 1.65 V minimum supply. Its rail-to-rail input stage supports common-mode voltages extending 0.2 V beyond both rails, while the push-pull output delivers ±4 mA sourcing/sinking capability without external pull-up.
Designed for harsh environments, it integrates ESD protection (2 kV HBM), input fault tolerance up to 6 V independent of supply, and robust PSRR (75–95 dB) across 1.8 V–5.5 V operation - enabling reliable voltage monitoring in noisy factory automation and motor control systems.
Key Specifications

Applications
| Overvoltage Protection in Motor Drives | Power Supply Sequencing in PLCs |
|---|---|
Use Scenario: Monitors DC bus voltage in BLDC motor inverters to trigger immediate shutdown if >45 V. IC Role / Device Role / Timing Role: Dual comparator compares sensed bus voltage against two independent thresholds: one for warning (42 V), one for hard cutoff (45 V). Use Value: Push-pull outputs drive FPGA interrupt pins directly; 100 ns delay ensures sub-microsecond fault response before IGBT damage occurs. | Use Scenario: Ensures correct power-up order of 5 V, 3.3 V, and 1.8 V rails in programmable logic controller mainboards. IC Role / Device Role / Timing Role: Each comparator monitors one rail against its reference; OUT1 and OUT2 feed AND-gate logic to enable downstream regulators only when all are valid. Use Value: 16 µA/channel quiescent current minimizes standby loss; rail-to-rail inputs allow direct connection to each rail without attenuation. |
| Temperature-Compensated Battery Monitoring | LED Status Indication in Building Automation |
Use Scenario: Detects end-of-charge and over-discharge conditions in 12 V lead-acid backup batteries used in HVAC controllers. IC Role / Device Role / Timing Role: One channel compares battery voltage to fixed 14.4 V upper threshold; second channel compares against temperature-compensated lower threshold derived from NTC network. Use Value: ±0.3 mV offset ensures <10 mV total error in 14 V range; fault-tolerant inputs survive load-dump transients up to 6 V above nominal. | Use Scenario: Drives red/green status LEDs on smart lighting control panels based on occupancy sensor output and dimming command validity. IC Role / Device Role / Timing Role: TLV9032DGKR channels compare analog sensor output and PWM duty cycle against fixed thresholds to assert LED ON/OFF states. Use Value: Push-pull outputs source 4 mA to drive LEDs directly; no external drivers or resistors needed - reduces BOM count and board space. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV393IDR | Higher 40 µA/channel quiescent current; 300 ns propagation delay; open-drain only output. | Requires external pull-up for logic-level output; less suitable for direct MOSFET gate driving. | Select when cost sensitivity outweighs speed/power needs and open-drain interface is acceptable. |
| TLV7032DR | Lower 1.5 V min supply; 150 ns propagation delay; same push-pull output and 300 µV offset. | Better for ultra-low-voltage systems (e.g., coin-cell IoT sensors); slightly slower response limits use in fast fault detection. | Select when operating below 1.65 V is required and 50 ns additional delay is tolerable. |
Compared with LMV393IDR and TLV7032DR, the TLV9032DGKR delivers optimal balance of speed (100 ns), ultra-low power (16 µA), and push-pull drive strength - making it preferred for industrial motor control and PLC sequencing where timing, efficiency, and interface simplicity are jointly critical.

FAQ
What is the maximum input voltage the TLV9032DGKR can tolerate without damage?
The TLV9032DGKR features fault-tolerant inputs rated from –0.3 V to 6 V relative to V–, independent of supply voltage. This allows safe operation during load dump events or mismatched supply sequencing in industrial systems - no external clamping diodes are required as long as input current remains ≤10 mA.
Does the TLV9032DGKR support rail-to-rail input common-mode range?
Yes, the TLV9032DGKR supports a common-mode input voltage range from (V–) – 0.2 V to (V+) + 0.2 V across its full operating temperature range. This enables direct sensing of supply rails, battery terminals, or sensor outputs without level-shifting circuitry - critical for compact, high-accuracy monitoring designs.
Can the TLV9032DGKR drive a MOSFET gate directly?
Yes, the TLV9032DGKR's push-pull output can source and sink ≥4 mA, enabling direct drive of small-signal MOSFET gates (e.g., 2N7002, DMN2004) without external buffers. Its 100 ns propagation delay and low output impedance ensure fast switching - ideal for overcurrent protection circuits in motor drives.
What is the typical quiescent current per channel of the TLV9032DGKR at 1.8 V supply?
The TLV9032DGKR draws 16 µA per channel at 1.8 V supply and 25°C, rising to ≤35 µA across –40°C to +125°C. This ultra-low current enables always-on voltage supervision in battery-backed systems such as smart thermostats and remote I/O modules without compromising runtime.
Is the TLV9032DGKR pin-compatible with other devices in the TLV90xx family?
No - the TLV9032DGKR (DGK/VSSOP-8) has a unique pinout distinct from SOIC-8 (D), TSSOP-8 (PW), and WSON-8 (DSG) variants. While functional compatibility exists across the TLV903x dual push-pull series, PCB layout must match the DGK package's 3.00 mm × 3.00 mm footprint and exposed thermal pad connection to V–.
