ISL88001IE22Z-TK

Supervisors Overview

The ISL88001IE22Z-TK is a single-channel voltage supervisor IC from Renesas Electronics, designed for ultra-low power applications. It operates within a supply voltage range of 1.6V to 5.5V and features a fixed output threshold of 2.2V. The device consumes only 160nA of quiescent current, making it suitable for battery-powered systems. It utilizes an SC-70-3 package and provides a push-pull or totem-pole output configuration.

Supervisors Feature Summary

• Ultra-low power consumption with 160nA quiescent current
• Fixed voltage monitoring threshold at 2.2V
• Compact SC-70-3 surface-mount packaging

Supervisors Applications

• Battery-operated portable electronics
• Embedded system power management
• Industrial control circuits requiring low standby current

Supervisors Procurement Notes

Verify the specific suffix 'TK' indicates tape-and-reel packaging when ordering. Confirm the 2.2V threshold matches design requirements. Check for recent Product Change Notices regarding datasheet updates or labeling changes. Ensure compatibility with the target PCB footprint for the SC-70-3 package. Validate RoHS compliance status for the specific manufacturing batch.

Supervisors Selection Notes

Select this component when a fixed 2.2V reset threshold is required. Choose based on the need for minimal quiescent current in always-on circuits. Consider the SC-70-3 package size constraints. Compare against adjustable supervisors if variable thresholds are needed. Evaluate total system power budget including the 160nA leakage.

Supervisors Part Context

This part belongs to the ISL88001/2/3 family of voltage supervisors. It serves as a dedicated monitor for single-rail power supplies. The series supports various fixed voltage options for different logic families. It complements Renesas' portfolio of low-power analog monitoring solutions.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives with identical 2.2V thresholds. Verify equivalent quiescent current specifications. Ensure the replacement offers the same SC-70-3 package outline. Confirm output drive capability matches the load requirements.
