ISL88708IP826Z

Supervisors Overview

The ISL88708IP826Z is a single-channel microprocessor supervisor circuit manufactured by Intersil, now part of Renesas Electronics. It operates within a supply voltage range of 2 V to 5.5 V, with a rated voltage of 5 V. The device features an adjustable power-on reset threshold set at 2.63 V and provides 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-pin SOIC package with a 1.27 mm lead pitch and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates manual reset input capability for system control
• Includes watchdog timer functionality for fault detection
• Features power-fail comparator for voltage monitoring

Supervisors Applications

• Microprocessor system power supervision
• Industrial control unit reset management
• Battery-powered device power monitoring

Supervisors Procurement Notes

Verify the specific suffix IP826Z against current Renesas documentation, as availability may vary due to product lifecycle status. Confirm that the package type matches the required PCB footprint and that the operating temperature range meets environmental specifications. Cross-reference the threshold voltage setting with design requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with adjustable thresholds and integrated watchdog features is required. Ensure the 8-SOIC package fits the board layout constraints. Verify compatibility with the system's logic levels for the reset output configuration. Consider the thermal performance within the specified -40°C to +85°C range for the intended application environment.

Supervisors Part Context

This device belongs to the ISL8870x family of microprocessor supervisors, which includes variants like the ISL88705, ISL88706, and ISL88707. These components share similar architectures but differ in threshold voltages and package options. The ISL88708 series is designed for applications requiring reliable power management and reset generation in embedded systems.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the ISL8870x family, such as ISL88708IB826Z, ensuring identical threshold and package specifications. Verify functional equivalence regarding watchdog and manual reset features before substitution.
