ISL88001IE31Z-TK

Supervisors Overview

The ISL88001IE31Z-TK is a low-power voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input voltage with a threshold of 3.07 V, featuring undervoltage and overvoltage thresholds at 3.038 V and 3.112 V respectively. The device provides an active low push-pull reset output with a typical delay of 190 ms. Operating from 1.8 V to 5.5 V, it consumes 350 nA in SC-70-3 packaging.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage and over-voltage conditions
• Provides an active low push-pull reset signal upon fault detection
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Industrial control systems requiring power monitoring
• Portable electronic devices needing low standby current
• Embedded systems utilizing microcontroller supervision

Supervisors Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging details, as datasheets may list 'T' or other variants. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices as related ISL88001 models have faced obsolescence warnings.

Supervisors Selection Notes

Select this component when a single-channel supervisor with push-pull output is required. Ensure the 3.07 V threshold aligns with the target system voltage. Verify that the SC-70-3 package fits the design constraints. Consider the 190 ms reset delay for timing requirements.

Supervisors Part Context

This part belongs to the ISL88001 series of simple reset circuits. It is designed for applications where low power consumption and small footprint are critical. The series includes variants with different thresholds and output types, such as open-drain configurations.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the ISL88001 family with adjusted thresholds. Verify if newer Renesas PMIC families offer integrated solutions. Cross-reference with Intersil legacy parts if sourcing from secondary markets.
