ISL88001IH46Z-T

Supervisors Overview

The ISL88001IH46Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input voltage with a threshold of 4.38 V and an overvoltage threshold of 4.433 V. The device features a push-pull output, a reset delay time of 190 ms, and operates within a supply voltage range of 1.8 V to 5.5 V. It has an accuracy of 1.2% and consumes 400 nA of quiescent current. The component is housed in an SC-70-3 package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single power rail for under-voltage and over-voltage conditions
• Provides active-low reset signal via push-pull output
• Operates with ultra-low quiescent current consumption
• Ensures precise voltage monitoring with high accuracy

Supervisors Applications

• Portable electronic devices requiring battery voltage supervision
• Embedded systems needing reliable power-on reset generation
• Industrial control units monitoring critical logic supply rails

Supervisors Procurement Notes

Verify the specific suffix 'IH46' against official Renesas documentation to confirm the exact threshold voltage and package variant, as datasheets may list similar part numbers with different electrical characteristics. Confirm end-of-life status and availability through authorized distributors, as this component may be discontinued or subject to limited stock constraints.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with low power consumption is required. Ensure the monitored voltage aligns with the 4.38 V threshold. Consider the SC-70-3 package size for space-constrained designs. Verify that the 190 ms reset delay meets system timing requirements during power-up sequences.

Supervisors Part Context

This part belongs to the ISL8800x series of low-power voltage supervisors from Renesas (formerly Intersil). These components are designed for applications where power efficiency and compact footprint are critical. The series typically offers various threshold options and package types to suit different monitoring needs in portable and industrial electronics.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the ISL8800x family with matching thresholds. Verify compatibility with alternative manufacturers offering similar SC-70-3 voltage supervisors, ensuring identical electrical parameters and reset functionality.
