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端口输入/输出扩展器，带有LED亮度控制和中断，提供热插入保护

MAX7315是I²C/SMBus™兼容的串行接口外围设备，可为微处理器提供8个I/O端口。每个I/O端口可以单独配置为漏极开路输出，额定输出电流50mA/5.5V；也可以配置为具有瞬态检测的逻辑输入。第9个端口可用作瞬态检测中断或通用输出。输出端口可用于驱动LED或与外部上拉电阻配合提供高达5.5V的逻辑输出。\n\n 器件还集成了8位PWM电流控制，其中4位用于全局控制，对所有的LED输出提供电流粗调，从完全关闭到最亮状态，共有14个亮度级。此外，每个输出还具有各自的4位控制，可进一步将全局设置电流细分为16个等级。另外，电流控制也可配置成单独的8位控制，同时设置所有输出。\n\ • 400kbps、2线串行接口，5.5V容限\n• 2V至3.6V工作\n• 8位PWM LED亮度控制\n• 全局16级亮度控制\n• 独立的16级亮度控制\n\n\n• 自动两相LED闪烁\n• 50mA最大端口输出电流\n• 输出额定5.5V，漏极开路\n• 5.5V输入过压保护\n• 瞬态检测具有中断输出\n• 低待机电流(1.2µA典型值，3.3µA最大值)\n• 小巧的3mm x 3mm、薄型QFN封装\n• -40°C至+125°C工作温度范围\n• 所有端口均可配置为输入或输出;
