DPO2039DABQ - USB Type-C Port Protector to Provide Overvoltage and Short Circuit Protection in Automotive Applications
The new automotive-compliant USB Type-C Port Protector, DPO2039DABQ from Diodes Incorporated offers overvoltage and short circuit protection in applications including automotive head units, rear-seat entertainment units, and in-car charging. This AEC-Q100 Qualified and PPAP capable protector provides 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.
The DPO2039DABQ USB Type-C Port protector is the part of company’s Discrete Dataline Protection series and is used in line with the CC1, CC2, and D+ and D- or SBU signals of 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.
The device integrates 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. It features 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.
