ISL88706IB831Z

Supervisors Overview

The ISL88706IB831Z is a microprocessor supervisor IC designed to monitor power-supply and battery functions in microprocessor systems. It integrates a watchdog timer, power-fail comparator, manual reset capability, and an adjustable power-on reset circuit. The device operates within a temperature range of -40°C to +85°C and is available in PDIP8 and SOIC8 packages.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a power-fail comparator for voltage supervision
• Features an adjustable power-on reset threshold

Supervisors Applications

• Microprocessor system power supply monitoring
• Battery function supervision in embedded systems
• General-purpose power management circuits

Supervisors Procurement Notes

Verify the exact suffix 'IB831Z' against official Renesas documentation, as standard listings typically reference 'IP831Z'. Confirm current product status, as many devices in this series are marked as Not Recommended for New Designs (NRND). Ensure package type matches design requirements before procurement.

Supervisors Selection Notes

Select this component when a dedicated supervisor with integrated watchdog and adjustable POR is required. Compare against the broader ISL8870x family for specific threshold or package variations. Verify that the operating temperature range and interface requirements align with the target application constraints.

Supervisors Part Context

This part belongs to the ISL8870x series of microprocessor supervisors from Renesas (formerly Intersil). These devices are engineered for high reset threshold accuracy and low power consumption. The series supports various configurations to monitor power supplies and batteries in complex microprocessor environments.

Supervisors Replacement Considerations

Check for direct substitutes within the ISL8870x family, such as the ISL88705, ISL88707, or ISL88708, which share similar functional architectures. Verify pin compatibility and electrical specifications before substituting.
