CAT1163WI-25-GT3

Supervisors Overview

The CAT1163WI-25-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 16K EEPROM for data storage alongside supervision functions. The device operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 2.5 V with an overvoltage threshold of 2.7 V. Key electrical parameters include a reset delay time of 270 ms, a maximum power dissipation of 1 W, and a quiescent current of 3 mA. It supports manual reset inputs and includes a watchdog timer. The component is housed in an SOIC-8 package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Integrates 16K EEPROM for non-volatile data storage within the supervisory circuit
• Includes a built-in watchdog timer for system reliability monitoring
• Supports manual reset input functionality for user-initiated control
• Provides multiple output types including active high, active low, and open drain configurations

Supervisors Applications

• CPU voltage supervision in embedded systems
• Data retention using integrated EEPROM in microcontroller units
• System reset management with watchdog timer protection

Supervisors Procurement Notes

Verify component authenticity through authorized channels as availability may be limited. Confirm RoHS compliance status and specific lot codes against datasheet requirements. Ensure packaging matches SOIC-8 specifications. Check for obsolescence notices or lifecycle changes from onsemi before finalizing procurement plans.

Supervisors Selection Notes

Select this component when both voltage supervision and 16K EEPROM storage are required in a single package. Compare threshold voltages against target supply rails to ensure proper triggering. Consider the 270 ms reset delay and 3 mA current consumption relative to system power budgets. Verify temperature range compatibility with the intended operating environment.

Supervisors Part Context

This part belongs to the CAT1163 series of supervisory circuits from onsemi. These devices combine voltage monitoring with memory capabilities. The suffix 'G' typically indicates lead-free and halogen-free packaging compliant with RoHS directives. The 'T3' denotes tape and reel packaging format suitable for automated assembly processes.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the CAT1163 family with different threshold voltages. Verify if newer generations from onsemi offer equivalent functionality with updated packaging or enhanced features.
