ISL6132IR

Supervisors Overview

The ISL6132IR is a dual-channel voltage supervisory circuit manufactured by Renesas Electronics (formerly Intersil). It operates within a supply voltage range of 1.5 V to 5.5 V and features adjustable threshold voltages with a minimum undervoltage threshold of 700 mV. The device monitors two independent input channels and provides active-low reset outputs via open-drain or open-collector configurations. It does not include manual reset functionality or a watchdog timer. The component is housed in a 24-lead QFN package (4x4 mm) with an exposed pad, suitable for surface-mount installation. It supports operation across a temperature range of -40°C to +85°C and consumes a typical operating current of 170 µA.

Supervisors Feature Summary

• Dual-channel supervision with adjustable threshold detection capabilities
• Active-low reset output with open-drain/open-collector configuration
• Compact 24-lead QFN package design with exposed thermal pad

Supervisors Applications

• Multi-rail power system monitoring in embedded electronics
• Voltage supervision for portable devices requiring low quiescent current
• Industrial control systems needing reliable undervoltage/overvoltage detection

Supervisors Procurement Notes

Verify the specific suffix requirements for the ordered part number, as the 'T' variant indicates tape-and-reel packaging while the base model may differ in shipping format. Confirm end-of-life status and obsolescence notices from the manufacturer before finalizing procurement plans. Ensure compatibility with moisture sensitivity level classifications during storage and handling processes.

Supervisors Selection Notes

Select this component when dual-channel voltage supervision is required without manual reset or watchdog features. Verify that the adjustable threshold range accommodates the target supply rails. Consider the 24-QFN package dimensions for PCB layout constraints. Evaluate the 170 µA quiescent current against system power budget requirements.

Supervisors Part Context

The ISL6132 belongs to the Intersil/Renesas supervisory circuit family designed for multi-voltage monitoring applications. It complements other PMIC components by providing dedicated channel supervision without complex interface protocols. The series targets cost-sensitive designs requiring reliable voltage tracking in compact form factors.
