  • Product Details

    The MAX25430 combines an automotive-grade buck-boost controller capable of driving up to 5.0A, a USB-PD Analog Front-End (AFE), Legacy USB Charging support and USB Type-C™ protection for USB host or DFP applications. The USB Type-C protection switches provide automotive system-level ESD and 24V short-circuit protection for D+, D-, CC1, CC2, and VCONN. The device also supports legacy USB 2.0 charging modes including BC1.2, Apple° 2.4A, Apple CarPlay°, Apple MFi and USB On-The-Go (OTG).

    The MAX25430B integrates a USB-PD AFE which supports the USB-IF Type-C Port Controller Interface (TCPCI) specification and can interface with any I2C Master in the application.

    The MAX25430A provides CC signal passthrough protection for an external USB-PD controller.

    G-Suffix devices include intelligent detection and protection to avoid high short-circuit currents flowing from the car battery through the cable shield to ground during fault events, preventing car module damage.

    The MAX25430 EVKIT and collateral provides a convenient platform to the design engineer for rapid evaluation with reduced test and firmware development time. The MAX25430 is available in a small 6mm x 6mm 40-pin TQFN package and requires very few external components.
