Can DRP support sink and source concurrently? Can DRP support sink and source concurrently? Depending on what is connected to the port, only one role is selected at a single time by a DRP port. What is the cost increase for Dual Port compared t...
Can the TCPP01 be interfaced with a processor from other IC suppliers?Yes. The TCPP01 can be interfaced with other processors. Processors can be USB PD compliant or operate the USB-C at 5V. Refer to the datasheet schematic for IO connections.
If TCPP01-M12 integrates ±8 kV ESD protection on VBUS, why is there an external ESD diode on the VBUS line in the reference schematic?Yes, the TCPP01-M12 integrates ESD protection on VBUS and CC lines. It is compliant with IEC 61000-4-2 Level 4 with ...
What exactly is the VCONN pin?A USB Type-C™ connector has two Configuration Channel pins (CC1 and CC2) used for PDO (Power profile) negotiation.Only one of these two pins is active during the communication; the other one can be used to power a small ...
Why do not TCPP devices integrate ESD protection for high-speed datalines?Not all applications require high-speed data line protection. In order to provide the best cost-effective solution, these protections were not integrated because they are widel...
What is Dead Battery (DB) management in TCPP01-M12 or TCPP03-M20?This is a smart management feature that activates internal pull-down (Rd) resistors when the system battery is fully depleted. When Rd resistors are connected, the Source detects their ...
When do I need 1 or 2 MOSFETS for my load switch on VBUS?Everything is linked to the MOSFET's body diode that can let current flow if there is a voltage or a residual voltage.For example, in a provider path for DRP applications, you always need two M...
What is the best location for the TCPP on a PCB?For efficient ESD protection, place the TCPP as close as possible to the USB-C connector.Also make sure that the ESD capacitor is as close as possible to the TCPP’s CBIAS pin.
Which TCPP device should I use for a sink application with current sense capability?The TCPP03-M20 is a USB Type-C™ Port Protection for Dual Role Power applications. It integrates both gate drivers for provider (source) and consumer (sink) ports so y...
Can I use other protection devices than TCPP for my USB Type-C™ application based on an STM32 MCU?Yes. However, high-voltage control features may be missing in other protection circuits (gate drivers with charge pump for N-MOSFET, discharge paths, sw...
Can I use TCPP protection devices with a microcontroller other than an STM32?Yes, TCPP devices can protect all MCU-based systems on the market. Note that for power delivery, STM32 microcontrollers integrate an UCPD controller, making it easy to cont...
