High-speed USB protectors

31 October 2012 Circuit & System Protection

Maxim recently introduced the MAX16919/MAX16969 Hi-Speed USB 2.0 automotive-grade protectors with iPod/iPhone fast-charge detection and USB host-charger detection for all USB gadgets.

The protectors’ fast-charge detection supports both Hi-Speed USB (480 Mbps) and full-speed USB (12 Mbps) operation, which conveniently lets consumers recharge their USB devices while driving. Additionally, they combine several automotive-specific benefits, including short-to-battery and short-to-ground protections, which are required in today’s harsh automotive environment.

These devices are ideal for automotive radio, navigation, connectivity and USB hub applications.

Maxim also offers system-level modelling and simulation support to achieve the best performance for customer-specific applications. The integrated host-charger detection circuitry and the adjustable current capability (3 A) allow the USB peripheral devices to be charged quickly and efficiently. A low on-resistance BUS switch minimises line drop, ensuring USB compliance.
