ISL88013IH546Z-TK

Supervisors Overview

The ISL88013IH546Z-TK is a single-channel voltage supervisor IC manufactured by Intersil, housed in a 5-lead SOT-23 package. It features an adjustable power-on reset (POR) function and monitors a single input voltage. The device operates within a supply voltage range of 1.7V to 5.5V and includes a push-pull or open-drain output configuration. Key electrical parameters include a threshold voltage of 4.64V, a typical quiescent current of 11.5µA, and an operating temperature range from -40°C to +85°C. The component is marked with the code AHM.

Supervisors Feature Summary

• Provides adjustable power-on reset functionality for reliable system initialization
• Monitors a single voltage input channel with high accuracy
• Offers low quiescent current consumption for energy-efficient operation
• Available in a compact 5-lead SOT-23 surface-mount package

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing reliable power-on reset
• Embedded controllers monitoring main supply rails
• Industrial equipment operating in extended temperature ranges

Supervisors Procurement Notes

Verify the manufacturer status as Intersil is now part of Renesas Electronics. Confirm the specific suffix Z-TK indicates tape-and-reel packaging if required for automated assembly. Check for obsolescence notices, as this part may be discontinued. Ensure the replacement ISL88011IH546Z-TK meets all functional requirements before substitution. Validate the AHM marking code against official datasheets to confirm authenticity.

Supervisors Selection Notes

Select this component when a single-channel supervisor with adjustable POR is needed. Consider the 4.64V threshold specifically for applications requiring precise reset timing at that voltage level. Evaluate the 11.5µA quiescent current against system power budgets. Ensure the SOT-23-5 package fits the PCB layout constraints. Verify compatibility with the target operating temperature range of -40°C to +85°C.

Supervisors Part Context

This device belongs to the ISL8801x family of voltage supervisors, which includes variants like the ISL88011 through ISL88015. These parts share similar architectures but differ in threshold voltages and output configurations. The ISL88013 series is designed for general-purpose monitoring tasks where a single reset signal is sufficient. The family emphasizes low power consumption and small form factors suitable for modern portable electronics.

Supervisors Replacement Considerations

The official recommended replacement is the ISL88011IH546Z-TK. Verify that the replacement maintains the same 4.64V threshold and package type. Confirm pinout compatibility to ensure direct board-level substitution without redesign.
