Part Number: TPD4S214 In some older USB switch designs we have recommended having a discharge resistor in parallel with Vbus to slowly discharge the output cap/prevent a reverse voltage/current situation. Is this recommended for TPD4S214 and what value…
Part Number: TPD4S214 Many USB reference designs include a ferrite bead on Vbus, located very near the USB connector, to suppress noise. The reference designs for the TPD4S214 do not include a ferrite bead.
Does the TPD4S214 device filter noise on Vbus…
Part Number: TPD4S214 Hi,
we are looking for a USB current limit device that could tolerate 10V at VBUS, since they have met VBUS transient that break the USB current limit device. And during the surge test, the TVS on VBUS could clamp VBUS below 10V…
Part Number: TPD4S214 Hi Support team
My customer is using the TPD4S214 in a product and are seeing surged when a device is connected . they are asking about response time, so for example, if the limit is set to 500mA and the current surges to 550mA,…
Part Number: TPD4S214 Hi Team, My customer is looking for OVP & OCP device for USB OTG. The requirement is the following. - over voltage protection up to 28V VBUS - OVLO (output overvoltage lockout) threshold is 6~7V - current limit is adjustable more than…
Part Number: TPD4S214 Hi.
We are having trouble designing the TPD4S214 and have an inquiry.
The FLT pin and the ADJ pin are floating in the circuit, and the EN pin is controlled by the controller.
The problem is that the signal of the DET Pin is set to…
Part Number: TPD4S214 Hi,
Am I allowed to keep 5V on the V_OTG_IN pin even when there is an external 5V being supplied to VBUS? Basically I'm trying to determine whether or not I need to disable my internal 5V that I supply to V_OTG_IN when an external…
Part Number: TPS2547 Other Parts Discussed in Thread: TPD4S014 , TPD4S214 Hi Team,
Customer is wondering if they need to add a OVP(in case end user add a >5V source) at our TPS2547 output side, how to protect it ?
Clamping Diode or OVP part ?
Another…
