评估板
为了确保功率器件能够安全且充分发挥性能地工作，栅极驱动器ic的选择十分重要。
rohm的栅极驱动器ic评估板具有以下产品阵容。
考虑到栅极驱动器ic评估板需要连接到设置板上的功率器件以进行评估，所以减小了基板面积。
单通道栅极驱动器ic的评估板除了有1pcs实装品之外，还提供适用于板桥电路的2pcs实装品。
此外 ，通过启用栅极驱动器ic用的spice模型，还可以通过simulation进行应用验证。
使用案例
开发板上栅极驱动器ic的替换案例
栅极驱动器ic评估板可用于替换开发板上的栅极驱动器ic。
不同封装和引脚的栅极驱动器ic很难在开发板上进行直接替换。
栅极驱动器ic评估板的电源、信号输入输出端子的布局考虑到与开发板的布线链接，也可在评估板上使用需要调整的栅极电阻。
