ISL88708IB826Z

Supervisors Overview

The ISL88708IB826Z is a single-channel power supply supervisor manufactured by Renesas Electronics Corporation, formerly Intersil. It operates within a supply voltage range of 2 V to 5.5 V and features a threshold voltage of 2.63 V. The device provides manual reset, watchdog timer, and adjustable power-on reset functions with a minimum reset timeout of 140 ms. It supports both high-active and low-active reset outputs in open-drain or push-pull configurations. The component is housed in an 8-SOIC package (0.154 inch width) and is designed for surface-mount installation. It functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates manual reset input, watchdog timer, and adjustable power-on reset functionality within a single channel.
• Offers flexible output drive capabilities with selectable open-drain or push-pull reset modes.
• Supports configurable active-high or active-low reset signal polarity for system integration.

Supervisors Applications

• Industrial control systems requiring reliable power supervision
• Embedded processor reset management circuits
• Portable equipment power monitoring

Supervisors Procurement Notes

Verify component status as the ISL88708IB826Z is listed as obsolete or end-of-life in distributor records. Confirm availability through alternate manufacturing sites or authorized distributors. Check for RoHS compliance status and ensure compatibility with current environmental regulations before procurement planning.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and manual reset is required. Ensure the 2.63 V threshold aligns with the monitored rail voltage. Verify that the 8-SOIC package fits the PCB layout constraints and that the operating temperature range meets the application environment requirements.
