CAT1027LI-25-G

CAT1027LI-25-G Description

The CAT1027LI-25-G is a 2-channel voltage supervisor IC designed for power management applications. Manufactured by onsemi, this device is housed in an 8DIP package and features a through-hole mounting type. The CAT1027LI-25-G is designed to monitor two voltages with a threshold voltage of 2.55V, which is adjustable. It offers an open drain or open collector output and an active-low reset function with a minimum reset timeout of 130ms. This IC is categorized under Power Management (PMIC) and is suitable for applications requiring reliable voltage monitoring and system reset functionality.

CAT1027LI-25-G Features

• Voltage Monitoring: The CAT1027LI-25-G is capable of monitoring two different voltage levels, ensuring that both power supplies are within specified limits. This dual-channel monitoring is crucial for systems that require multiple power rails to be supervised.
• Adjustable Threshold Voltage: With a threshold voltage of 2.55V that can be adjusted, the CAT1027LI-25-G provides flexibility in setting the voltage levels at which the reset function is triggered. This adjustability allows for customization to fit specific application requirements.
• Open Drain/Open Collector Output: The device features an open drain or open collector output, which is ideal for interfacing with various types of logic circuits and ensuring compatibility with different system architectures.
• Active-Low Reset: The active-low reset function ensures that the system is reset when the monitored voltage falls below the threshold, providing a reliable mechanism for maintaining system integrity during power fluctuations.
• Minimum Reset Timeout: A minimum reset timeout of 130ms ensures that the system remains in a reset state long enough to stabilize after a power event, preventing premature system activation and potential instability.
• Through-Hole Mounting: The through-hole mounting type facilitates easy integration into printed circuit boards (PCBs) and ensures robust mechanical stability in various operating environments.
• Obsolete Status: While the product is marked as obsolete, it remains a reliable choice for legacy systems and applications where its specific features are required.

CAT1027LI-25-G Applications

The CAT1027LI-25-G is ideal for a variety of applications where reliable voltage monitoring and system reset are critical. These applications include:
