ISL88706IP844Z

Supervisors Overview

The ISL88706IP844Z is a microprocessor supervisor circuit manufactured by Intersil, now part of Renesas Electronics. It provides essential power management functions including a watchdog timer, power-fail comparator, manual reset capability, and an adjustable power-on reset. The device operates within a supply voltage range of 2 V to 5.5 V and is rated for an industrial temperature range of -40°C to +85°C. It is housed in an 8-pin PDIP or SOIC package with dual gull-wing terminals spaced at 1.27 mm.

Supervisors Feature Summary

• Integrates a watchdog timer and power-fail comparator for system reliability
• Features an adjustable power-on reset threshold for flexible configuration
• Includes manual reset functionality for user-initiated system control

Supervisors Applications

• Microprocessor system power monitoring
• Battery function supervision
• Industrial control systems requiring reset management

Supervisors Procurement Notes

Verify the specific suffix IP844Z against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote specific package variants or testing levels. Confirm current production status and availability through authorized distributors, as Intersil products are managed under the Renesas portfolio.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and manual reset is required. Ensure the adjustable reset threshold meets the specific voltage monitoring needs of the target microprocessor. Verify that the operating temperature range and package type align with the design constraints.

Supervisors Part Context

This device belongs to the ISL8870x series of microprocessor supervisors, which also includes models like the ISL88705, ISL88707, and ISL88708. These devices are designed for high reset threshold accuracy and low power consumption, serving as a family of solutions for monitoring power-supply and battery functions in various electronic systems.

Supervisors Replacement Considerations

Consult Renesas Product Legacy Documents for confirmed substitutes. Cross-reference with other members of the ISL8870x series if functional differences in reset thresholds or package types are acceptable.
