ON Semiconductor CAT823RTDI-GT3 Voltage Supervisor IC

The CAT823RTDI-GT3 is a precision voltage supervisor device designed by ON Semiconductor, a leading figure in the semiconductor industry. This compact and efficient component is engineered to ensure reliable system operation through its monitoring of power supply voltages. The CAT823RTDI-GT3 is an essential component for a wide range of electronic applications, particularly those that require a high degree of stability and accuracy in power supply monitoring.

With a specific focus on safeguarding against unpredictable system behavior due to power fluctuations, this voltage supervisor IC is adept at providing the necessary control. It features a fixed sense threshold voltage of 2.93V, which is ideal for 3V systems, and a ±1.5% threshold accuracy that is maintained over the entire temperature range of -40°C to +85°C. This precision ensures that systems are consistently monitored and protected against undervoltage conditions.

The CAT823RTDI-GT3 is housed in a small 4-pin SOT-143 package, making it suitable for space-constrained applications. Despite its compact size, it does not compromise on performance, offering a low supply current of 9 µA, which is highly beneficial for power-sensitive designs. Its active-low reset output remains asserted for a minimum of 140 ms after V_CC has risen above the reset threshold, ensuring a proper system reset and stabilization.

This voltage supervisor IC also features a built-in manual reset input, allowing for a system reset to be triggered with an external pushbutton or logic signal. This adds an extra layer of control for system designers and operators, providing the ability to manually initiate a system reboot or shutdown when necessary.

In conclusion, the CAT823RTDI-GT3 from ON Semiconductor is a robust and reliable solution for systems that require vigilant voltage supervision. It combines precision, low power consumption, and a small form factor, making it a versatile choice for applications ranging from consumer electronics to industrial control systems. By integrating this IC into your design, you can enhance the overall stability and safety of your electronic systems.
