CAT809VTBI-GT3

CAT809VTBI-GT3 Description

The CAT809VTBI-GT3 is a single-channel voltage supervisor IC designed for power management applications. Manufactured by onsemi, this device is categorized under Power Management Integrated Circuits (PMICs). It features a compact SOT23-3 package, making it suitable for space-constrained designs. The CAT809VTBI-GT3 is designed to monitor a single voltage rail and provide a reset signal when the monitored voltage falls below a predefined threshold. This IC is particularly useful in applications where reliable power monitoring and system reset functionality are critical.

CAT809VTBI-GT3 Features

• Single Voltage Monitoring: The CAT809VTBI-GT3 is designed to monitor a single voltage rail, ensuring that the system remains stable and reliable. This single-channel monitoring is ideal for applications where only one power supply needs to be supervised.
• 1.6V Threshold Voltage: The device a has voltage threshold of 1.6V, which is suitable for low-voltage systems. This threshold ensures that the IC can accurately detect when the monitored voltage drops below the safe operating level.
• Active Low Reset Output: The reset output is active low, providing a clear and reliable signal to the system when a reset is required. This feature ensures that the system can quickly and effectively respond to voltage drops.
• 140ms Minimum Reset Timeout: The CAT809VTBI-GT3 has a minimum reset timeout of 140ms, providing ample time for the system to stabilize after a reset event. This timeout ensures that transient voltage drops do not cause unnecessary system resets.
• Surface Mount Technology: The CAT809VTBI-GT3 is available in a surface mount package, making it easy to integrate into modern PCB designs. The SOT23-3 package is compact and suitable for high-density applications.
• Moisture Sensitivity Level 1: With an MSL rating of 1 (unlimited), the CAT809VTBI-GT3 is highly resistant to moisture, making it suitable for a wide range of environmental conditions.
• Tape & Reel Packaging: The device is packaged in tape & reel (TR), which is ideal for automated assembly processes. This packaging method ensures that the ICs are handled efficiently and reliably during manufacturing.
