ISL88002IH46Z-TK

Supervisors Overview

The ISL88002IH46Z-TK is a low-power voltage supervisor manufactured by Renesas Electronics. It operates within a supply voltage range of 1.8 V to 5.5 V and features a fixed threshold voltage of 4.62 V. The device provides an active-low open-drain reset output with a typical reset delay time of 190 ms. It is housed in a SOT-23-3 package, consumes 350 nA of operating current, and maintains an accuracy of 1.2%. The component functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides precise voltage monitoring for single-input systems
• Generates active-low reset signal upon undervoltage conditions
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Portable electronic devices requiring battery protection
• Embedded systems needing brown-out detection
• Industrial control circuits monitoring power rails

Supervisors Procurement Notes

Verify the specific suffix IH46Z-TK to confirm the SOT-23-3 package and 4.62 V threshold. Confirm RoHS compliance status as per the latest datasheet revision. Check for End-of-Life notices, as previous variants indicate potential obsolescence. Ensure compatibility with existing PCB footprints for SOT-23-3 components during sourcing.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for system supervision. The SOT-23-3 package suits space-constrained designs. Verify that the 190 ms reset delay meets system timing requirements. Consider the 1.2% accuracy tolerance for critical voltage monitoring applications. Ensure the open-drain output interface aligns with the downstream logic levels.

Supervisors Part Context

This part belongs to the ISL88002 series of ultra-low power voltage supervisors. The series includes variants with different thresholds and packages. The ISL88002 family is designed for portable and battery-operated equipment. It offers reliable performance in harsh environments with specified temperature ranges.

Supervisors Replacement Considerations

ISL88002IE46Z-T is a pin-compatible alternative in SC-70-3 package. ISL88002IH26Z-TK shares the same package but has a 2.63 V threshold. Verify electrical parameters before substitution.
