QT118H-ISG

Overview

The QT118H-ISG is a charge-transfer touch sensor IC from Microchip Technology, designed for detecting near-proximity or direct touch. It operates within a supply voltage range of 2V to 5.5V and features a 14-bit resolution for precise sensing. The device supports up to one input channel and includes an LED driver channel for status indication. It is housed in an 8-SOIC package with dimensions of 0.154 inches (3.90mm) width. The component functions across a temperature range of -40°C to 85°C, ensuring reliability in various environments.

Feature Summary

Capacitive touch and proximity detection capability
Integrated LED driver for visual feedback
High-resolution 14-bit sensing architecture

Applications

Consumer electronics touch interfaces
Industrial control panel inputs
Appliance user interface buttons

Procurement Notes

Verify the specific suffix ISG against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 8-SOIC form factor. Check for any recent lifecycle notifications or obsolescence warnings directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single-channel capacitive touch solution with integrated LED driving is required. Consider the 2V to 5.5V operating range for power supply flexibility. Evaluate the 14-bit resolution against noise immunity requirements in the target application environment.

Part Context

The QT118H series belongs to Microchip's QProx family of charge-transfer sensors. This line offers self-contained digital ICs for touch applications. The ISG suffix typically denotes specific packaging configurations. Related variants include the QT118HA, which provides Flash programmability while maintaining form, fit, and function compatibility.

Replacement Considerations

The QT118HA is documented as a form, fit, and function compatible replacement for the QT118H series. Verify that the Flash programming capabilities of the HA variant do not conflict with system design constraints.
