The HT82M25B-18DIP is a USB mouse encoder IC manufactured by Holtek. It is designed to interface with the sensors of a traditional mechanical mouse and translate the movements into USB signals that can be recognized by a computer. This chip is a key component in creating wired USB mice.

Applications:

• Wired USB mice

Features:

• USB mouse encoder
• Interfaces with mechanical mouse sensors
• Supports standard USB mouse protocols
• 18-DIP package

Benefits:

• Standard Interface: Provides a standard USB interface for easy connection to computers.
• Simple Implementation: Simplifies the design of wired USB mice.
• Cost-Effective: Provides a low-cost solution for mouse encoding.

Additional Details:

The HT82M25B-18DIP takes the quadrature signals from the mouse's X and Y axis sensors and converts them into USB mouse data packets. These packets are then transmitted to the computer via the USB interface. The IC supports the standard USB mouse protocols, allowing it to be easily recognized and used by operating systems. The HT82M25B-18DIP is packaged in an 18-pin Dual In-line Package (DIP). For detailed specifications, pinout diagrams, and application notes, refer to the official Holtek datasheet.
