ISL88813IB846Z

Supervisors Overview

The ISL88813IB846Z is a microprocessor supervisor designed for monitoring 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 SOIC-8 packaging.

Supervisors Feature Summary

• Integrates watchdog timer and power-fail comparator for system supervision
• Features adjustable power-on reset threshold voltage
• Supports manual reset functionality

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix IB846Z against official Intersil or Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and reset thresholds before procurement. Cross-reference ordering information directly with manufacturer datasheets to avoid discrepancies in variant identification.

Supervisors Selection Notes

Select this component when a combined solution for power-on reset, watchdog timing, and power-fail detection is required. The adjustable threshold allows customization for various supply voltages. Verify that the SOIC-8 package fits the board layout constraints and that the operating temperature range meets the application environment requirements.

Supervisors Part Context

The ISL88813 belongs to the ISL887xx family of microprocessor supervisors from Intersil (now Renesas). This family includes variants like the ISL88705 through ISL88708 and ISL88716, which share similar core functionalities but differ in specific features such as reset delay times or threshold accuracies. The ISL88813 is specifically noted for its integrated watchdog and manual reset capabilities.

Supervisors Replacement Considerations

Compatible substitutes within the same family include ISL88705, ISL88706, ISL88707, ISL88708, and ISL88716. Verify pinout compatibility and specific feature sets, such as watchdog timeout periods and reset threshold adjustments, before substituting.
