CAT1163WI-30TE13

Supervisors Overview

The CAT1163WI-30TE13 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 16K EEPROM with the supervisor functionality. The device operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 3 V with an overvoltage threshold of 3.15 V. It provides active high, active low, and open drain output options, along with manual reset capability and a watchdog timer. The reset delay time is specified at 270 ms, and the quiescent current is 3 mA. It is housed in an SOIC-Wide-8 package and supports industrial temperature ranges from -40°C to +85°C.

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices since this part may be discontinued. Ensure packaging specifications match project requirements. Validate electrical parameters against the latest datasheet revisions before integration.

Supervisors Selection Notes

Select this component when combined voltage supervision and data storage are required in a single package. Consider the specific threshold voltage requirements relative to the monitored rail. Evaluate the need for manual reset and watchdog features. Verify package compatibility with PCB layout constraints. Assess operating temperature range suitability for the target environment.

Supervisors Part Context

This part belongs to the CAT1163 series of supervisory circuits from onsemi. The series typically combines voltage monitoring with EEPROM capabilities. Variants differ primarily in threshold voltages and packaging options. The WI suffix indicates a wide-body SOIC package. The TE13 suffix denotes tape and reel packaging configuration.

Supervisors Replacement Considerations

Check for CAT1163WI-30-GT3 or CAT1163WI-30-T3 as potential pin-compatible alternatives within the same family. Verify functional equivalence regarding EEPROM size and supervisor features. Confirm package dimensions and pinout compatibility before substitution.
