ISL88011IH529Z-TK

Supervisors Overview

The ISL88011IH529Z-TK is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It operates within a supply voltage range and monitors one input channel with a threshold of 2.92V. The device provides reset outputs in both open-drain and push-pull configurations, supporting active-high or active-low logic levels. It features a minimum reset timeout of 140ms to ensure stable power-up sequences. Designed for surface-mount installation in SC-74A (SOT-753) packages, it functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for single voltage monitoring applications
• Offers flexible output drive options including open-drain and push-pull configurations
• Supports configurable active-high or active-low reset signal polarity

Supervisors Applications

• Industrial control systems requiring reliable power supervision
• Embedded systems needing stable power-on reset sequencing
• Consumer electronics utilizing single-voltage rail monitoring

Supervisors Procurement Notes

This component is officially classified as obsolete by the manufacturer. Procurement should focus on verifying authenticity through authorized channels due to potential availability from surplus markets. Buyers must confirm the specific revision level and packaging type matches their design requirements, as legacy stock may vary in condition. Cross-referencing with current replacement families is recommended for new designs.

Supervisors Selection Notes

Select this part when a single-channel supervisor with adjustable power-on reset timing is required. It is suitable for designs needing both open-drain and push-pull output flexibility. Verify that the 2.92V threshold aligns with the monitored rail voltage. Ensure the SC-74A package fits the PCB footprint constraints. Consider the operating temperature range suitability for the intended environment.

Supervisors Part Context

The ISL88011 belongs to the ISL8801x series of 5-lead voltage supervisors from Renesas. This family includes variants like the ISL88013 and ISL88015, offering similar core functionalities with differing thresholds or features. These devices are designed for compact space-constrained applications requiring robust power management supervision in industrial and commercial environments.

Supervisors Replacement Considerations

Direct substitutes include other parts from the ISL8801x series such as the ISL88013IH529Z-TK. Verify pin compatibility and electrical specifications before substitution. Check for updated manufacturing status as original parts are obsolete.
