技术问答

SGM4546是SGMICRO（圣邦微）公司推出的双通道高速高声压级（SPL）压电驱动器，其内部集成了升压DC/ DC，可实现高驱动电压。SGM4546独特的电路设计提供了非常高速的驱动器，能够将2A的峰值电流提供给高容性负载；并通过匹配的上升和下降延迟时间来提高速度和驱动能力。这些匹配的延迟时间保持了输入到输出脉冲宽度的完整性，以减少定时误差和时钟偏差问题。另外SGM4546采用非重叠驱动技术可以最大限度地降低动态开关损耗。

图1 压电发声器驱动器SGM4546的逻辑符号

压电驱动器SGM4546型号包括SGM4546YTDK14G/TR和SGM4546YPTS16G/TR，封装形式分别为TDFN-3×3-14L和TSSOP-16（裸露焊盘），封装尺寸小，可节省PCB空间尺寸。这款驱动器的供电电压范围为1.8V~5.5V，组合峰值输出电流大小为4A，芯片的引脚定义如图2所示。压电驱动器SGM4546的存储温度范围为-65℃~+150℃，工作温度范围为-40℃~+85℃，工作温度范围广，能够适应恶劣的环境要求。
