ISL88813IB846Z-TK

Supervisors Overview

The ISL88813IB846Z-TK is a single-channel voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.0V to 5.5V and features an adjustable reset threshold voltage with a typical accuracy of 1%. The device provides both open-drain and push-pull output configurations, supporting active-high or active-low reset signals. It includes a programmable reset timeout period ranging from 1ms to 1.4s. The component is designed for surface-mount installation in an 8-SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-output architecture providing both open-drain and push-pull reset signals for flexible system integration
• Adjustable reset threshold voltage allows precise monitoring of various power rail levels
• Configurable reset timeout duration supports specific startup sequence requirements
• Supports active-high or active-low logic states for compatibility with diverse microcontroller inputs

Supervisors Applications

• Industrial control systems requiring reliable power supervision

• Telecommunications equipment utilizing multi-voltage power architectures

Supervisors Procurement Notes

Verify the exact suffix configuration against official Renesas documentation to ensure correct output type and timeout settings. Confirm RoHS compliance status and lead-free manufacturing details prior to procurement. Check for end-of-life notices or obsolescence warnings as this component may have limited availability. Ensure the selected package variant matches the PCB footprint requirements. Validate thermal performance specifications against the intended operating environment.

Supervisors Selection Notes

Select this component when a single-channel supervisor with dual output types is required. Consider the adjustable threshold if standard fixed voltages do not match the monitored rail. Evaluate the reset timeout range against the system's maximum startup time. Verify that the SOIC package dimensions fit the design constraints. Compare power consumption characteristics against other supervisors if low standby current is critical.

Supervisors Part Context

This part belongs to the ISL8870x family of voltage supervisors, which includes similar devices like the ISL88708 and ISL88716. These components share common architectural features such as adjustable thresholds and multiple output options. The family is designed for general-purpose power management applications where reliable reset generation is essential. Variants within the family differ primarily in package types, specific threshold ranges, and output configurations.

Supervisors Replacement Considerations

Direct replacements include the ISL88708IB844Z and ISL88716IB846Z. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Ensure the replacement device meets the same temperature and voltage specifications. Review datasheet differences for any changes in reset timeout behavior or output drive strength.
