ISL88001IH23Z-T

Supervisors Overview

The ISL88001IH23Z-T is a low-power voltage supervisory circuit manufactured by Renesas Electronics Corporation. It monitors a single input voltage and provides an active-low, push-pull reset output when the monitored voltage falls below or exceeds specific thresholds. The device operates within a supply voltage range of 1.8 V to 5.5 V and features a typical reset delay time of 190 ms. It is housed in a SC-70-3 package and is designed for applications requiring precise power management with minimal current consumption.

Supervisors Feature Summary

• Monitors a single voltage input channel for under-voltage and over-voltage conditions
• Provides an active-low reset signal with push-pull output capability
• Operates with ultra-low quiescent current suitable for battery-powered systems

Supervisors Applications

• Portable electronic devices requiring power supervision
• Battery-operated equipment needing voltage monitoring
• Embedded systems with strict power management requirements

Supervisors Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as per latest manufacturer documentation. Check for end-of-life notices or obsolescence warnings before procurement. Ensure packaging specifications match production requirements. Validate datasheet revisions for accurate electrical characteristics.

Supervisors Selection Notes

Select this component for single-channel voltage monitoring applications. Consider the SC-70-3 package size for space-constrained designs. Verify that the 1.8 V to 5.5 V operating range meets system voltage requirements. Evaluate the 190 ms reset delay against system timing constraints. Assess quiescent current impact on overall power budget.

Supervisors Part Context

The ISL88001 series belongs to Renesas' portfolio of low-power voltage supervisors. These components are part of the broader PMIC category, focusing on simple reset generation without additional features like watchdog timers or manual resets. The ISL88001 variant specifically offers push-pull outputs, distinguishing it from open-drain alternatives in the family.

Supervisors Replacement Considerations

Public confirmed substitute part numbers: PT7M7809ZTEX (Diodes Incorporated), TCM809ZENB713 (Microchip Technology). Verify pin compatibility and threshold voltages before substitution.
