ISL88708IB826Z

Supervisors Overview

The ISL88708IB826Z is a single-channel power supply management circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2 V to 5.5 V, with a rated voltage of 5 V. The device features a threshold voltage of 2.63 V and provides a minimum reset timeout of 140 ms. It supports both high-active and low-active reset outputs in an open-drain or push-pull configuration. The component is housed in an 8-SOIC surface-mount package with a width of 3.90 mm and functions across a temperature range of -40°C to 85°C.

Supervisors Feature Summary

• Integrates simple reset and power-on reset functionality for single-channel monitoring
• Offers configurable active-high or active-low reset signal polarity
• Supports open-drain or push-pull output drive configurations

Supervisors Applications

• Industrial control systems requiring power supervision
• Embedded systems needing reliable power-on reset generation
• General-purpose microcontroller power management circuits

Supervisors Procurement Notes

Verify component status as the specific part number ISL88708IB826Z is listed as obsolete by the manufacturer. Confirm availability through authorized distributors for remaining stock or evaluate alternative packages within the ISL88708 family that remain active. Ensure compliance with RoHS3 specifications and check for any recent product change notices regarding manufacturing sites or labeling updates before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a fixed 2.63 V threshold is required. Consider the 140 ms minimum reset timeout for system stability requirements. Choose between open-drain and push-pull outputs based on interface compatibility. Verify that the operating voltage range of 2 V to 5.5 V aligns with the monitored rail. The 8-SOIC package is suitable for standard surface-mount assembly processes.

Supervisors Part Context

The ISL88708 belongs to a family of µP supervisors from Renesas (formerly Intersil) designed for power supply management. Variants such as ISL88708IP844Z include additional features like watchdog timers and manual reset inputs. The IB suffix denotes the SOIC package variant, while IP indicates PDIP packaging. This series addresses basic reset needs in industrial and consumer electronics applications.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ISL88708IB826Z-TK, ISL88708IB829Z, ISL88708IB829Z-TK, ISL88708IB831Z, ISL88708IB831Z-TK, ISL88708IB844Z-TK, ISL88708IP826Z, and ISL88708IP831Z. Evaluate these alternatives for package compatibility and functional equivalence.
