ISL88002IH46Z-T

Supervisors Overview

The ISL88002IH46Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics. It monitors a single input voltage with a threshold of 4.62 V and an overvoltage threshold of 4.681 V. The device features an active-low, open-drain reset output and provides a fixed reset delay time of 190 ms. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical operating current of 325 nA. Accuracy is specified at 1.2%. The component is housed in an SOT-23-3 package and supports surface-mount installation.

Supervisors Feature Summary

• Provides precise voltage monitoring with high accuracy for system reliability
• Features ultra-low power consumption suitable for battery-operated applications
• Includes a fixed reset delay to ensure stable power-up sequencing

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing voltage supervision
• Embedded circuits utilizing low-voltage logic interfaces

Supervisors Procurement Notes

Verify the specific suffix IH46 against official datasheets to confirm the 4.62 V threshold variant. Confirm RoHS compliance status and moisture sensitivity level requirements before ordering. Check for end-of-life notices as availability may be limited. Ensure the SOT-23-3 package footprint matches your PCB design constraints.

Supervisors Selection Notes

Select this component when a single-channel supervisor with open-drain output is required. Compare the 4.62 V threshold against system voltage rails to ensure proper triggering. Consider the 190 ms delay for timing-sensitive applications. Verify that the 325 nA quiescent current meets strict power budget requirements.

Supervisors Part Context

This part belongs to the ISL88002 series of low-power voltage supervisors from Renesas. The series offers various threshold options packaged in compact SOT-23 form factors. These components are designed for portable electronics where space and power efficiency are critical constraints.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the ISL88002 family with different thresholds. Verify if newer Renesas supervisory ICs offer improved accuracy or lower current consumption while maintaining the same package.
