ISL88012IH526Z

Supervisors Overview

The ISL88012IH526Z is a dual-channel voltage supervisor IC from the Intersil family, designed for power supply monitoring. It features an open-drain reset output and a push-pull alarm output. The device monitors two independent voltage inputs with a threshold of 2.63 V. It operates within a supply voltage range of 1.8 V to 5.5 V and maintains high accuracy of 1.2%. The component includes a fixed reset delay time of 190 ms and consumes a low operating current of 350 nA. It is housed in a compact SOT-23-5 package suitable for surface-mount applications.

Supervisors Feature Summary

• Dual-channel supervision capability for monitoring multiple power rails simultaneously
• Combined open-drain reset and push-pull alarm outputs for flexible system integration
• Ultra-low quiescent current consumption for energy-efficient operation

Supervisors Applications

• Portable electronic devices requiring multi-voltage monitoring
• Embedded systems with strict power management requirements
• Industrial control units needing reliable voltage supervision

Supervisors Procurement Notes

Verify the specific suffix 'H' indicates the SOT-23-5 package configuration and '526' denotes the 2.63 V threshold setting. Confirm RoHS compliance status through official Renesas documentation. Check for end-of-life notices as Intersil products may have transitioned manufacturing statuses. Ensure compatibility with your board's thermal and electrical specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when dual-channel monitoring is required with distinct reset and alarm signaling capabilities. The low operating current makes it suitable for battery-powered applications. Verify that the 2.63 V threshold aligns with your system's critical voltage levels. Consider the SOT-23-5 footprint constraints during PCB layout design to ensure proper mounting and thermal performance.

Supervisors Part Context

This part belongs to the ISL880xx series of voltage supervisors manufactured by Intersil, now part of Renesas Electronics. These components are designed for power management integrated circuits (PMIC) applications. The series offers various threshold options and package configurations to suit different monitoring needs in consumer and industrial electronics markets.

Supervisors Replacement Considerations

Check for direct substitutes within the ISL880xx series with matching thresholds and packages. Verify pinout compatibility if replacing with similar dual-channel supervisors from other manufacturers. Ensure equivalent electrical characteristics such as reset delay and accuracy are maintained for system stability.
