CAT809SSDI-GT3 Description

The CAT809SSDI-GT3 is a 1-channel power supply supervisor IC from onsemi, designed to monitor a single voltage source and provide reliable reset functionality. This device is housed in a compact SC70-3 package, making it suitable for space-constrained applications. Despite its small form factor, the CAT809SSDI-GT3 offers robust performance and features that make it an ideal choice for a variety of electronic systems.

CAT809SSDI-GT3 Features

• Single Voltage Monitoring: The CAT809SSDI-GT3 is designed to monitor a single voltage source, ensuring that it remains within specified limits. This is particularly useful in applications where a single power rail needs to be monitored for stability.
• Active Low Reset: 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 be safely and effectively reset in the event of a power anomaly.
• 2.93V Threshold Voltage: The device has a voltage threshold of 2.93V, which is ideal for monitoring power supplies that operate around this voltage level. This precise threshold helps in accurately detecting voltage drops and ensuring system reliability.
• 140ms Minimum Reset Timeout: The reset timeout is set to a minimum of 140ms, providing sufficient time for the system to stabilize after a reset event. This ensures that the system can recover from power anomalies without premature reactivation.
• Surface Mount Packaging: The CAT809SSDI-GT3 is available in a surface mount package, making it easy to integrate into modern printed circuit board (PCB) designs. The SC70-3 package is small and efficient, conserving valuable board space.
• Moisture Sensitivity Level 1: With a moisture sensitivity level (MSL) of 1, the device is classified as unlimited, meaning it can be exposed to environmental conditions without the need for special handling or packaging.
• REACH Unaffected and EAR99 Classification: The CAT809SSDI-GT3 complies with REACH regulations and is classified under ECCN EAR99, ensuring that it meets environmental and export control standards.
