ON Semiconductor CAT823YTDI-GT3 Voltage Supervisor

The CAT823YTDI-GT3 is a high-performance, precision voltage supervisor designed to ensure the stability and reliability of electronic systems. Manufactured by ON Semiconductor, a leading supplier in the semiconductor industry, this component is crucial for applications that require strict voltage monitoring and power management.

This voltage supervisor is designed to monitor VCC for under-voltage conditions and ensure that the system microprocessor is reset accurately and reliably. It features a fixed sense threshold voltage of 2.93V, which makes it suitable for 3.3V-powered systems. The CAT823YTDI-GT3 is particularly well-suited for battery-powered equipment, portable electronics, microcontrollers, and other systems where power conditions need to be managed with precision.

The device comes in a compact, 5-lead TSOT-23 package, which is ideal for space-constrained applications. It offers several key features, including a low quiescent current of 5 µA, making it an energy-efficient option for portable devices. Additionally, it provides a 140 ms minimum power-on reset pulse width, which ensures that the system has sufficient time to stabilize before the processor starts operating.

The CAT823YTDI-GT3 also includes a manual reset input, which allows for a system reset to be initiated by external hardware or software control. This flexibility is essential for systems that require user-initiated resets or for those that need to implement a reset sequence as part of a maintenance routine or error recovery process.

With its built-in hysteresis to prevent erratic operation in the presence of noise, the CAT823YTDI-GT3 is designed for robust performance in a wide range of operating conditions. It is a critical component for ensuring that systems run smoothly and without interruption, contributing to the overall reliability and longevity of electronic products.

In summary, the CAT823YTDI-GT3 from ON Semiconductor is a versatile and reliable voltage supervisor that is an essential part of power management in modern electronic devices. Its precision, low power consumption, and compact form factor make it an excellent choice for designers looking to enhance system stability and performance.
