8-Port I/O Expander with LED Intensity Control and Interrupt

General Description The MAX7315 I2C-/SMBus-compatible serial interfaced peripheral provides microprocessors with 8 I/O ports. Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA at 5.5V, or a logic input with transition detection. A ninth port

8端口輸入/輸出擴展器，帶有LED亮度控制和中斷，提供熱插入保護

MAX7315是I2C/SMBus?兼容的串行接口外圍設(shè)備，可為微處理器提供8個I/O端口。每個I/O端口可以單獨配置為漏極開路輸出，額定輸出電流50mA/5.5V；也可以配置為具有瞬態(tài)檢測的邏輯輸入。第9個端口可用作瞬態(tài)檢測中斷或通用輸出。輸出端口可用于驅(qū)動LED或與外部上拉電阻配合提供高達5.5V的邏輯輸出。\n\n 器件還集成了8位PWM電流控制，其中4位用于全局控制，對所有的LED輸出提供電流粗調(diào)，從完全關(guān)閉到最亮狀態(tài)，共有14個亮度級。此外，每個輸出還具有各自的4位控制，可進一步將全局設(shè)置電流細分為16個等級。另外，電流控制也可配置成單獨的8位控制，同時設(shè)置所有輸出。\n\ ? 400kbps、2線串行接口，5.5V容限\n? 2V至3.6V工作\n? 8位PWM LED亮度控制\n? 全局16級亮度控制\n? 獨立的16級亮度控制\n\n\n? 自動兩相LED閃爍\n? 50mA最大端口輸出電流\n? 輸出額定5.5V，漏極開路\n? 5.5V輸入過壓保護\n? 瞬態(tài)檢測具有中斷輸出\n? 低待機電流(1.2μA典型值，3.3μA最大值)\n? 小巧的3mm x 3mm、薄型QFN封裝\n? -40°C至+125°C工作溫度范圍\n? 所有端口均可配置為輸入或輸出;
