ISL88002IH23Z-T

Supervisors Overview

The ISL88002IH23Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics. It monitors a single input voltage with a threshold of 2.32 V and an accuracy of 1.2%. The device features an active-low, open-drain reset output and 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 350 nA. The component is housed in a SOT-23-3 package and supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable system reset via open-drain output when monitored voltage exceeds specified thresholds
• Optimized for low power consumption suitable for battery-operated applications
• Ensures stable operation through precise voltage monitoring with defined reset timing

Supervisors Applications

• Industrial control systems requiring voltage supervision
• Portable communication devices needing low standby current
• DC/DC and AC/DC converter protection circuits

Supervisors Procurement Notes

Verify the specific suffix IH23Z-T against official Renesas documentation to confirm the exact threshold voltage and package variant. Confirm end-of-life status as discontinuation notices may apply. Ensure compatibility with existing PCB footprint and reflow profiles. Check for moisture sensitivity level requirements during storage and handling. Validate that the open-drain output configuration matches the target system logic levels.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with low quiescent current is required. The 2.32 V threshold suits applications monitoring 3.3 V or similar rails. The SOT-23-3 package offers space efficiency. Consider the 190 ms reset delay for system startup timing constraints. Verify that the open-drain output can drive the necessary load without external pull-up adjustments beyond standard design practices.

Supervisors Part Context

This part belongs to the ISL88002 series of voltage supervisors from Renesas. It is designed for general-purpose power management tasks where precise monitoring is critical. The series includes variants with different thresholds and packages. It complements other PMIC components in complex power trees.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the ISL88002 family with matching thresholds. Verify electrical parameters such as reset delay and operating current against alternative vendors if cross-sourcing. Ensure package dimensions and thermal characteristics remain compatible.
