Key Features
- Fixed 3.6 V detection threshold with tight accuracy enables precise under-voltage lockout without external resistor dividers or trimming
- Ultra-low supply current below 5 µA minimizes battery drain in portable and energy-harvesting applications powered from coin cells or supercapacitors
- Compact SOT-23 3-pin package occupies less than 10 mm² of PCB area, freeing board space in space-constrained microcontroller and IoT designs
Applications
The STM1061N36WX6F is used to monitor 3.3 V supply rails in microcontroller-based systems, asserting a reset signal whenever voltage drops below 3.6 V to prevent corrupted program execution or EEPROM writes. It is well suited for battery-powered IoT nodes, wearable devices, and industrial sensor modules where supply current must remain below 5 µA at all times. The SOT-23 package facilitates integration into compact PCB layouts alongside LDO regulators and MCU reset lines.

Frequently Asked Questions
At what supply voltage does STM1061N36WX6F assert its reset output?
The STM1061N36WX6F asserts its open-drain reset output when the monitored supply voltage falls below 3.6 V. The detection threshold accuracy is typically within ±2%, meaning the actual trip point lies between 3.528 V and 3.672 V. This tight window ensures reliable under-voltage lockout for 3.3 V systems using LiPo batteries that discharge from 4.2 V down to approximately 3.0 V at end of life.
How does the STM1061N36WX6F compare to adjustable-threshold supervisors for fixed 3.3 V rail monitoring?
Unlike adjustable-threshold supervisors that require 2 external resistors (typically 100 kΩ each) to set the trip voltage, the STM1061N36WX6F uses an internal factory-trimmed 3.6 V reference, eliminating 2 components and saving approximately 5 mm² of board area. The tradeoff is that the threshold cannot be changed after manufacture, but for designs permanently powered from a 3.3 V rail, the fixed 3.6 V threshold provides suitable end-of-life detection without component variation from resistor tolerances.
Which low-power embedded designs benefit most from the STM1061N36WX6F's sub-5 µA consumption?
Battery-powered IoT nodes operating on 2 AA cells (nominal 3.0 V) and coin-cell powered RTC or memory backup circuits benefit most from the STM1061N36WX6F's supply current below 5 µA. In a system drawing 1 mA average from a 220 mAh CR2032 coin cell, adding the STM1061N36WX6F increases total current by less than 0.5%, extending battery life by a negligible amount while providing continuous 3.6 V brownout protection across the entire 220 mAh discharge cycle.
