ISL88001IE31Z-T

Supervisors Overview

The ISL88001IE31Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics. It monitors a single input voltage and provides an active-low push-pull reset output when the supply drops below the threshold. The device operates within a supply voltage range of 1.8 V to 5.5 V, with a typical threshold voltage of 3.07 V (under-voltage: 3.038 V, over-voltage: 3.112 V). It features a fixed reset delay time of 190 ms and high accuracy of 1.2%. The component consumes only 350 nA of operating current and functions reliably across an industrial temperature range from -40°C to +85°C. It is housed in a compact SC-70-3 surface-mount package.

Supervisors Feature Summary

• Provides precise voltage monitoring with 1.2% accuracy for reliable system supervision
• Features ultra-low power consumption of 350 nA to extend battery life in portable devices
• Delivers active-low push-pull reset signals with a fixed 190 ms delay for stable initialization

Supervisors Applications

• Portable electronic devices requiring low standby current

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as this part is marked as end-of-life. Confirm that the SC-70-3 package matches your PCB footprint requirements. Ensure the active-low output polarity aligns with your microcontroller reset pin configuration. Check for moisture sensitivity handling during storage and assembly due to its SMD nature.

Supervisors Selection Notes

Select this component when a single-channel supervisor with active-low output is required. It is suitable for applications where low quiescent current is critical. Consider alternative packages if space constraints differ from SC-70-3. Verify that the 3.07 V threshold meets your specific voltage rail requirements.

Supervisors Part Context

This part belongs to the ISL88001 series of voltage supervisors from Renesas/Intersil. It is designed for general-purpose power management tasks. The series offers various threshold voltages and output types to suit different system needs. This specific variant focuses on low-power operation and compact packaging for modern electronics.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the ISL88001 family with different thresholds. Verify functional equivalence with other active-low supervisors in SC-70-3 packages. Ensure replacement parts maintain similar accuracy and current consumption specs.
