ISL88706IB826Z

Supervisors Overview

The ISL88706IB826Z is a microprocessor supervisor integrated circuit manufactured by Renesas Electronics Corporation. It provides monitoring for power-supply and battery functions in microprocessor systems, featuring adjustable power-on reset, manual reset, watchdog timer, and power-fail comparator capabilities. The device operates within a supply voltage range up to 5.5V and supports a threshold voltage of 3.09V. It offers open-drain and push-pull outputs with high reset threshold accuracy and low power consumption. The component is housed in an 8-SOIC package (0.154 inch width) and is designed for surface-mount installation. It functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates multiple supervision functions including adjustable power-on reset, manual reset, watchdog timer, and power-fail comparator within a single channel.
• Provides flexible output configurations with both open-drain and push-pull options to accommodate various system logic requirements.
• Designed with high reset threshold accuracy and low power consumption to ensure reliable monitoring of power-supply and battery functions.

Supervisors Applications

• Microprocessor system power management
• Industrial controls

Supervisors Procurement Notes

Verify the specific suffix IB826Z against official Renesas documentation to confirm pinout and electrical characteristics match your design requirements. Note that this product status is listed as obsolete or discontinued in public distributor records; confirm availability through authorized channels or consider alternative sourcing strategies if current production units are required for manufacturing.

Supervisors Selection Notes

Select this component when a single-channel supervisor with combined watchdog and power-fail features is needed. Ensure the 3.09V threshold aligns with your system's voltage rails. The 8-SOIC package suits standard surface-mount assembly processes. Verify compatibility with the target microprocessor's reset signal polarity and timing requirements before finalizing the design.

Supervisors Part Context

The ISL88706 belongs to the ISL8870x family of microprocessor supervisors, which includes models like the ISL88705, ISL88707, and ISL88708. These devices share common design goals of providing robust system reset management with low power consumption. The ISL88706 specifically distinguishes itself by offering adjustable thresholds and integrated watchdog functionality, making it suitable for complex embedded applications requiring comprehensive power monitoring.

Supervisors Replacement Considerations

Public records indicate the ISL88706 series is obsolete. Check for direct replacements within the Renesas portfolio such as the ISL88705 or ISL88707 if pin-compatible alternatives are available. Verify functional equivalence regarding threshold voltages and output types before substitution.
