Evaluation Kit for the MAX20463


Please check latest availability status for a specific part variant.

Description

The MAX20463 evaluation kit (EV kit) demonstrates the MAX20463; a small, integrated USB Type-C™ solution for automotive radio, navigation, connectivity, and USB head units and infotainment applications. The device provides a one-chip solution to convert an existing downstreamfacing port from supporting the USB-A connector to supporting the USB Type-C connector.

The device features an integrated USB Type-C interface to control the new configuration channel (CC) pins found in the USB Type-C connector. It supports the downstreamfacing port (DFP) role and supports VBUS current limits including 1.5A and 3.0A. The MAX20463 can coexist with BC1.2 and Apple charging technologies, as these are controlled by the host emulator in the upstream module.

An integrated high-side power switch protects the device against faults and allows most fault conditions to be detected and handled by the upstream 5V power supply. This avoids possible contention, in which both the upstream 5V power supply and the MAX20463 detect the same fault and simultaneously try to resolve it.

The BIAS circuitry provides a solution to the transient conditions seen in automotive USB charging applications. The device is designed to stay powered on during the CC attach process even if VBUS droops due to an overcurrent, or other low voltage condition, for a short period of time. The period of time that the part can stay powered on can be configured by the module design engineer to provide the time required for the upstream 5V power supply to detect and handle the fault. The device stay-on time is determined by the amount of capacitance on BIAS, which must be at least 22µF, but can be increased above this value. The device and its solution circuit are designed to conform to the USBIF specification for short-to-ground response.
