技术问答

电动升降儿童桌可一键升降就能轻易地调整到合适的高度，本文介绍中科微的微特步进电机驱动器 HR4988应用在电动升降儿童桌的特点。

HR4988的输出驱动能力达到38V和±2A，24V2A的电机能使双极性步进电机以全、半、1/4,1/8,1/16步进模式工作。使用1/16步进模式可使升降速度固定在15mm/s。

在步进操作期间，芯片内部电路可以自动的控制其PWM操作工作在快、慢及混合衰减模式。在混合衰减模式下，器件初始经过一段时间的快衰减后，将切换至慢衰减模式直至固定关闭时间结束。混合衰减模式控制不但降低了电机工作时产生的噪声，还增加了步进的准确性，同时减小了整机功耗。HR4988具有带迟滞额过热保护、欠压锁定及过流保护，保护电机免受损坏。
