CAT9555中文资料
概述CAT9555是一款基于COMS工艺的器件，它提供了I2C和SMBus在应用中的16位通用并行输入、输出口的扩展。
当应用中需要额外的I/O口来连接传感器、电源开关、LED、按钮、风扇等时，可使用I/O扩展器件实现简单的解决方案。
CAT9555包含两个8位配置寄存器（输入或输出选择）、输入寄存器、输出寄存器、极性反转寄存器和一路兼容I2C/SMBus串行接口。
通过写配置寄存器可将16个I/O口中的任何一个配置成为输入或输出。
系统主控制器可以通过写高电平有效的极性反转寄存器将CAT9555的输入数据反转。
当任何输入口状态改变时，CAT9555就会产生一个低电平中断，该中断可以用来向系统主控器指明输入端口状态的改变。
CAT9555有3个输入管脚来实现扩充I2C地址，最多允许8个器件共用在一个I2C/SMBus总线上。
CAT9555固定的I2C地址与CAT9554相同，只允许8个器件连接接到同一个I2C/SMBus总线上。
特性兼容400KHz I2C总线工作电源电压：2.3V～5.5V低待机电流I/O口可承受5V电压16个I/O口，默认为16个高电平输入口高驱动能力独立的输入输出配置寄存器极性反转寄存器低电平有效中断输出内部上电复位上电时无干扰脉冲信号SCL/SDA输入的噪声滤波器可级联8个器件工业级温度范围提供三种不同的封装形式：与RoHS兼容的24脚SOIC、TSSOP封装和24脚的TQFN封装(4mmx4mm)定制信息结构框图SOIC/TSSOP1234-111213-2021222324应用场合白色电器（洗碗机和洗衣机）手持设备（手机、PDA和数码相机）数据通信（路由器、集线器和服务器）。

_______________________________概述MAX481、MAX483、MAX485、MAX487-MAX491以及MAX1487是用于RS-485与RS-422通信的低功耗收发器，每个器件中都具有一个驱动器和一个接收器。
MAX483、MAX487、MAX488以及MAX489具有限摆率驱动器，可以减小EMI ，并降低由不恰当的终端匹配电缆引起的反射，实现最高250k b p s 的无差错数据传输。
M A X 481、MAX485、MAX490、MAX491、MAX1487的驱动器摆率不受限制，可以实现最高2.5Mbps 的传输速率。
这些收发器在驱动器禁用的空载或满载状态下，吸取的电源电流在120(A 至500(A 之间。
另外，MAX481、MAX483与MAX487具有低电流关断模式，仅消耗0.1µA 。
所有器件都工作在5V 单电源下。
驱动器具有短路电流限制，并可以通过热关断电路将驱动器输出置为高阻状态，防止过度的功率损耗。
接收器输入具有失效保护特性，当输入开路时，可以确保逻辑高电平输出。
MAX487与MAX1487具有四分之一单位负载的接收器输入阻抗，使得总线上最多可以有128个M A X 487/MAX1487收发器。
使用MAX488-MAX491可以实现全双工通信，而MAX481、MAX483、MAX485、MAX487与MAX1487则为半双工应用设计。

MAX5090A/B/C
The MAX5090A/B/C easy-to-use, high-efficiency, highvoltage step-down DC-DC converters operate from an input voltage up to 76V, and consume only 310µA quiescent current at no load. This pulse-width-modulated (PWM) converter operates at a fixed 127kHz switching frequency at heavy loads, and automatically switches to pulse-skipping mode to provide low quiescent current and high efficiency at light loads. The MAX5090 includes internal frequency compensation simplifying circuit implementation. The device can also be synchronized with external system clock frequency in a noise-sensitive application. The MAX5090 uses an internal low on-resistance and a high-voltage DMOS transistor to obtain high efficiency and reduce overall system cost. This device includes undervoltage lockout, cycle-by-cycle current limit, hiccup-mode output short-circuit protection, and overtemperature shutdown. The MAX5090 delivers up to 2A output current. External shutdown is included, featuring 19µA (typ) shutdown current. The MAX5090A/MAX5090B versions have fixed output voltages of 3.3V and 5V, respectively, while the MAX5090C features an adjustable 1.265V to 11V output voltage. The MAX5090 is available in a space-saving 16-pin thin QFN package (5mm x 5mm) and operates over the automotive temperature range (-40°C to +125°C).
