ISL88001IH46Z-TK

Supervisors Overview

The ISL88001IH46Z-TK is an ultra-low power voltage supervisor from Renesas, designed to monitor supply voltages in portable and battery-operated systems. It features a push-pull output and operates within a wide input voltage range up to 6V. The device is housed in a compact SOT-23-3 package, ensuring minimal board space usage while providing reliable supervision for critical power rails.

Supervisors Feature Summary

• Ultra-low quiescent current consumption for extended battery life
• Push-pull output driver for robust signal integrity
• Compact SOT-23-3 surface-mount packaging

Supervisors Applications

• Portable electronic devices requiring low standby power
• Battery-operated equipment with strict energy constraints
• General-purpose voltage monitoring in embedded systems

Supervisors Procurement Notes

Verify the specific suffix 'TK' indicates tape-and-reel packaging when ordering. Confirm the device status as End-of-Life (EOL) with discontinuation scheduled by the manufacturer. Ensure compatibility with existing design layouts before finalizing procurement plans due to potential supply chain changes.

Supervisors Selection Notes

Select this component for applications prioritizing minimal active current draw over high-speed response times. The SOT-23-3 package limits pin count, so verify that additional functions like manual reset or open-drain options are not required. Compare against the ISL88002/3 series if multiple voltage channels are needed.

Supervisors Part Context

This part belongs to the ISL88001/2/3 family of single-supply voltage supervisors. These devices are engineered for low-power environments where maintaining system stability during brown-out conditions is critical. The family shares similar internal architectures but may vary in threshold voltages or package options.
