MAX25460ATGA/V+

MAX25460 is an automotive 1.5A step-down converter with USB protection/host charger adapter emulator. It combines a 1.5A high-efficiency, automotive-grade, step-down converter, a USB BC1.2 host charger emulator, and high-bandwidth USB protection switches for automotive USB 2.0 host applications. The device also includes a USB load current-sense amplifier and a configurable feedback adjustment circuit that provides automatic USB voltage compensation for voltage drops in captive cables often found in automotive applications. The device limits the USB load current using both a fixed internal peak-current threshold and a user-configurable external current-sense USB load threshold. It allows flexible configuration and advanced diagnostic options for both standalone and supervised applications. Typical applications are automotive radio and navigation, USB port for host and hub applications, automotive connectivity/telematics.
