Remove load then connect it. LP8866 will trigger error. And the output was turned off.
Can I reset LP8866, and trigger the output turn on without switch power?
感谢您对TI产品的关注!
关于你的咨询,看你的描述,断开负载在连接,你应该是触发了Open LED Faults (OPEN_LED)。
你看下datasheet的7.3.9.3.1 Open LED Faults (OPEN_LED)章节。
But the LED_STATUS bit could be cleared by the interrupt clearing procedure.
7.5.2.2 Clearing Fault Interrupts
你对 LED_STATUS寄存器的STATUS bit and a CLEAR bit写入1,清除下fault。
如果后面负载是正常的,应该是会点亮,
如果新的LED fault被诊断出来,还是会报错。
The detail of open LED faults can be read from bits OPEN_LED and LEDx_FAULT (x = 1...6).
These bits maintain their value until device power-down.
But the LED_STATUS bit could be cleared by the interrupt clearing procedure.
If a new LED fault is detected, LED_STATUS is set and an interrupt generated again.
如果仍有问题,建议你直接问问这个芯片相关的设计工程师看看他们的建议。
