ISL88003IE46Z-TK

Supervisors Overview

The ISL88003IE46Z-TK 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, operates within a supply voltage range of 1.8 V to 5.5 V, and provides a reset delay time of 190 ms. It has a typical accuracy of 1.2% and consumes 400 nA of operating current. The component is housed in an SC-70-3 package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage and over-voltage conditions
• Provides active-low or active-high reset signals via a push-pull output stage
• Operates with ultra-low quiescent current consumption
• Includes a fixed internal reset delay timer

Supervisors Applications

• Portable electronic devices requiring low-power monitoring
• Battery-operated systems needing voltage supervision
• Embedded control circuits with limited board space
• Industrial equipment operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status through the manufacturer's datasheet. Check for obsolescence notices as this part may be discontinued. Ensure the SC-70-3 package matches your PCB footprint requirements before procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with low quiescent current is required. The 4.62 V threshold suits applications monitoring 5 V rails. Consider the SC-70-3 package size for space-constrained designs. Verify that the 190 ms reset delay meets system timing requirements. Compare with similar parts if manual reset functionality is needed.

Supervisors Part Context

This component belongs to the ISL88003 series of voltage supervisors from Renesas. These devices are designed for low-power applications where precise voltage monitoring is critical. The series offers various threshold voltages to accommodate different supply rails. The ISL88003IE46Z-TK specifically targets the 4.62 V threshold requirement within this family.

Supervisors Replacement Considerations

Check for direct pin-compatible replacements with identical thresholds. Verify that alternative components offer similar quiescent current and reset delay times. Ensure the replacement supports the same operating temperature range and package type.
