CAT810JSDI-GT3

Supervisors Overview

The CAT810JSDI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single-channel power supplies. It operates within a supply voltage range of 1.2 V to 5.5 V and features an active high push-pull output. The device triggers at a threshold voltage of 4 V, with specific under-voltage and over-voltage thresholds of 3.93 V and 4.06 V respectively. It includes a fixed reset delay time of 240 ms and consumes only 8 uA of operating current. Packaged in a SC-70-3 (SOT-323) surface-mount format, it supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable power supply supervision with active high push-pull output capability
• Maintains low power consumption suitable for battery-operated applications
• Ensures system stability through precise voltage threshold detection and defined reset delays

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing voltage level monitoring

Supervisors Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to ensure correct package type and tape/reel specifications. Confirm that the GT3 suffix aligns with current production status and availability constraints. Cross-reference the part number with authorized distributors to validate authenticity and compliance with regional regulatory standards such as RoHS requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with active high output is required. Ensure the 4 V threshold matches the monitored rail voltage. Consider the SC-70-3 package size for space-constrained designs. Verify that the 240 ms reset delay meets the system startup timing requirements. Check compatibility with the target operating temperature range and supply voltage limits.
