ISL8701AIBZ

Supervisors Overview

The ISL8701AIBZ is an adjustable quad voltage sequencer manufactured by Renesas Electronics under the Intersil brand. It monitors a single input and provides four independent outputs to sequence power rails. The device operates within a supply voltage range of 3.3 V to 24 V and features active low, open-drain outputs with manual reset capability. It lacks a watchdog timer and battery backup switching. The component is housed in a 14-lead SOIC package and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides four independently adjustable output channels for sequential power management
• Features active low open-drain outputs compatible with various logic families
• Includes manual reset functionality for controlled system initialization

Supervisors Applications

• Multi-rail power sequencing in industrial control systems
• Voltage ordering in telecommunications infrastructure equipment
• Power management in embedded computing platforms requiring strict startup sequences

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing lots. Validate package integrity and pin configuration against original datasheet specifications before integration into new designs.

Supervisors Selection Notes

Select this component when precise timing between multiple voltage rails is required without complex external circuitry. Ensure the single monitored input architecture aligns with system monitoring needs. Verify that the open-drain output type suits the downstream load requirements and pull-up resistor configurations available in the design.
