Maxim MAX14829低功耗IO -Link收发器解决方案Maxim公司的MAX14829是具有两个驱动器的低功耗IO-Link设备收发器，集成了工业传感器所需要的高压功 能.器件具有两个反向极性保护的超低功耗驱动器，工作电压为9V到60V. MAX14829的高压容差允许使用 micro-TVS,从而简化了瞬态保护.小型(4mm x 4mm) 24引脚TQFN封装降低了占位尺寸，小型传感器驱动器 开态电阻为2.3Q/2.7Q(典型).工作功耗典型值为60mW,可选择驱动器电流100A到330A.引脚控制接口用来 配置和监视.UART 接D,3.3V和5V低噪音线性稳压器.工作温度-40°C到+125°C，主要用在工业传感 器，IO-Link®传感器和激励器以及安全应用.本文介绍了 MAX14829主要优势和特性，功能框图,应用电路图以 及评估板MAX14829 EVK主要特性,电路图，材料清单和PCB设计图.The MAX14829 integrates the high-voltage functions commonly found in industrial sensors. The MAX14829 features two ultra low-power drivers with active reverse-polarity protection and is specified for operation with supply voltages from 9V to 60V. The high-voltage tolerance of the MAX14829 allows for the use of micro-TVS, simplifying transient protection.Pins are used to configure and monitor the device. Driver overload and supply monitor outputs are available. Pin-control allows for operation with switching sensors that do not use a microcontroller.Two integrated linear regulators (3.3V and 5V) provide low-noise analog and logic supply rails for the device or external circuits.The MAX14829 is available in a (4mm x 4mm) 24-pin TQFN package and is specified over the extended -40°C to +125°C temperature range.MAX14829主要优势和特性：Low Power Dissipation Reduces the Thermal Footprint for Small Sensors 2.3Q/2.7Q (typ) Driver On-Resistance60mW (typ) Operating Power DissipationHigh Configurability and Integration Reduce SKUs Auxilary 24V Digital Output (DO) and Input (DI)Selectable Driver Current: 100mA to 330mAUART Interface3.3V and 5V Low-Noise Linear RegulatorsOptional External Transistor Supports Higher Regulator Load CapabilitySupervisors Monitor 24V SupplySelectable Driver Integrated Protection Enables Robust Communication 65V Absolute Maximum Ratings on Interface and Supply Pins Allows for Flexible TVS Protection9V to 60V Specified OperationGlitch Filters for Improved Burst and Noise ResilienceThermal Shutdown Autoretry CyclingHot-Plug V24 Supply ProtectionReverse Polarity Protection of All Sensor Interface Inputs/Outputs-40°C to +125°C Operating Temperature RangeMAX14829 应用：Industrial SensorsIO-Link® Sensors and ActuatorsSafety Applications图1.
