Functional Diagram
iND10051 is an Automotive USB HUB with advanced functionality including high-speed 480 MB/S ports, Apple CarPlay and Android Auto, and USB Type C power delivery capabilities.
The device is a USB Hub with an integrated USB Device supporting I2S audio interface and a HID Class microcontroller access side-channel. iND10051 can support up to two external downstream ports, each of which can withstand an indefinite short of the DP/DM pins to 5V.
iND10051 also implements a USB Host to Host Bridge component that enables dual role functionality at a downstream USB Hub port, allowing them to connect to a vehicles infotainment system via Apple CarPlay without requiring a special cable.
iND10051 features two integrated USB-PD 3.1 controllers and port control and configuration channel (CC) for support of USB Type-C connectors.
The device contains a flexible charging emulator termination (FCET) that allow each port to independently function as a USB battery charger. The FCET supports USB BC1.2 DCP/CDP specification as well as support for Apple and Samsung proprietary Charging Modes. In addition, the dual integrated USB PD 3.1 controllers reduce the cost of implementing a data plus power solution.
iND10051 features an integrated Arm® Cortex M0 microcontroller that mediates data transfers to and from the USB Device. The Arm Cortex M0 microcontroller can also mediate the handshaking required for successful flexible charging emulator termination implementation It also includes an integrated power management block (PMU) directed connected to the car battery, from which all the supplies require by the device are generated.
The iND10051 also contains an I2C, SPI master interface, UART, and LIN interface, all of which can be used to communicate with other integrated circuits on a product board.
