UC27211输入PWM电压幅度疑问

Other Parts Discussed in Thread: UCC27211A-Q1, UCC27211

我用UC27211驱动H桥电路产生高压,

我详细查看了UC27211的规格书,对输入PWM幅要求有些不理解。

如果按照如下说明,PWM的幅度应该是3V就行 了吧?

8.3 Feature Description
8.3.1 Input Stages
The input stages of the UCC27211A-Q1 device have impedance of 70-kΩ nominal and input capacitance is
approximately 2 pF. Pulldown resistance to VSS (ground) is 70 kΩ. The logic level compatible input provides a
rising threshold of 2.3 V and a falling threshold of 1.6 V.

但规格书下面的应用好像又说要用12V幅度的PWM?

我想清楚我用MCU产生3.3V的PWM直接连接UC27211的 HI LI 可不可行的。谢谢!!
