TPA3220: 开漏输出及自动复位

Part Number: TPA3220
您好:
问题1:
TPA3220DDWR,技术资料显示,
PIN3:OTW_CLIP, open drain; active low.是开漏输出,实际测试此引脚悬空,上电后输出5V高电平,保护后输出低电平0V,这不是推挽输出吗?
PIN4: FAULT, open drain; active low.是开漏输出,实际测试此引脚悬空,上电后输出5V高电平,保护后输出低电平0V,这不是推挽输出吗?
                                 
问题2:TPA322ODDWR,技术资料显示,
DEMO的J13短路后,可以实现FAULT保护信号发生的时候,自动复位芯片,是吗?
                                 
请帮忙给于帮助谢谢!
