ISL88001IH26Z-T

Supervisors Overview

The ISL88001IH26Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics. It monitors a single input voltage within a supply range of 1.8 V to 5.5 V. The device features a threshold voltage of 2.63 V, with specific under-voltage and over-voltage thresholds at 2.598 V and 2.662 V respectively. It provides an open-drain reset output with a fixed delay time of 190 ms. The component operates in temperatures from -40°C to +85°C, consumes 350 nA of quiescent current, and maintains an accuracy of 1.2%. It is housed in an SOT-23 package.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage and over-voltage conditions
• Provides an active-low open-drain reset signal upon fault detection
• Operates with ultra-low quiescent current consumption suitable for battery-powered systems

Supervisors Applications

• Portable electronic devices requiring low standby power
• Battery-operated equipment needing voltage level monitoring
• Embedded systems utilizing low-voltage logic supplies

Supervisors Procurement Notes

Verify the exact suffix IH26Z-T to confirm the 2.63 V threshold and open-drain output configuration. Confirm RoHS compliance status through official documentation. Check for End-of-Life notices as availability may be limited. Ensure the SOT-23 package matches your PCB footprint requirements. Validate operating temperature range suitability for your specific environment.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with open-drain output is required. Compare against push-pull variants if active drive capability is necessary. Consider the 190 ms delay time for system startup synchronization. Evaluate the 1.2% accuracy against stricter supervision needs. Verify compatibility with the target system's minimum operating voltage of 1.8 V.

Supervisors Part Context

This part belongs to the ISL88001 series of low-power voltage supervisors. It shares architectural similarities with other members like ISL88001IE31Z-T but differs in threshold voltage and output type. The series targets general-purpose power management applications where minimal current draw is critical. It complements Renesas' broader portfolio of power management integrated circuits.
