Product details
Overview
STM1061N17WX6F from STMicroelectronics is a low-power, factory-trimmed voltage detector IC with 1.7V ±2% threshold, open-drain active-low output, 0.9µA typical supply current, and guaranteed operation down to VCC = 0.7V. It monitors power rails in portable and battery-powered systems, asserting reset when supply voltage drops below threshold and maintaining assertion through hysteresis (VHYST = 0.02–0.08×VTH–) to prevent chatter during brownout recovery.
For engineers reviewing the STM1061N17WX6F datasheet, STM1061N17WX6F pinout, STM1061N17WX6F application, or STM1061N17WX6F equivalent, this device serves as a precision, ultra-low-quiescent monitoring solution for microcontroller reset supervision, DC/DC converter enable control, and battery voltage validation in space-constrained embedded designs.
Technical Context
The STM1061N17WX6F implements a precision bandgap reference and comparator architecture to detect VCC falling below 1.7V (±2% at 25°C), with hysteresis of 0.034V (2% of 1.7V). Its N-channel open-drain output sinks up to 30mA at VCC = 5V and remains functional down to 0.7V supply - enabling reliable reset assertion even during deep brownout conditions.
It features transient immunity against negative-going VCC glitches (e.g., ≤100µs duration for 100mV overdrive), operates across –40°C to +85°C, and supports pull-up to any voltage ≤6V independent of VCC - enabling flexible interfacing with diverse logic families and voltage domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Threshold | 1.7V ±2% at 25°C; factory-trimmed for accuracy without external calibration |
| Supply Current | 0.9µA typ at 3.0V; enables multi-year battery life in always-on monitoring |
| Operating Voltage Range | 0.7V to 6.0V; guarantees correct output state even during severe undervoltage |
| Output Type | Open-drain active-low; supports wired-OR reset buses and level-shifting via external pull-up |
| Hysteresis | 0.034V (2% of VTH–); prevents false releases during slow or noisy supply recovery |
| Detect Delay | 25µs max (VCC fall at 10mV/µs); ensures timely reset assertion before system instability |
| Release Delay | 30–200µs (VCC rise at 10mV/µs); provides controlled release timing after threshold crossing |
Pinout & Package
STM1061N17WX6F is housed in a RoHS-compliant SOT23-3 (WX) package - a 3-pin, surface-mount, lead-free outline measuring 2.9mm × 1.3mm × 1.0mm (D × E × A2), optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Open-drain active-low output | Sinks current when VCC < VTH–; requires external pull-up resistor (e.g., 10kΩ) to define logic-high level |
| 2 (VCC) | Supply input and voltage sense node | Monitored rail input; powers internal circuitry and defines detection reference |
| 3 (VSS) | Ground reference | System ground return path; must be low-impedance and co-located with bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed threshold | 1.7V set at wafer test; eliminates need for external resistor divider or trimming |
| Ultra-low ICC | 0.9µA typical at 3V; reduces standby power in battery-backed systems by >95% vs. legacy reset ICs |
| VCC-down-to-0.7V guarantee | Valid output assertion even when supply collapses below 1.0V - critical for Li-ion end-of-discharge detection |
| Transient immunity | Immune to <100µs negative VCC glitches ≥100mV below threshold - suppresses false resets from switching noise |
| Wide temperature range | –40°C to +85°C operation with ±100 ppm/°C threshold drift - suitable for industrial and automotive cabin environments |
Applications
| Microcontroller Reset Supervision | DC/DC Converter Enable Control |
|---|---|
|
Use Scenario: Ensuring clean boot and safe shutdown of an ARM Cortex-M0 MCU powered from a 3.3V LDO. IC Role / Device Role / Timing Role: Voltage detector asserts active-low reset until VCC stabilizes above 1.7V and remains asserted for ≥25µs detect delay. Use Value: Prevents code execution from corrupted memory during power ramp-up; hysteresis avoids oscillation near threshold during LDO settling. |
Use Scenario: Enabling a buck converter only when input battery voltage exceeds 1.7V to avoid under-voltage operation. IC Role / Device Role / Timing Role: OUT drives EN pin low (via pull-up) until battery reaches threshold; release delay ensures stable enable after recovery. Use Value: Eliminates need for discrete comparator + MOSFET; open-drain output allows direct connection to 5V-enable logic while powered from 1.8V rail. |
| Portable Device Battery Monitoring | Low-Power Sensor Node Wake-Up |
|
Use Scenario: Detecting end-of-life voltage in a coin-cell–powered BLE beacon using CR2032 (nominal 3.0V). IC Role / Device Role / Timing Role: Monitors battery directly; asserts reset when cell drops to 1.7V ±2%, triggering graceful shutdown sequence. Use Value: 0.9µA ICC extends usable battery life by months; guaranteed 0.7V operation captures final discharge phase before cutoff. |
Use Scenario: Waking an ultra-low-power environmental sensor from sleep when main supply recovers after interruption. IC Role / Device Role / Timing Role: OUT connected to MCU's wake-up interrupt pin; detects VCC rise above 1.7V and holds interrupt active for ≥30µs. Use Value: Enables deterministic wake-up without polling; open-drain interface isolates sensor domain (1.8V) from host domain (3.3V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB17DPWR | 1.7V threshold, ±1% accuracy, 350nA ICC, SOT23-3, but no guaranteed operation below 1.0V | Lacks VCC-down-to-0.7V guarantee; unsuitable for deep brownout detection in Li-ion systems | Select if higher accuracy and lower ICC are prioritized over sub-1V assertion capability |
| MAX809SEUR+T | 1.63V threshold, ±2.5% accuracy, 12µA ICC, SOT23-3, push-pull output | Higher quiescent current; push-pull output limits voltage-domain flexibility vs. open-drain | Select if board already uses push-pull reset topology and 12µA ICC is acceptable in target application |
Compared with TLV803EB17DPWR and MAX809SEUR+T, STM1061N17WX6F uniquely combines sub-1V assertion guarantee, ultra-low 0.9µA ICC, and open-drain flexibility - making it optimal for battery-critical, multi-rail, and space-constrained designs where reliability at extreme low voltage is non-negotiable.

FAQ
What is the exact voltage threshold and tolerance for STM1061N17WX6F?
The STM1061N17WX6F has a factory-trimmed detect voltage (VTH–) of 1.700V at 25°C, with a guaranteed tolerance of ±2% across temperature and process variation - meaning the actual threshold falls between 1.666V and 1.734V under all operating conditions per datasheet Table 9.
Can STM1061N17WX6F drive a standard 3.3V logic input directly?
No - its open-drain output requires an external pull-up resistor to a defined logic-high voltage (e.g., 3.3V). With a 10kΩ pull-up to 3.3V, it delivers a valid logic-low (<0.4V) when asserted and logic-high (~3.3V) when released, fully compatible with standard CMOS inputs.
Does STM1061N17WX6F require a bypass capacitor on VCC?
Yes - a 0.1µF ceramic capacitor placed as close as possible to the VCC pin is explicitly recommended in the datasheet (Section 3.2) to enhance immunity against fast negative transients and ensure stable internal reference operation during load switching events.
Is STM1061N17WX6F qualified for automotive applications?
No - it is rated for –40°C to +85°C operation and is not AEC-Q100 qualified. While it meets industrial temperature requirements, ST offers automotive-grade alternatives (e.g., STM1061xxQ variants) with extended qualification, enhanced ESD, and PPAP documentation for vehicle systems.
