ISL88708IB844Z

Supervisors Overview

The ISL88708IB844Z is a single-channel microprocessor supervisor integrated 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 an adjustable power-on reset threshold and includes a watchdog timer, power-fail comparator, manual reset input, and adjustable trip point functionality. It is housed in an 8-lead Small Outline Integrated Circuit (SOIC) package with a width of 3.90 mm. The component supports surface-mount installation and provides push-pull or open-drain outputs. It is designed for industrial applications with an operating temperature range spanning from -40°C to +85°C.

Supervisors Feature Summary

• Integrates watchdog timer, power-fail comparator, and manual reset capabilities for comprehensive system monitoring.
• Features adjustable power-on reset thresholds and trip points to accommodate various voltage levels.
• Supports both push-pull and open-drain output configurations for flexible interface compatibility.

Supervisors Applications

• Industrial control systems requiring reliable power supervision
• Embedded systems needing watchdog timer protection
• Microprocessor-based designs with manual reset requirements

Supervisors Procurement Notes

Verify the specific suffix IB844Z against the official datasheet to confirm the exact threshold voltage and output configuration. Confirm that the component status aligns with project lifecycle requirements, as availability may vary. Ensure the SOIC-8 package dimensions match the PCB footprint specifications. Check RoHS compliance documentation if environmental regulations apply to the final assembly. Validate the operating temperature range against the intended application environment.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and manual reset functions is required. The adjustable threshold allows customization for different supply voltages within the 2 V to 5.5 V range. Consider the SOIC-8 package size for space-constrained designs. Evaluate the need for push-pull versus open-drain outputs based on downstream logic requirements. Ensure the industrial temperature range meets the operational conditions.

Supervisors Part Context
