ON Semiconductor CAT809TEUR-T Voltage Supervisor

The CAT809TEUR-T from ON Semiconductor is a high-performance microprocessor supervisory circuit designed to keep systems within their operational voltage limits. This precision voltage supervisor device is essential for applications that require a high degree of reliability and accuracy, such as embedded systems, portable electronics, and microcontroller-based applications.

The CAT809TEUR-T is engineered to monitor the supply voltage of digital systems and provide a reset signal to the host processor when necessary. It ensures that the system resets in a predictable manner during power-up, power-down, or if the supply voltage drops below a predetermined threshold. This feature is crucial for preventing system errors and data corruption that can occur during unexpected voltage variations.

Key Features:

• Precision Monitoring: With a tight monitoring threshold accuracy of ±1.5%, this device ensures reliable operation by providing a stable reset signal over the full temperature range.
• Low Power Consumption: The CAT809TEUR-T is optimized for low-power applications, drawing minimal current from the supply, thereby extending battery life in portable devices.
• Manual Reset Input: An additional manual reset input allows users to trigger a system reset with an external signal, providing an extra layer of control.
• Reset Timeout: It features an internally fixed delay time for the reset signal, ensuring that the system has sufficient time to stabilize before normal operation resumes.
• Temperature Range: The device operates over a wide temperature range, making it suitable for use in diverse environmental conditions.
• Compact Packaging: Available in a space-saving 3-pin SOT-23 package, the CAT809TEUR-T is ideal for applications where board space is at a premium.

Applications for the CAT809TEUR-T are vast and include portable devices, computers, controllers, intelligent instruments, and critical microcontroller power monitoring. By incorporating the CAT809TEUR-T into their designs, engineers can ensure system stability and protect against the consequences of unpredictable power supply conditions.

With the CAT809TEUR-T, ON Semiconductor continues to demonstrate its commitment to providing robust and reliable components that meet the stringent requirements of modern electronic systems.
