ISL88003IH46Z-T7A

Supervisors Overview

The ISL88003IH46Z-T7A 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 a push-pull output and provides a reset delay time of 190 ms. It operates within a supply voltage range of 1.8 V to 5.5 V and maintains an accuracy of 1.2%. The component is housed in an SOT-23 package, suitable for surface mount installation, and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single voltage input channel with high precision
• Provides active push-pull reset output signal
• Operates with ultra-low quiescent current consumption
• Includes fixed reset delay timer for stable power-up sequencing

Supervisors Applications

• Portable electronic devices requiring battery voltage monitoring
• Embedded systems needing reliable power-on reset generation
• Industrial control circuits with strict voltage supervision requirements

Supervisors Procurement Notes

Verify the exact suffix and manufacturer documentation before integration, as this component may be discontinued or subject to last-time buy status. Confirm that the SOT-23 package dimensions and pinout match your PCB layout constraints. Ensure compatibility with your system's operating voltage range and thermal environment specifications during the design phase.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with push-pull output is required. It is suitable for applications demanding low standby current and precise threshold detection. Consider the SOT-23 package size for space-constrained designs. Verify that the 190 ms reset delay meets your system's startup timing requirements without external components.

Supervisors Part Context

This part belongs to the ISL88003 series of low-power voltage supervisors from Renesas. The series offers various threshold voltages packaged in compact forms like SC-70-3 and SOT-23. These devices are designed for portable electronics and battery-powered systems where power efficiency and small footprint are critical design parameters.

Supervisors Replacement Considerations

Check for direct cross-references in Renesas' current portfolio. Other ISL88003 variants with different thresholds or packages may serve as functional substitutes if electrical parameters align with your design needs.
