X4163S8I-4.5A

Supervisors Overview

The X4163S8I-4.5A is a power management supervisor integrated circuit manufactured by Renesas Electronics Corporation. It operates within an ambient temperature range of -40°C to +85°C and utilizes an 8-SOIC surface-mount package with dimensions of 3.90mm width. The device features a voltage threshold of 4.62V and provides an active-low reset output. Designed for monitoring system voltages, it supports open-drain or open-collector configurations to ensure reliable reset control in electronic applications requiring precise voltage supervision.

Supervisors Feature Summary

• Provides system voltage monitoring and reset control functionality
• Features an active-low reset output signal
• Supports open-drain or open-collector output configurations

Supervisors Applications

• Monitoring system voltage in electronic devices
• Providing reset control for microprocessor systems
• Supervising battery-powered equipment operating near 4.8V

Supervisors Procurement Notes

Verify the specific suffix '4.5A' corresponds to the required 4.62V threshold and active-low output configuration. Confirm the 8-SOIC package variant matches your PCB footprint requirements. Ensure compatibility with the target operating temperature range of -40°C to +85°C for your specific application environment before finalizing procurement.

Supervisors Selection Notes

Select this component when a dedicated supervisor IC is needed for voltage monitoring with a fixed threshold around 4.62V. It is suitable for designs requiring an active-low reset signal with open-drain flexibility. Consider the 8-SOIC package size constraints and the specified industrial temperature range during the initial hardware architecture phase.

Supervisors Part Context

This part belongs to the Renesas power management supervisor family, designed to enhance system reliability by detecting under-voltage conditions. Unlike general-purpose logic, it specifically manages reset states based on monitored supply rails. The X4163 series typically integrates precision comparators and timers to prevent erratic behavior during power-up or brown-out events.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and threshold voltage compatibility if considering alternative supervisors from other manufacturers.
