CAT823TDI-GT3

CAT823TDI-GT3 Description

The CAT823TDI-GT3 is a single-channel voltage supervisor IC designed to monitor power supply voltages in various electronic systems. Manufactured by onsemi, this device is housed a in TSOT23-5 package, making it suitable for surface-mount applications. Despite its obsolete status, the CAT823TDI-GT3 remains a reliable choice for applications requiring precise voltage monitoring.

CAT823TDI-GT3 Features

• Single-Channel Voltage Monitoring: The CAT823TDI-GT3 is designed to monitor a single voltage rail, providing accurate and reliable supervision. This feature is particularly useful in systems where a single critical voltage needs to be monitored to ensure proper operation.
• 3.08V Threshold Voltage: With a threshold voltage of 3.08V, the CAT823TDI-GT3 offers precise monitoring capabilities. This specific threshold ensures that the device can accurately detect voltage drops below this level, triggering a reset if necessary.
• Active Low Reset Output: The reset output of the CAT823TDI-GT3 is active low, which is a common requirement in many digital systems. This feature allows for seamless integration with other components that require a low signal to initiate a reset.
• 140ms Minimum Reset Timeout: The device features a minimum reset timeout of 140 milliseconds. This ensures that the system remains stable and prevents premature resets, which can be critical in applications where a brief voltage dip should not cause a system-wide reset.
• Surface Mount Technology (SMT): The CAT823TDI-GT3 is designed for surface-mount applications, making it ideal for modern PCB designs. The TSOT23-5 package is compact and suitable for high-density layouts, ensuring efficient use of board space.
• Moisture Sensitivity Level (MSL) 1: With an MSL rating of 1, the CAT823TDI-GT3 is classified as unlimited, meaning it can be exposed to moisture without significant risk of damage. This feature enhances the device's reliability in various environmental conditions.
• Compliance and Standards: The CAT823TDI-GT3 is REACH unaffected and classified under ECCN EAR99, ensuring compliance with international regulations and standards. This makes it suitable for a wide range of applications without regulatory concerns.

CAT823TDI-GT3 Applications

The CAT823TDI-GT3 is ideal for applications requiring precise voltage monitoring and reliable reset functionality. Some specific use cases include:

• Power Supply Monitoring: In power supply units (PSUs), the CAT823TDI-GT3 can monitor the main voltage rail to ensure it remains within safe operating limits. If the voltage drops below the threshold, the device can trigger a reset to prevent damage to connected components.
• Embedded Systems: In embedded systems, such as microcontrollers and microprocessors, the CAT823TDI-GT3 can monitor the power supply voltage to ensure stable operation. This is crucial in applications where a voltage drop could lead to system instability or data corruption.
• Telecommunications Equipment: In telecom equipment, the CAT823TDI-GT3 can be used to monitor critical voltage levels, ensuring reliable operation and preventing system failures due to power supply issues.
• Industrial Control Systems: In industrial settings, the CAT823TDI-GT3 can be integrated into control systems to monitor power supply voltages and provide a reset function if necessary. This helps maintain system integrity and prevent downtime.
