CAT825SSDI-GT3

Supervisors Overview

The CAT825SSDI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for surface-mount applications in an SC-70-5 package. It monitors a single input line and provides reset signals via open collector/drain and push-pull outputs. The device features manual reset capability without an integrated watchdog timer. It operates within a supply voltage range up to 6 V and supports a reset delay time of 200 ms. The component functions reliably across a temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Provides dual-output reset signaling through combined open collector and push-pull configurations for flexible interface compatibility.
• Includes manual reset functionality allowing external control over the reset state independent of monitored voltage levels.
• Supports single-input monitoring with configurable threshold detection for precise system supervision.

Supervisors Applications

• Portable electronic devices requiring compact voltage supervision
• Industrial control systems needing reliable power monitoring
• Consumer electronics utilizing low-profile surface-mount packaging

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics match design requirements. Confirm availability status as distribution channels may list discontinued or limited-stock items. Ensure compliance with RoHS directives if required by target market regulations. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a single-supervisor IC with mixed output types is required for space-constrained designs. The SC-70-5 package offers a small footprint suitable for dense PCB layouts. Consider the absence of a watchdog timer if complex timing sequences are needed elsewhere in the system. Evaluate the 200 ms reset delay against system startup requirements to ensure adequate stabilization time before processor initialization.

Supervisors Part Context

This part belongs to onsemi's standard product portfolio focused on signal conditioning and control solutions. The CAT825 series provides essential voltage monitoring capabilities for various industrial and consumer applications. These supervisory circuits help maintain system integrity by detecting power anomalies and initiating appropriate reset actions.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the same family that may offer updated manufacturing processes. Verify functional equivalence regarding output drive strength and reset delay times before substitution.
