The CAT812RTBI-T is a Microprocessor Reset Circuit. It is designed to monitor the supply voltage of a microprocessor and assert a reset signal when the voltage falls below a certain threshold. This ensures that the microprocessor starts in a known state and avoids erroneous operation during power-up, power-down, or brownout conditions.

Applications

• Microprocessor-Based Systems: Providing reliable reset functionality for microprocessors.
• Embedded Systems: Ensuring proper startup and operation of embedded controllers.
• Industrial Control Systems: Monitoring power supply voltage in industrial equipment.
• Automotive Electronics: Supervising voltage levels in automotive control units.
• Consumer Electronics: Resetting microprocessors in various consumer devices.

Features

• Precision Voltage Monitor
• Active-Low Reset Output
• Guaranteed Reset Assertion at Low Voltage
• Low Supply Current
• Small SOT-23 Package
• RoHS Compliant

Benefits

• Ensures Reliable System Startup: Prevents the microprocessor from running on insufficient power.
• Protects Against Data Corruption: Prevents data corruption due to voltage drops.
• Simplifies System Design: Reduces the need for external reset circuitry.
• Low Power Consumption: Minimizes power consumption in battery-powered devices.
• Small Package: Allows for use in space-constrained applications.

Additional Details

The CAT812RTBI-T features an active-low reset output that remains asserted as long as the supply voltage is below the threshold. The device comes in a small SOT-23 package, making it easy to integrate into a variety of systems. It is designed to operate over a wide temperature range and is available in a variety of voltage thresholds to suit different application requirements.
