USB-C protection IC reduces component count in PD controller designs
The STMicroelectronics TCPP03-M20 provides port protection in USB Type-C® Power Delivery (PD) applications, managing protection on provider and consumer paths for a cost-effective implementation of dual-role power systems up to 100W.
The TCPP03-M20 offers a high level of integration, incorporating gate drivers for external N-channel MOSFETs and replacing the discrete protection circuitry typically required to support a dedicated USB PD controller. This means that designs based on the TCPP03-M20 reduce PCB footprint, and enable low-cost microcontrollers to perform full USB Type-C PD negotiation and protection management over I2C.
The controller’s internal architecture provides over-voltage and over-current protection on power supply and configuration lines, with ±8kV of contact discharge protection on the CC pins. The IC quickly isolates the power path within 145ns of an over-voltage, and 8µs of an over-current event, protecting the external MOSFETs and the host MCU, and preventing damage from propagating through the system.
Continuous current sensing is available through an analog output for real-time system monitoring.
The TCPP03-M20 is supplied in a 20-lead QFN package measuring 4.0mm x 4.0mm x 0.75mm.
