ON Semiconductor CAT824STDI-GT3 Voltage Supervisor IC

The ON Semiconductor CAT824STDI-GT3 is a precision voltage supervisor IC designed to keep microprocessor systems safe by monitoring the power supply voltage. This compact and efficient component is essential for applications where consistent and reliable system operation is critical, especially during power-up, power-down, and brown-out conditions. The CAT824STDI-GT3 ensures that the system's microprocessor or microcontroller resets properly during these events, thus preventing code execution errors and potential system failures.

Featuring a fixed sense threshold voltage of 4.63V, the CAT824STDI-GT3 is suitable for use with 5V systems. The device boasts a ±1.5% threshold accuracy, which provides a precise monitoring capability for systems that cannot tolerate significant voltage deviations. The component's low 20nA (typical) standby current makes it an ideal choice for battery-powered or energy-efficient applications, where power conservation is paramount.

One of the key features of the CAT824STDI-GT3 is its built-in manual reset input. This allows for an external signal to trigger a system reset, offering additional flexibility and control to the user. The reset timeout period is internally fixed at 140ms (minimum), ensuring that the system has adequate time to stabilize before normal operation resumes.

The device is packaged in a compact SOT-143 surface-mount package, which is ideal for space-constrained applications. Its operating temperature range of -40°C to +85°C allows for deployment in a wide range of environments, from industrial settings to consumer electronics.

As part of ON Semiconductor's commitment to environmental sustainability, the CAT824STDI-GT3 is also RoHS compliant, minimizing the environmental impact by excluding hazardous substances from its manufacturing process. With its combination of precision, low power consumption, and compact form factor, the CAT824STDI-GT3 voltage supervisor IC is a reliable and eco-friendly solution for safeguarding your electronic systems.
