Product details
Overview
V62/23603-01XE from Texas Instruments is a radiation-hardened, enhanced-product push-pull output comparator with integrated 1.242-V voltage reference, 3.1 μA maximum quiescent current, –55°C to 125°C operating temperature range, and 2 μs typical propagation delay. It serves as a precision voltage detection element in battery-powered monitoring and fault-response circuits.
For engineers reviewing the V62/23603-01XE datasheet, V62/23603-01XE pinout, V62/23603-01XE application, or V62/23603-01XE equivalent, this page delivers verified electrical specs, SOT-23-6 terminal mapping, hysteresis-enabled threshold detection capability, fail-safe input behavior, and power-on reset functionality - all validated for high-reliability aerospace and defense systems.
Technical Context
The V62/23603-01XE implements a rail-to-rail input comparator core with push-pull output stage and an internally trimmed series voltage reference. Its integrated hysteresis (2–8 mV) eliminates oscillation near threshold crossings without external components.
It features fail-safe inputs that remain functional even when input voltages exceed supply rails by up to 200 mV, and includes a dedicated power-on reset circuit ensuring deterministic output state during power ramp-up. The reference output supports ±0.5 mA sourcing/sinking with ≤100 ppm/°C drift over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.65 V to 5.5 V - enables direct interface with low-voltage microcontrollers and legacy 5-V logic without level-shifting. |
| Quiescent Current | 3.1 μA max - allows multi-year operation on coin-cell batteries in remote sensor nodes. |
| Reference Voltage | 1.242 V ±0.25% initial accuracy - provides stable, factory-trimmed threshold for precision undervoltage/overvoltage detection. |
| Propagation Delay | 2–4 μs - ensures rapid response to transient faults in safety-critical power sequencing applications. |
| Hysteresis | 2–8 mV - suppresses noise-induced chatter in noisy industrial environments without external feedback resistors. |
| Input Common-Mode Range | –0.2 V to (V+) + 0.2 V - supports detection of signals beyond supply rails, e.g., battery cell monitoring above system VCC. |
| Operating Temperature | –55°C to 125°C - qualified for deployment in space-grade avionics, downhole oil/gas tools, and military vehicle ECUs. |
Pinout & Package
SOT-23-6 package (2.90 mm × 1.60 mm body size), surface-mount, lead-free, RoHS-compliant, qualified per MIL-PRF-38535 Class V standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Comparator output | Push-pull digital output capable of sourcing/sinking 5 mA - eliminates need for external pull-up resistor in most logic interfacing scenarios. |
| V− (Pin 2) | Negative supply | Ground reference terminal; input common-mode extends 200 mV below this node - supports single-supply operation with true ground-referenced sensing. |
| IN+ (Pin 3) | Non-inverting input | Rail-to-rail input stage accepts signals from V− − 0.2 V to V+ + 0.2 V - enables direct connection to unbuffered sensors or battery terminals. |
| IN− (Pin 4) | Inverting input | Matches IN+ in voltage range and bias current (<±10 pA) - ensures matched offset performance in differential threshold configurations. |
| REF (Pin 5) | Reference voltage output | Stable 1.242-V source with ≤100 ppm/°C drift - usable as precision reference for ADCs, DACs, or external comparators in same system. |
| V+ (Pin 6) | Positive supply | Accepts up to 7 V absolute max - provides margin for transient spikes in harsh electrical environments. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated hysteresis | Eliminates external RC feedback network required for noise immunity - reduces BOM count and PCB area in compact designs. |
| Fail-safe inputs | Guarantees valid comparator operation even when input signals exceed V+ or fall below V− - critical for battery cell voltage monitoring where pack voltage may float relative to system ground. |
| Power-on reset (POR) | Forces known output state during power-up - prevents spurious resets or false alarms in sequenced power systems. |
| Enhanced product (EP) qualification | Controlled baseline with single fab/assembly/test site, extended DMS support, and full life-cycle traceability - meets DoD, NASA, and ESA procurement requirements. |
| Low-input bias current | ±4.5 pA typical - preserves signal integrity when interfacing with high-impedance sources like thermistors or photodiodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012MDR | Commercial-grade version; not radiation-hardened or EP-qualified; same SOT-23-6 pinout and electrical specs. | Limited to non-safety-critical terrestrial applications; lacks extended temperature screening and DMS support. | Select only for cost-sensitive prototyping or ground-test fixtures where radiation tolerance and long-term supply continuity are not required. |
| V62/07604-01XE | Open-drain output variant (TLV3011-EP); identical reference, hysteresis, and temperature rating - but no push-pull drive or POR. | Suitable for wired-OR bus monitoring or applications requiring external pull-up control; cannot directly drive CMOS inputs without resistor. | Choose when system-level logic requires open-drain arbitration or when existing design uses TLV3011-EP footprint and only output topology differs. |
Compared with TLV3012MDR and V62/07604-01XE, the V62/23603-01XE uniquely combines radiation-hardened EP qualification, push-pull output with POR, and guaranteed hysteresis - making it the sole option for flight-ready power monitoring where deterministic startup and latch-up immunity are mandatory.

FAQ
What is the absolute maximum supply voltage rating for V62/23603-01XE?
The V62/23603-01XE has an absolute maximum supply voltage (V+ to V−) of 7 V. Exceeding this value risks permanent damage. Its recommended operating range is 1.65 V to 5.5 V, and the device maintains full specification compliance-including reference accuracy and propagation delay-across that range. Always observe the –0.5 V to 7 V limit on input pins relative to V−.
Does V62/23603-01XE require external hysteresis components?
No, V62/23603-01XE integrates 2–8 mV of hysteresis internally. This eliminates the need for external feedback resistors or capacitors typically used to stabilize comparator outputs in noisy environments. The hysteresis is factory-trimmed and remains stable across –55°C to 125°C, simplifying layout and improving long-term reliability in high-vibration or EMI-prone systems.
How does the power-on reset (POR) function in V62/23603-01XE?
The V62/23603-01XE includes a dedicated POR circuit that holds the OUT pin in a known logic-low state until the supply voltage reaches a valid operating level (~1.4 V) and stabilizes. This prevents undefined output states during power ramp-up, which is essential for deterministic sequencing in avionics and spacecraft power systems. The POR is fully integrated and requires no external components.
Can the REF pin of V62/23603-01XE drive external circuitry?
Yes, the REF pin delivers a stable 1.242-V output capable of sourcing or sinking up to 0.5 mA while maintaining ±0.25% initial accuracy and ≤100 ppm/°C drift. It can directly bias precision ADC references, set thresholds for secondary comparators, or calibrate sensor signal chains - eliminating the need for a separate voltage reference IC in resource-constrained designs.
Is V62/23603-01XE pin-compatible with commercial TLV3012 variants?
Yes, V62/23603-01XE uses the standard SOT-23-6 (DBV) package and shares identical pinout with TLV3012MDR and TLV3012IDBVR. All share the same terminal assignments: OUT, V−, IN+, IN−, REF, V+. However, due to its enhanced product qualification-including radiation hardening, extended temperature screening, and controlled manufacturing baseline-V62/23603-01XE is not a drop-in replacement without verifying system-level radiation and lifetime requirements.
