ISL88708IB844Z-TK

Supervisors Overview

The ISL88708IB844Z-TK is a single-channel power supply management circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2 V to 5.5 V, with a rated voltage of 5 V and a threshold of 4.38 V. The device provides reset signals with a minimum timeout of 140 ms and supports both high-active and low-active logic levels. It features open-drain and push-pull outputs, housed in an 8-SOIC package with a width of 3.90 mm. The component functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for monitored power supplies
• Offers configurable active-high or active-low reset output states
• Supports dual output drive configurations including open-drain and push-pull modes

Supervisors Applications

• Industrial control systems requiring power supervision
• Embedded systems needing reliable power-on reset generation
• Microcontroller unit (MCU) power supply monitoring circuits

Supervisors Procurement Notes

Verify the specific suffix 'TK' against official Renesas documentation, as standard listings typically reference 'IB844Z'. Confirm current availability status, as related variants are marked as obsolete. Ensure the ordering part number matches the exact package and tape-and-reel specifications required for the design.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a 4.38 V threshold is required. Consider the 140 ms minimum reset delay and the available output drive types. Verify compatibility with the system's operating voltage range of 2 V to 5.5 V and the industrial temperature requirements.

Supervisors Part Context

The ISL88708 belongs to a family of power supply management ICs designed for supervising single voltage rails. It complements other Renesas components like the ISL88716 and ISL88813, which share similar documentation structures. This series addresses basic reset generation needs in compact surface-mount packages.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Check for direct pin-compatible alternatives from Renesas or verify if the obsolete status necessitates a redesign with newer supervisor ICs.
