X4163PIZ-4.5A

Supervisors Overview

The X4163PIZ-4.5A is a single-channel supervisor IC manufactured by Renesas Electronics Corporation, designed for simple reset and power-on reset applications. It features an open drain or open collector output with active low reset signaling. The device monitors one voltage threshold set at 4.62V and provides a minimum reset timeout of 100ms. Packaged in an 8-DIP (7.62mm) through-hole format, it operates within a temperature range of -40°C to 85°C. This component is currently obsolete and no longer in production.

Supervisors Feature Summary

• Provides hardware-based system reset functionality triggered by power supply anomalies
• Features open drain/open collector output compatible with various logic families
• Ensures stable operation with a fixed minimum reset delay period

Supervisors Applications

• Microcontroller system supervision
• Embedded controller power monitoring
• Digital circuit reset management

Supervisors Procurement Notes

Verify component authenticity as the X4163PIZ-4.5A is officially obsolete. Confirm that available units are genuine Renesas products rather than refurbished items. Check datasheet revisions for any historical manufacturing changes. Ensure compatibility with existing PCB footprints before procurement. Validate supplier authorization status due to discontinued status.

Supervisors Selection Notes

Consider the fixed 4.62V threshold when evaluating suitability for specific supply rails. Assess whether the 100ms minimum timeout meets system startup requirements. Verify that the 8-DIP package aligns with assembly capabilities. Evaluate alternative supervisors if new design constraints require adjustable thresholds or different output configurations.
