Product details
Overview
STM1061N23WX6F from STMicroelectronics is a low-power, factory-trimmed voltage detector IC with 2.3V ±2% threshold, open-drain active-low output, 0.9µA typical supply current, and guaranteed operation down to VCC = 0.7V. It monitors battery or regulated supply rails in portable electronics and embedded systems requiring precise reset assertion during brownout conditions.
For engineers reviewing the STM1061N23WX6F datasheet, STM1061N23WX6F pinout, STM1061N23WX6F application, or STM1061N23WX6F equivalent, key selection criteria include threshold accuracy, ultra-low ICC, open-drain flexibility for wired-OR reset networks, and transient immunity in space-constrained SOT23-3 packaging.
Technical Context
The device uses an internal precision voltage reference and comparator to continuously monitor VCC against a fixed 2.3V detect threshold (VTH–), asserting OUT low when VCC falls below VTH– and holding until VCC rises above VTH+ (VTH– + hysteresis). Hysteresis is factory-set at 0.02–0.08×VTH–, ensuring noise immunity during recovery.
Its N-channel open-drain output sinks up to 30mA at VCC = 5.0V (VDS = 0.5V) and remains functional down to 0.7V supply, enabling reliable reset generation even during deep brownout. Transient immunity is enhanced by internal design and supported by external 0.1µF bypass capacitance at VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Threshold | 2.30V ±2% at 25°C - ensures accurate brownout detection with minimal tolerance drift across temperature |
| Supply Current | 0.9µA typ at 3.0V - enables multi-year battery life in always-on monitoring applications |
| Operating Voltage | 0.7V to 6.0V - supports operation during severe undervoltage and compatibility with 1.8V–5V system rails |
| Output Type | Open-drain active-low - allows level-shifting, wired-OR reset buses, and pull-up to independent voltage rail ≤6V |
| Hysteresis | 0.046V (2% of 2.3V) min - prevents chatter during slow-rising/falling supply transitions |
| Temp Range | –40°C to +85°C - qualified for industrial and extended commercial environments |
| Delay Times | tPD = 25µs max, tPR = 30–200µs - provides deterministic reset timing without external RC components |
Pinout & Package
SOT23-3 package: 3-pin surface-mount, 2.8mm × 2.1mm footprint, ECOPACK® lead-free, tape-and-reel delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Open-drain active-low output | Sinks current when VCC < VTH–; requires external pull-up; compatible with 1.8V–6V logic domains |
| 2 (VCC) | Supply input & monitored rail | Input voltage source for internal circuitry and detection; valid from 0.7V to 6.0V |
| 3 (VSS) | Ground reference | System ground return path; must be low-impedance connection for stable threshold accuracy |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed threshold | 2.3V set at wafer test with ±2% accuracy - eliminates need for external resistor dividers or calibration |
| Ultra-low quiescent current | 0.9µA typical - reduces standby power in battery-powered IoT sensors and wearables |
| Sub-1V operation guarantee | Valid output assertion down to VCC = 0.7V - ensures last-cycle reset before complete power collapse |
| Transient immunity | Immune to fast negative-going VCC glitches per Figure 11 - avoids spurious resets in noisy DC/DC environments |
| Two-package option | SOT23-3 (WX) and SOT323-3 (W) - enables layout flexibility for density vs. assembly compatibility trade-offs |
Applications
| Battery-Powered Wearables | Industrial Sensor Nodes |
|---|---|
Use Scenario: A coin-cell–powered temperature sensor transmits data every 5 minutes and sleeps between readings. IC Role / Device Role / Timing Role: Voltage detector asserts reset if battery drops below 2.3V, preventing corrupted EEPROM writes or MCU lockup during low-VBAT states. Use Value: Prevents data corruption and extends usable battery life by enabling graceful shutdown before brownout-induced firmware faults. | Use Scenario: A 4–20mA loop-powered pressure transmitter operates unattended in remote oil-field equipment cabinets. IC Role / Device Role / Timing Role: Monitors regulated 3.3V rail derived from loop supply; triggers hardware reset on undervoltage caused by cable voltage drop or regulator failure. Use Value: Ensures deterministic recovery without host intervention, maintaining field reliability over 10+ year deployments. |
| Medical Diagnostic Handhelds | Smart Energy Meters |
Use Scenario: A portable ECG reader uses dual AA batteries and must retain calibration settings across power cycles. IC Role / Device Role / Timing Role: Generates clean, glitch-free reset pulse to MCU and analog front-end when supply sags below 2.3V during high-current LED flash or ADC burst sampling. Use Value: Guarantees consistent startup behavior and preserves nonvolatile memory integrity during intermittent power dips. | Use Scenario: A DIN-rail mounted electricity meter experiences wide input fluctuations due to grid harmonics and transformer tap changes. IC Role / Device Role / Timing Role: Supervises isolated 3.3V microcontroller supply; ignores sub-µs transients but asserts reset on sustained undervoltage >25µs. Use Value: Eliminates false resets while ensuring fail-safe response to genuine loss-of-supply events per IEC 62053 compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB23DBZR | 2.3V threshold, ±1% accuracy, 350nA ICC, SOT23-3 - tighter tolerance but lower drive strength (5mA sink) | Lower power but insufficient for driving heavy reset loads or long PCB traces | Select when ultra-low ICC dominates over output drive; verify pull-up sizing for logic-level compatibility |
| MAX809SEUR+T | 2.3V threshold, ±2.5% accuracy, 12µA ICC, SOT23-3 - higher supply current, no sub-1V operation guarantee | Lacks guaranteed function below 1.0V; less suitable for deep-brownout detection | Choose only if legacy qualification or pin-compatibility with existing MAX809-based designs is required |
Compared with TLV803EB23DBZR and MAX809SEUR+T, STM1061N23WX6F uniquely balances ±2% threshold accuracy, sub-1V operation guarantee, and 30mA sink capability - making it optimal for cost-sensitive industrial and portable designs needing robust reset under worst-case supply collapse.

FAQ
What is the exact voltage threshold and tolerance for STM1061N23WX6F?
The STM1061N23WX6F has a factory-trimmed detect threshold (VTH–) of 2.30V with ±2% accuracy over –40°C to +85°C, corresponding to a range of 2.254V to 2.346V at 25°C per Table 9. This tolerance includes initial accuracy and temperature drift (±100 ppm/°C), verified across full operating temperature range.
Can STM1061N23WX6F drive a 10kΩ pull-up to 5V reliably?
Yes. With 22mA typical sink current at VCC = 3.0V (VDS = 0.5V), the device pulls OUT to <0.4V when asserted - well within TTL/CMOS low-level specs for 5V logic. A 10kΩ pull-up yields ~50µA load, far below the 22mA capability, ensuring robust low-state margin even at temperature extremes.
Does STM1061N23WX6F require an external capacitor for stability?
No external capacitor is needed for basic voltage detection, but a 0.1µF ceramic bypass capacitor placed close to the VCC pin is recommended to enhance immunity to fast negative-going transients per Figure 11 and Section 3.2. This improves noise rejection without affecting detection threshold or delay timing.
Is STM1061N23WX6F pin-compatible with other STM1061 variants?
Yes - all STM1061 variants (e.g., STM1061N16WX6F, STM1061N34WX6F) share identical SOT23-3 pinout (OUT/VCC/VSS), same electrical interface, and identical timing characteristics. Only the factory-trimmed threshold voltage differs; no PCB redesign is needed when changing threshold options.
