Hi
I have some question for BQ24392 DCD detect timing.
I read about this device data sheet.
About Flow Chart of Detection Sequence in Data sheest , DCD ( Data Contact Detection) judgment
need 600msec by this flow chart.
[ Question ]
1) The 600msec need detect for DCD (Data Contact Detection) in this Flow Chart.
Question is deglitch time for this detect function
We think actualy detect time need 600msec + ?? msec . * ??msec is deglitch time.
And we want to know about this deglitch time spec.
Beacuse of Control Host side MCU software need waiting this total (600msec + Deglitch time ) time
for detect timing.
Could you tell us about tis DCD Detect deglitch time??
2) D+ / D- detect and SDP judgment time spec.
We want to know about t D+/ D- detect judgment time spec for SDP.
Data sheet Flow has SDP detect time flow about
PRIMARY Detection -> Standard Downstrem Port -> USB Switch ON / OFF
Question is detection and deglitch time spec for USB Switch ON / OFF.
Could you tell us about this detection and deglitch time until USB SW ON / OFF?
3) About IDLE condition ( VBUS > VBUS_VALID) detect time and deglitch time.
USB connector some time not stable , For instance likea " chattering. "
We think IDLE detect spec has deglitch time for like a chattering eliminator.
Could you tell us about this IDLE detect deglitch time ??
Why we have this question??
Now we making MCU software for this device statsu control.and need about these spec for MCU
waiting time decide.
Thanks and Regard
Jasper
