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2.3Ω/2.7Ω(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接口,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 an..
