Hi team,
Is RSTN input is edge detection? or certain Hold time required to reset the device?
regards,
certain hod time required for proper reset. a 0.1UF external cap is needed to grantee enough RC time.
Hi Brian,
I found following description, but cannot find the RSTN drive recommendation.
How much is the minimum hold time required?
8.2.1 Design Requirement
TUSB211-Q1 requires a valid reset signal as described in the power supply recommendations section. The
capacitor C4 is not required if a microcontroller drives the RSTN pin according to recommendations.
regards,
min hold time is five times of supply ramp time (0 to VCC). so it's depends on your supply ramp time.
Hi Brian,
I am planning to use RSTN to recover from Brownout condition. After Vcc is stable, I will toggle RSTN.
In this case, how long is the hold time required for TUSB211 to detect valid RSTN input?
regards,
Hi Brian,
I would like to know the minimum time required to hold RSTN=Low to reset the device.
regards,
