Microchip Technology's MIC811SUTR Voltage Supervisor

The MIC811SUTR is a high-precision voltage supervisor designed to monitor power supplies in digital systems. Manufactured by Microchip Technology, a leader in microcontroller, mixed-signal, analog, and Flash-IP solutions, this device is an essential component for ensuring system reliability and stability. It is particularly suited for applications where an accurate and reliable monitoring of the power supply voltage is critical.

This voltage supervisor is designed to assert a reset signal whenever the VCC supply voltage falls below a preset threshold, ensuring that the microprocessor, microcontroller, or digital system resets cleanly during power-up, power-down, or brown-out conditions. The reset signal remains asserted for a period of time after VCC has risen above the reset threshold level, providing a stable reset to the processor when power returns to a safe level.

The MIC811SUTR comes in a compact SOT-143 package, making it an excellent choice for space-constrained applications. It features a low supply current, which makes it suitable for use in portable and battery-powered devices. The device's built-in hysteresis improves noise immunity, ensuring that the reset signal is free from false triggering due to supply voltage transients.

Key features of the MIC811SUTR include:

• Supply voltage supervision range tailored for 3.3V systems
• Low supply current, ideal for battery-operated devices
• Programmable reset timeout delay
• Immunity to short VCC transients
• Active-low RESET output
• High accuracy threshold voltage
• Temperature range suitable for commercial and industrial applications
• Compact SOT-143 package for space-saving designs

Applications that can benefit from the MIC811SUTR include:

• Computers and servers
• Embedded systems
• Portable and battery-powered equipment
• Industrial controllers
• Telecommunications systems

Microchip Technology's MIC811SUTR is a reliable solution for system designers looking to enhance the operational stability of their digital systems. With its precision voltage monitoring and low power consumption, it is an indispensable component for maintaining system integrity under varying power conditions.
