ISL88001IH17Z-T

Supervisors Overview

The ISL88001IH17Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics. It monitors a single input voltage with a threshold of 1.67 V and an accuracy of 1.2%. The device features a push-pull reset output, a fixed reset delay time of 190 ms, and operates within a supply voltage range of 1.8 V to 5.5 V. It consumes 350 nA of operating current and functions between -40°C and +85°C.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage conditions
• Provides active-low push-pull reset signal generation
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Portable electronic devices requiring battery monitoring
• Embedded systems needing reliable power-on reset sequences
• Industrial control units with strict power management requirements

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Cross-reference datasheet revisions to ensure compatibility with existing design specifications and regulatory compliance standards.

Supervisors Selection Notes

Select this component when precise monitoring of low-voltage rails is required without manual reset functionality. Ensure the 1.67 V threshold aligns with system logic levels. Verify that the 190 ms delay meets timing requirements for downstream microcontroller initialization sequences.

Supervisors Part Context

This part belongs to the ISL88001 series of voltage supervisors designed for low-power applications. It complements Renesas' portfolio of power management integrated circuits by providing essential system protection against unstable power conditions in compact surface-mount packages.

Supervisors Replacement Considerations

ISL88001IE31Z-T offers a 3.07 V threshold variant. ISL88001IE44Z-T provides a 4.38 V threshold option. Both share identical pinouts and functional characteristics suitable for direct substitution if voltage thresholds match system requirements.
