STMicroelectronics 1 Voltage Supervisor 3-Pin 2.7 V SOT-23 STM1001RWX6F

STMicroelectronics STM1001RWX6F is a single-channel voltage supervisor integrated circuit designed to monitor supply voltages in electronic systems with precision and reliability. Housed in a compact 3-pin SOT-23 surface-mount package, this device is optimized for space-sensitive applications including portable battery-powered equipment, test instruments, desktop and notebook computers, and multi-output power supply units.

The supervisor monitors the supply voltage over the range of 1.2 V minimum to 5.5 V maximum, with a reset threshold voltage fixed at 2.7 V. Upon detecting voltage drops below this threshold, it provides an active low reset output via an open drain output driver, ensuring proper system resets and preventing malfunctions or erratic operation.

The device operates efficiently over a temperature range from -40°C to +85°C, making it suitable for both industrial and commercial electronics applications. Its compact dimensions of 3.04 mm length, 1.4 mm width, and 1.02 mm height allow easy integration on small PCBs without compromising board space.

This voltage supervisor does not include a watchdog timer or manual reset functionality, focusing solely on accurate voltage monitoring and reset signaling. The absence of automotive standard certification indicates it's tailored for general embedded electronics rather than automotive applications.

Applications include power supply voltage monitoring in microprocessor and microcontroller reset circuits, ensuring system integrity and preventing unpredictable behavior due to power anomalies. It supports design stability by providing a 280 ms reset active time delay, preventing false triggering due to transient voltage dips.

Monitors 1 voltage supervisor channel for precise reset threshold detection. Operates over a supply voltage range of 1.2 V to 5.5 V suitable for various power systems. Features an open drain, active low output driver compatible with many microcontroller inputs.

Designed for surface mount with a small 3-pin SOT-23 package for space-efficient PCB layouts. Resets system at 2.7 V reset threshold voltage with 280 ms reset active time for stability. Operates reliably in temperature range from -40°C to 85°C for industrial and commercial environments.
