PN7150 next interrupt too short

[peterwu]

PN7150 rise a new interrupt after I2c read .

But sometime it too short (ex : 72us ), that my host can not detect new interrupt. (even I reduce debound time )

Is there any cfg I can set pn7150 to rise next interrupt to 100ms or more ?

[peterwu]

we config host interrupt to 

1. EDGE trig 

2. polarity high 

usually , it work fine to receive pn7150 irq .

but there is few chance can not receive irq. 

After we checked the scope, the 2nd irq come too fast (  72us ) .

so we still think how to fix it.

Maybe you use a slower MCU or put too many codes in the interrupt routine.

Hi Peter,

There is method to configure the active state of IRQ signal, but no way to modify the width, why not using the edge sensitive interrupt?

BTW, which active state did you set for IRQ signal in that case? High or Low?

Have a great day,
Kan
