ISL88706IB831Z-TK

Supervisors Overview

The ISL88706IB831Z-TK is a microprocessor supervisor integrated circuit manufactured by Renesas Electronics Corporation. It provides essential system protection through a watchdog timer, power-fail comparator, manual reset capability, and an adjustable power-on reset function. The device is designed for monitoring power-supply and battery functions in microprocessor systems, featuring high reset threshold accuracy and low power consumption. It operates within a temperature range of -40°C to 85°C and is available in an 8-pin SOIC package.

Supervisors Feature Summary

• Integrates a watchdog timer and power-fail comparator for comprehensive system monitoring
• Features an adjustable power-on reset threshold for flexible voltage supervision
• Supports manual reset functionality for controlled system initialization

Supervisors Applications

• Microprocessor system power supply monitoring
• Battery function supervision in embedded devices
• Industrial control system reset management

Supervisors Procurement Notes

Verify the exact suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm current production status as legacy Intersil/Renesas parts may have limited availability or obsolescence notices. Ensure compatibility with existing PCB footprints for the 8-pin SOIC package before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with adjustable thresholds and manual reset is required. Compare against the ISL88705, ISL88707, and ISL88708 variants if different reset voltages or package types are needed. Verify that the operating temperature range meets the specific environmental requirements of the target application.

Supervisors Part Context

This part belongs to the ISL887xx series of microprocessor supervisors originally developed by Intersil and now managed by Renesas Electronics. These devices are designed to replace older discrete supervisor solutions, offering integrated watchdog and reset functions in a compact footprint. The series supports various voltage thresholds and package options to suit diverse embedded design needs.

Supervisors Replacement Considerations

Direct pin-compatible alternatives within the same family include ISL88705, ISL88707, and ISL88708, depending on the required reset threshold voltage. Verify if the specific 'B831' trim code matches the desired voltage tolerance in potential substitute parts.
