X5163S8

Supervisors Overview

The X5163S8Z-4.5A is a voltage supervisory circuit manufactured by Renesas Electronics, designed for monitoring single input voltages within a range of 4.5 V to 5.5 V. It features an active high output and includes a built-in watchdog timer with a reset delay time of 280 ms. The device operates on a supply voltage up to 5.5 V, with a typical operating current of 5 mA. It provides overvoltage detection at 4.75 V and undervoltage detection at 4.5 V. The component is housed in an SOIC-8 package, measuring 5 mm in length, 4 mm in width, and 1.5 mm in height. It supports surface mount installation and functions reliably across temperatures from 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability
• Provides active high reset output signal
• Detects both overvoltage and undervoltage conditions

Supervisors Applications

• CPU supervision in embedded systems
• Watchdog timer implementation
• SPI EEPROM reset management

Supervisors Procurement Notes

Verify the specific suffix (e.g., Z-4.5A) against official Renesas documentation to confirm threshold voltage accuracy and package type. Ensure compatibility with the target system's voltage range and temperature requirements. Confirm RoHS compliance status as indicated in the latest datasheet. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with integrated watchdog functionality is required for 5V logic systems. Consider the active high output polarity and the fixed reset delay time. Evaluate the thermal performance within the specified operating temperature range. Compare against other series members if different threshold voltages or manual reset capabilities are needed.

Supervisors Part Context

The X5163 series belongs to Renesas' family of voltage supervisory circuits. These components are designed to monitor power supply integrity and provide reset signals to microprocessors and memory devices. The series typically offers various threshold options and packaging configurations to suit different application needs.

Supervisors Replacement Considerations

Consult official substitution guides for equivalent parts with matching threshold voltages and package dimensions. Verify functional compatibility regarding watchdog timer operation and output drive capability.
