Functional Diagram
iND10049 is an Automotive USB HUB with advanced functionality including high-speed 480 MB/S ports, Apple CarPlay and Android Auto, capabilities.
The device is a combination of USB Hub with an integrated USB Device supporting three interfaces: I2S audio interface, Mass Storage Class SD Card Host and a HID Class microcontroller access side-channel. iND10049 can support up to three external downstream ports, each of which can withstand an indefinite short of the DP/DM pins to 5V. iND10049 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.
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.
The chip contains a charge measurement function that measures the voltage across an off-chip power control switch to calculate current consumption from VBUS. The charge measurement function also has the ability to issue a microcontroller interrupt if an overcurrent or an over-charge event occurs.
iND10049 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) that allows direct connection to the car battery, from which all the supplies required by the device are generated.
The iND10049 also contains an I2C and a SPI master interface, all of which can be used to communicate with other integrated circuits on a product board.
