CAT824RSDI-GT3

Supervisors Overview

The CAT824RSDI-GT3 is a fixed-channel power supply management circuit manufactured by onsemi. It operates within a voltage range of 1.2 V to 5.5 V and features a reset threshold voltage of 2.63 V. The device utilizes a TSOT-23-5 package with five pins and supports an operating temperature range from -40 °C to +85 °C. It is RoHS compliant and classified under the CAT824 series of supervisory circuits.

Supervisors Feature Summary

• Provides fixed voltage supervision for single-channel power rails
• Integrates watchdog timer functionality for system reliability
• Supports floating gate configuration for flexible output states

Supervisors Applications

• Embedded system power monitoring
• Industrial control unit supervision
• Consumer electronics voltage regulation

Supervisors Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm datasheet revision matches design requirements. Ensure ESD handling protocols are followed during storage and assembly. Validate package marking against official specifications to prevent counterfeit infiltration.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-rail monitoring. The TSOT-23-5 package suits space-constrained designs. Consider the integrated watchdog feature if system stability depends on automated fault recovery without external logic.

Supervisors Part Context

Part of the CAT824 family, which offers various supervisory solutions. This specific variant focuses on fixed-threshold applications with watchdog capabilities. It complements other onsemi PMICs in comprehensive power management architectures.

Supervisors Replacement Considerations

CAT824MTDI-GT3 and CAT824UTDI-GT3 are related variants within the same series. Verify threshold voltage compatibility (4.38 V vs 2.63 V) before substitution. Package and pinout similarities exist, but functional parameters differ significantly.
