MAX3344EEUE概述

    Title: MAX3344E/MAX3345E USB Transceivers Technical Overview
    1. Product Introduction
    The MAX3344E/MAX3345E are advanced USB transceivers designed to bridge logic-level signals with USB signals and vice versa. These dual-function devices support both full-speed (12 Mbps) and half-speed USB operations as per the USB specification 1.1 and 2.0. Equipped with robust features like ±15kV ESD protection, the transceivers ensure reliable communication between USB devices and host systems.
    Key Features:
    - Bidirectional signal conversion between USB and logic levels.
    - Internal 1.5kΩ pullup resistor supporting full-speed operation.
    - Built-in ±15kV ESD protection on all USB I/O pins (D+, D-, VCC).
    - Ultra-low operating voltage down to 1.65V.
    - Compliant with USB specifications 1.1 and 2.0.

    Applications:
    These transceivers find use across a wide range of devices including cell phones, PDAs, MP3 players, digital cameras, PC peripherals, data cradles, and information appliances.
    2. Technical Specifications
    The following table summarizes the key technical parameters:
    | Parameter | Min | Typ | Max | Unit |

    | VCC Input Voltage | 4.0 | 5.5 | - | V |
    | VL Input Voltage | 1.65 | 3.6 | - | V |
    | Operating Current | 10 | - | 500 | µA |
    | Pullup Resistor Value | 1.410 | 1.500 | 1.540 | kΩ |
    | USBDET Threshold (MAX3344E) | 3.6 | - | 4.0 | V |
    | USBDET Threshold (MAX3345E) | 1.0 | - | 2.8 | V |
    | USB Detector Hysteresis | - | 25 | - | mV |
    Other notable features include:
    - ESD Protection (Human Body Model: ±15kV)
    - Driver Output Impedance: 4.6 to 16.0 Ω
    - Propagation Delay: 10 to 18 ns (Differential Receiver)
    - Differential Receiver Sensitivity: 200 mV
    3. Product Features and Advantages
    The MAX3344E/MAX3345E offers several unique advantages that make it a preferred choice for various applications:
    1. Low Voltage Compatibility: Operates with VL as low as 1.65V, ensuring compatibility with low-voltage ASICs.
    2. Built-in ESD Protection: ±15kV ESD protection on D+ and D- eliminates the need for additional protection circuits.
    3. Enumerate Feature: Allows devices to logically disconnect when unplugged, offering greater flexibility in communication protocols.
    4. Wide Temperature Range: Operates reliably across a temperature range of -40°C to +85°C, suitable for extreme environmental conditions.
    5. Compact Packaging: Available in 4×4 mm UCSP™ and 16-pin TSSOP packages, making it ideal for space-constrained designs.
    4. Application Case Studies and Usage Tips
    The MAX3344E/MAX3345E is versatile enough to suit a variety of use cases:
    - Cell Phone Accessories: It enables seamless communication between mobile phones and host PCs, ensuring compliance with USB specifications.
    - Portable Devices: Supports low-power operation, making it ideal for battery-powered devices.

    Usage Tips:
    1. When designing USB ports, ensure proper termination of D+ and D- with 23.7Ω resistors to meet USB specifications.
    2. For energy-efficient operation, activate suspend mode during periods of inactivity.
    3. When connecting multiple devices, ensure sharing-mode configurations are correctly implemented to avoid data conflicts.
    5. Compatibility and Support
    The MAX3344E/MAX3345E supports seamless integration with existing USB infrastructure and operates effectively with both 3.3V and 5V supply voltages. Maxim Integrated provides comprehensive documentation, design tools, and customer support to assist developers in integrating these transceivers into their product
