The CAT811RTBI-T3 is a microprocessor supervisory circuit designed to monitor the supply voltage in microprocessor-based systems. It provides a reset output when the supply voltage falls below a specified threshold, preventing erratic operation and data corruption. The device features a precise voltage threshold and a low supply current.

Applications

• Microprocessor-based systems
• Embedded controllers
• Industrial control equipment
• Automotive electronics
• Consumer electronics

Features

• Precision Voltage Monitoring
• Active-High Reset Output
• Manual Reset Input
• Low Supply Current
• No External Components Required
• Small Package: SOT-23
• Wide Operating Temperature Range

Benefits

• Prevents microprocessor malfunction due to low voltage
• Ensures reliable system operation
• Reduces system complexity and cost
• Simple to implement and use
• Manual reset allows for system reset independent of voltage level

The CAT811RTBI-T3 monitors the supply voltage and asserts a reset signal when the voltage drops below the threshold. The reset signal remains asserted until the voltage rises above the threshold and a reset timeout period has elapsed. The active-high reset output and manual reset input provide additional flexibility in system design. The device requires no external components, simplifying the design process and reducing system cost. The CAT811RTBI-T3 is available in a small SOT-23 package and is often used in a broad range of applications from embedded systems to control equipment for voltage supervision.
