The STM802BDR is a sophisticated microprocessor reset circuit developed by STMicroelectronics, designed to monitor the supply voltage of microprocessor (µP) systems, providing a reliable reset signal to the µP whenever necessary. This device is an essential component for any system that requires a high degree of operational reliability and resilience to power supply fluctuations.

Key Features

• Precision Monitoring: The STM802BDR offers precise monitoring of the 3.3V power supply with a threshold accuracy of ±1.5% at 25°C, ensuring that the µP is reset with accuracy and reliability.
• Low Power Consumption: It is designed to be energy-efficient, consuming minimal power, which is crucial for battery-operated devices.
• Manual Reset Input: This device includes a manual reset input that allows for a system reset to be initiated by the user or another system event.
• Reset Time Delay: It features an internally fixed delay time which provides a reset signal for approximately 200ms after the supply voltage has risen above the reset threshold level, ensuring system stability during power-up.
• High Immunity to Transients: The STM802BDR is highly immune to fast transient glitches on the VCC line, which helps to prevent false resets from occurring.
• Operating Temperature Range: It operates over an extended temperature range of -40°C to 85°C, suitable for industrial applications.
• RoHS Compliant: The device is fully RoHS compliant, adhering to environmental standards and regulations.
