ISL88002IE31Z-T7A

Supervisors Overview

The ISL88002IE31Z-T7A is a single-channel voltage supervisor IC manufactured by Renesas Electronics Corporation. It features an active low reset output with open drain or open collector configuration, housed in a SC-70 (SOT-323) surface-mount package. The device monitors a single input voltage with a threshold of 3.09V and provides a minimum reset timeout of 140ms. It operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored power supplies
• Features an active low reset signal with open drain/open collector output capability
• Designed for low power voltage supervision applications

Supervisors Applications

• Monitoring +3.0V power supplies in industrial control systems
• Voltage supervision for embedded processing circuits
• Power management in portable electronic devices

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm package marking and date codes against current manufacturing records. Check for product change notices affecting datasheet specifications or labeling. Ensure compatibility with existing board layouts given the SC-70-3 footprint. Validate supply chain sources to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 3.09V threshold is required for single-rail monitoring. Consider the open-drain output for flexible logic level interfacing. Evaluate the 140ms minimum timeout against system startup requirements. Compare pinout and thermal characteristics with alternative supervisors in the same package family.

Supervisors Part Context

This part belongs to the ISL88002 series of single-channel voltage supervisors from Renesas. The series offers various fixed voltage thresholds to monitor standard logic levels such as 1.8V, 2.5V, 3.0V, 3.3V, and 5.0V. The IE31 suffix indicates the specific 3.09V threshold variant within this product line.

Supervisors Replacement Considerations

ISL88002IE17Z-T7A: Different threshold voltage (1.67V). ISL88003IH31Z-T7A: Different package (SOT-23) and push-pull output.
