What are the key features of STM1061N34WX6F?
- Fixed 3.332 V detection threshold requires no external resistors, simplifying PCB layout and reducing component count
- Micropower quiescent current extends battery runtime in portable and IoT devices monitoring a 3.3 V supply rail
- 3-pin SOT-23 package occupies minimal board area, fitting easily into handheld and wearable product designs
What is STM1061N34WX6F used for?
STM1061N34WX6F is used to monitor 3.3 V supply rails in microcontroller-based systems, asserting a reset or power-fail signal when the supply drops below 3.332 V. Its micropower design makes it ideal for battery-operated IoT sensors, wearables, and data loggers where quiescent current must be minimized to maximize battery life. The device is also used in EEPROM and flash memory write-protection circuits that require a reliable low-voltage lockout to prevent data corruption.

Frequently Asked Questions
What is the detection threshold of STM1061N34WX6F, and how accurately does it monitor a 3.3 V rail?
STM1061N34WX6F has a factory-trimmed threshold of 3.332 V with a typical accuracy of ±1.5%, meaning the output asserts between approximately 3.282 V and 3.382 V. This precision eliminates the tolerance stack-up of external resistor dividers used in adjustable detectors, improving brownout detection reliability in 3.3 V microcontroller power domains.
How does STM1061N34WX6F's 3-pin SOT-23 package affect placement near sensitive microcontroller power pins?
The 3-pin SOT-23 package measures approximately 1.3 mm × 2.9 mm, allowing it to be placed within 2 mm of the monitored VCC pin with minimal trace inductance between the supply and the detection input. This tight placement reduces the response delay to fast supply transients compared to a larger DIP or SOIC device mounted farther from the monitored rail.
When would a designer choose STM1061N34WX6F over an adjustable-threshold voltage detector for a 3.3 V application?
STM1061N34WX6F is preferred over an adjustable-threshold device when the 3.332 V threshold matches the target rail, because it eliminates 2 external resistors and removes resistor tolerance errors of ±1% per resistor that degrade threshold accuracy. In a high-volume production run with 10,000 boards, removing 2 resistors reduces assembly cost per board by approximately 0.02 USD and eliminates 2 potential failure points per unit.
