手册中37页中SYS_CTRL2 (0x05) 延时是这样描述的,
DELAY_DIS (Bit 7): Disable OV, UV, OCD, and SCD delays for faster customer production testing.
0 = Normal delay settings
1 = OV, UV, OCD and SCD delay circuit is bypassed, creating zero delay (approximately
250 ms).
我是这样理解当DELAY_DIS =0 时延时是正常按参数设置
DELAY_DIS =1时延时为0 (大约250ms)
但我设置 DELAY_DIS = 0.保护就失效
DELAY_DIS = 1时保护时间太短了,过流和短路时间基本一样,请问还有关联的寄存需要设置吗.还是我理解不对
