ISL88813IP846Z

Supervisors Overview

The ISL88813IP846Z is a microprocessor supervisor integrated circuit manufactured by Renesas Electronics Corporation. It features a watchdog timer, power-fail comparator, manual reset capability, and adjustable power-on reset. The device operates within an input voltage range of 2V to 5.5V with a threshold of 4.64V. It is housed in an 8-DIP package (0.300 inch width) designed for through-hole mounting. The component supports high and low active reset outputs and functions across a temperature range of -40°C to 85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring
• Includes a power-fail comparator for voltage supervision
• Provides manual reset functionality alongside automatic power-on reset

Supervisors Applications

• Microprocessor system supervision
• Industrial control systems
• Embedded computing platforms

Supervisors Procurement Notes

Verify the specific suffix IP846Z to confirm the 8-DIP through-hole package variant. Confirm RoHS compliance status as per current manufacturer documentation. Check for end-of-life notices or obsolescence alerts prior to procurement planning. Ensure compatibility with existing board layouts for through-hole assembly processes.

Supervisors Selection Notes

Select this component when through-hole mounting is required for supervisor circuits. Choose based on the 4.64V threshold requirement and the need for combined watchdog and power-fail monitoring. Consider the 2V to 5.5V operating range for compatibility with standard logic levels. Evaluate the 8-DIP package constraints against available PCB space.

Supervisors Part Context

This part belongs to the ISL887xx/ISL888xx series of microprocessor supervisors from Renesas. These devices are designed to provide essential protection for digital systems by asserting reset signals during power-up, power-down, and brownout conditions. The series typically includes variants with different packages and feature sets such as watchdog timers and adjustable thresholds.
