STMicroelectronics Voltage Supervisor 1 Supervisor 2.7 V Reset Threshold SOT-23 3-Pin STM809RWX6F

STMicroelectronics STM809RWX6F is a voltage supervisor integrated circuit designed for microprocessor supply voltage monitoring and reset management. It features a single supervisory channel in a compact 3-pin SOT-23 surface mount package with a reset threshold voltage of 2.7 V.

This device operates over a supply voltage range of 1 V to 5.5 V, making it suitable for various electronic applications including desktop and portable battery-powered systems. The output driver is active low with a push-pull configuration, providing reliable reset signaling to ensure microprocessor stability.

With a monitored voltage of 2.63 V and a reset active time of 280 ms, the STM809RWX6F assures timely reset under voltage failure conditions, which is critical for maintaining system integrity. It supports an operating temperature range from -40°C to 85°C, enabling use in industrial and commercial environments.

The small physical dimensions - 3.04 mm length, 1.4 mm width, and 1.02 mm height - allow easy integration on printed circuit boards where space is limited. The device features no watchdog timer or manual reset, simplifying its implementation in microprocessor supervisory circuits. It complies with no specific automotive or industrial standards but is ideal for power supply supervision tasks.

Common industrial applications include system voltage monitoring in desktop computers, laptops, notebook computers, test and measurement instruments, and multiple-output power supplies.
