ISL88003IE46Z-T7A

Supervisors Overview

The ISL88003IE46Z-T7A is a voltage supervisory circuit manufactured by Renesas Electronics. It monitors a single input with a threshold of 4.62 V and an overvoltage threshold of 4.681 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 a typical operating current of 400 nA and accuracy of 1.2%. The component is housed in an SC-70-3 package and functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision for single-channel applications
• Features low power consumption suitable for battery-operated systems
• Delivers active high or low reset signals via push-pull output

Supervisors Applications

• Industrial control system monitoring
• Portable electronic device power management
• Embedded system voltage supervision

Supervisors Procurement Notes

Verify the exact suffix T7A against official datasheets to confirm reel packaging specifications. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for obsolescence notices as this series may have discontinuation updates. Ensure the SC-70-3 footprint matches your PCB design constraints.

Supervisors Selection Notes

Select this component when a low-profile SC-70-3 package is required for space-constrained designs. Choose based on the specific 4.62 V threshold requirement for the monitored rail. Consider the 190 ms reset delay for timing-sensitive applications. Evaluate the 400 nA quiescent current against total system power budgets.

Supervisors Part Context

This part belongs to the ISL88003 series of simple reset/voltage supervisor ICs from Renesas. These devices are designed for low-voltage digital circuits requiring reliable power-on reset functionality. The series offers various threshold options packaged in compact surface-mount formats.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the ISL88003 family with different thresholds. Verify if newer Renesas PMIC supervisors offer improved accuracy or lower current consumption.
