PCA9632: 4位Fm+ I2C总线低功耗LED驱动器

PCA9632是一款I²C总线控制型4位LED驱动器,针对红/绿/蓝/黄(RGBA)色彩混合应用进行了优化。PCA9632是PCA9633的直接升级版,功耗降低了40倍。在独立亮度控制模式下,每个LED输出都受控于自有的8位分辨率(256阶)固定频率独立PWM控制器,该控制器工作频率为1.5625 kHz,占空比可在0 %至99.6 %范围内调节,允许将LED设为特定的亮度值。 在集群调光模式下,每个LED输出都受控于自有的6位分辨率(64阶)固定频率独立PWM控制器,该控制器工作频率为6.25 kHz,占空比可在0 %至98.4 %范围内调节,允许将LED设为特定的亮度值。 第五个4位分辨率(16阶)集群PWM控制器具有190 Hz固定频率,可用相同值来调光所有LED。

在闪烁模式下工作时,每个LED输出都受控于自有的8位分辨率(256阶)固定频率独立PWM控制器,该控制器工作频率为1.5625 kHz,占空比可在0 %至99.6 %范围内调节,允许将LED设为特定的亮度值。 闪烁速率由集群频率设定值控制,具有8位分辨率(256阶)。闪烁速率的调节范围为24 Hz至每10.73 s一次。对于6 Hz至24 Hz范围内的集群频率设定值,集群PWM具有6位分辨率(64阶),可调占空比范围为0 %至98.4 %。对于6 Hz至0.09 Hz(每10.73 s一次)范围内的集群频率设定值,集群PWM具有8位分辨率(256阶),可调占空比范围为0 %至99.6 %。

每个LED输出均可关闭、开启(无PWM控制)、设为其各自的PWM控制器值或设为独立和集群PWM控制器值。LED输出驱动器编程设置为5 V时具有25 mA吸电流能力的开漏输出,或5 V时具有25 mA吸电流、10 mA源电流能力的图腾柱。PCA9632工作时的电源电压范围为2.3 V至5.5 V,输出具有5.5 V容差。LED可直接连接LED输出(最高25 mA、5.5 V),而对于电流更大或电压更高的LED,也可采用外部驱动器配合极少量的分立式元件控制。

PCA9632属于最新的超快速模式(Fm+)系列产品。Fm+器件具有更高的频率(高达1 MHz)和更密集的总线操作(高达4000 pF)。

软件可编程LED集群和三个子集调用I²C总线地址允许全部或指定的PCA9632器件集群响应一般I²C总线地址,从而可实现诸如同时开启或关闭所有红灯LED的功能,或者滚动追逐效应(marquee chasing effect),最大程度减少I²C总线命令。

软件复位(SWRST)调用可让主机通过I²C总线复位PCA9632,与上电复位(POR)功能相同;后者可将寄存器初始化为它们的默认状态,将输出设为高阻抗状态。这便提供了方便而快捷的方法,将所有器件寄存器重新配置为相同条件。
