CAT1162WI-30-T3

Supervisors Overview

The CAT1162WI-30-T3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 2.7 V to 6 V and features a fixed threshold voltage of 3 V. The device provides a reset delay time of 270 ms and supports manual reset functionality. It is available in an SOIC-Wide-8 surface-mount package with active high, active low, and open drain output options. The component includes 16 Kbit EEPROM storage and lacks a watchdog timer or battery backup switch.

Supervisors Feature Summary

• Integrates 16 Kbit EEPROM for non-volatile data storage alongside voltage supervision.
• Provides flexible output configurations including active high, active low, and open drain signals.
• Supports manual reset input for controlled system recovery.

Supervisors Applications

• CPU power supply monitoring
• Embedded system voltage supervision
• Data retention management via integrated EEPROM

Supervisors Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited distribution. Confirm package variant matches design requirements. Check RoHS compliance documentation. Validate operating temperature range suitability. Review official datasheet for latest electrical specifications before integration.

Supervisors Selection Notes

Select this part when 16 Kbit EEPROM integration is required with voltage supervision. Ensure 3 V threshold aligns with target supply rail. Verify SOIC-Wide-8 package fits PCB layout. Confirm manual reset meets system control needs. Check if watchdog timer absence is acceptable for application reliability.

Supervisors Part Context

Part of onsemi's CAT1162 series supervisory circuits. Shares family features like EEPROM integration and manual reset. Differs from CAT1163 by lacking watchdog timer. Similar to CAT1024 but with higher EEPROM capacity and wider voltage range. Part of PMIC category focusing on power management ICs.

Supervisors Replacement Considerations

CAT1162WI-30-G offers same specifications in tube packaging. CAT1162WI-28-T3 provides 2.8 V threshold option. CAT1162WI-45-T3 offers 4.5 V threshold variant. All share identical EEPROM and reset features within the CAT1162 family.
