TC1232CPA

Supervisors Overview

The TC1232CPA is a microprocessor voltage monitor manufactured by Microchip Technology, housed in an 8-pin PDIP package for through-hole mounting. It features a single monitoring channel with manual reset capability and an integrated watchdog timer. The device monitors a supply voltage threshold of 4.62 V. Key electrical characteristics include a reset delay time of 1.2 seconds and a maximum operating supply voltage of 5.5 V. It supports power-fail detection and operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability
• Provides manual reset functionality
• Detects power failure conditions

Supervisors Applications

• Microprocessor supervisory circuits
• Embedded system voltage monitoring
• Industrial control unit protection

Supervisors Procurement Notes

Verify the specific suffix 'CPA' confirms the PDIP-8 package and 4.62V threshold variant. Ensure the application requires through-hole mounting compatible with this package style. Confirm that the 1.2s reset delay and 4.62V trip point align with the target circuit design requirements before procurement.

Supervisors Selection Notes

Select this component when a through-hole solution with integrated watchdog and manual reset is required. Compare against SOIC variants if surface mount space is limited. Verify that the 4.62V threshold matches the monitored rail voltage precisely. Consider the 1.2s reset delay duration relative to system startup timing constraints.

Supervisors Part Context

Part of the TC1232 series of supervisory circuits designed for microprocessor applications. This series typically offers configurable thresholds and output types across different package options including SOIC and DIP formats.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives such as other TC1232 variants with different thresholds or packages. Verify functional equivalence regarding watchdog timeout periods and reset delay times.
