MAX20046AGTC/V+

MAX20046AGTC/V+ is an automotive Hi-speed USB 2.0 protector. It provides high-ESD and short-circuit protection for the low-voltage internal USB data and USB power line in automotive radio, navigation, connectivity, and USB hub applications. The short-circuit protection features include short-to battery on the protected HVBUS, as well as short-to-HVBUS and short-to-battery on the protected HVD+ and HVD-. Short-to-GND and overcurrent protection are also provided on the protected HVBUS output to protect the internal BUS power rail from overcurrent faults. The device features high-ESD protection to ±15kV air gap and ±8kV contact on the protected HVBUS, HVD+, and HVD- outputs. This device also features an enable input, fault output, 9ms fault-recovery time, 1ms overcurrent-blanking time, and integrated overcurrent auto retry. It is used in automotive USB protection application.
