DPO2039DABQ - USB Type-C Port Protector to Provide Overvoltage and Short Circuit Protection in Automotive Applications
The new automotive-compliantUSB Type-C Port Protector,DPO2039DABQfromDiodes Incorporated offersovervoltage and short circuit protectionin applications including automotive head units, rear-seat entertainment units, and in-car charging. ThisAEC-Q100 Qualified and PPAP capable protectorprovides future-proof ports for smart devices and other peripherals and is one simple yet effective solution that provides in-line protection for the data lines of USB Type-C ports.
TheDPO2039DABQUSB Type-C Portprotector is the part of company’s Discrete Dataline Protection seriesand is used in line with theCC1, CC2, and D+ and D- or SBU signalsof a USB Type-C port to protect the device from electrostatic discharge (ESD), faults caused by the presence of an excessive voltage or short circuit to VBUS on any of the four data lines, or an over-temperature event.
Thedeviceintegrates high-performance MOSFETs, gate drivers, and control logic to isolate the data lines if a fault condition is detected. The typical overvoltage fault detection response time is 100ns. Thermal shutdown is preconfigured with a threshold of +150°C and +20°C hysteresis. The DPO2039DABQ is available now, priced at $0.35 in 3000 piece quantities. Itfeatures low insertion loss, with an on-resistance of typically 300mΩ and equivalent capacitance of 50pF or less. It has no negative impact on the bandwidth of the data lines. The high level of ESD protection eliminates the need for external transient voltage suppressors.
