ISL88002IH31Z-T7A

Supervisors Overview

The ISL88002IH31Z-T7A is a low-power voltage supervisor integrated circuit manufactured by Renesas Electronics Corporation. It monitors a single input voltage with a threshold of 3.09V and features an active-low, open-drain reset output. The device operates within a supply voltage range of 1.8V to 5.5V and maintains a typical operating current of 350nA. It provides a minimum reset timeout of 140ms and functions reliably across a temperature range of -40°C to +85°C. The component is housed in a compact SC-70 (SOT-323) surface-mount package.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage conditions
• Provides an active-low open-drain reset signal upon fault detection
• Operates with ultra-low quiescent current consumption
• Ensures system stability with a guaranteed minimum reset delay

Supervisors Applications

• Portable battery-powered electronic devices
• Industrial control systems requiring voltage supervision
• Embedded microcontroller reset circuits
• Consumer electronics power management

Supervisors Procurement Notes

Verify the specific suffix 'T7A' corresponds to the SC-70-3 package configuration. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Check for End-of-Life notices or Product Change Notifications regarding label updates or discontinuation schedules before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a simple, low-cost voltage monitor is required for a single rail. Ensure the 3.09V threshold aligns with the monitored supply level. Verify that the open-drain output interface is compatible with the downstream logic inputs. Consider the SC-70 footprint constraints during PCB layout design.

Supervisors Part Context

This part belongs to the ISL88002 series of low-power voltage supervisors from Renesas. The series offers various threshold voltages and package options to suit different monitoring needs. The ISL88002 variant specifically targets applications requiring minimal standby current and a compact form factor for space-constrained designs.

Supervisors Replacement Considerations

ISL88002IE17Z-T7A: Different threshold voltage (1.67V). ISL88002IE23Z-T7A: Different threshold voltage (2.32V). ISL88002IH23Z-T: Different package (SOT-23-3). Verify threshold and package compatibility for direct substitution.
