Product Description

STMicroelectronics STM811RW16F Voltage Supervisor is a highly reliable microprocessor supervisory circuit engineered to monitor power supply voltages and provide manual reset capability. Packaged in a compact 4-pin SOT-143 form factor, the device features a reset threshold voltage of 2.7V and monitors supply voltages as low as 1V up to 5.5V, making it suitable for various electronic systems including desktop computers, portable equipment, and measurement instruments.

The device outputs active low push-pull signals, providing robust and noise-immune reset signals essential for microprocessor and microcontroller supervision. Its operational temperature range from -40°C to 85°C ensures performance stability in industrial and commercial applications.

This voltage supervisor is designed to protect digital circuits by detecting voltage drops and issuing resets with a 280 millisecond reset active time, preventing erratic system behavior during power fluctuations.

Featuring a surface mount package (SOT-143) with precise physical dimensions of 3.04 mm length, 1.4 mm width, and 1.02 mm height, it is suitable for compact electronic designs requiring reliable power supervision.

Manual reset functionality allows external control over reset state. Monitored voltage set at 2.63V ensures accurate voltage supervision. The robust push-pull output driver minimizes false triggering. Designed for single supervisor operation with pin count of 4.

Meets exacting electrical and temperature standards for professional use.

Typical applications include microprocessor power supply monitoring, embedded system supervision, battery-powered devices, and instrumentation. Industries such as consumer electronics, industrial controls, and automotive electronics benefit from integrating the STM811RW16F voltage supervisor.
