Texas Instruments (TI) has released seven new high-performance power management, SuperSpeed USB and logic products in an effort to enhance the infotainment and user driving experience in vehicles.
The latest product is a new power management integrated circuit (PMIC) designed to enhance infotainment systems. TI also introduced the industry’s first USB 3.0 devices and a free-positioning Qi wireless power transmitter for automobiles that enable a more enjoyable and convenient connected experience.
Powering next-generation infotainment systems
TI’s TPS659039-Q1 PMIC powers the DRA74x ‘Jacinto 6’ processor and minimises system-level power consumption in next-generation infotainment system designs. The PMIC delivers benefits such as improving thermal management through adaptive voltage scaling, reducing electromagnetic interference (EMI) through internal and external synchronisation, and enabling design flexibility with power sequencing, to save board space, reduce development time and eliminate the need for an additional microcontroller.
Powering on in only 15 milliseconds, which gives users lightning-fast access to driver information, camera views, navigation system and head-up display, the TPS659039-Q1 PMIC can also be used to power dual- and quad-core ARM Cortex-15 processors in automotive and industrial applications.
Convenient USB connectivity and wireless charging
TI’s new TUSB8041-Q1 and TUSB8020B-Q1 USB Hub controllers and TUS9261-Q1 USB-to-SATA bridge allow USB 3.0 connectivity in the automobile for up to four USB ports. The TUSB devices enable USB 3.0 communications capability with the 5-Gbps data flow required for multimedia applications, including mobile phones, or external hard disk drives (HDD) and solid disk drives (SDD) for applications such as portable gaming or navigation systems. The two Hub controllers’ downstream ports support USB battery charging 1.2, charging downstream port (CDP), handshaking and a dedicated charging port (DCP) mode when the upstream port is not connected. The USB 3.0 Hub controllers enable USB charging and higher receive sensitivity than competing devices, reducing board space and easing system design.
The new bq500414Q is the industry’s first automotive-qualified, Qi 1.1-compliant wireless power transmitter to offer free-positioning, foreign object detection and system-level EMI enhancement. The transmitter IC, which enables wireless charging from an automotive console with an A6 coil design, provides a simpler, stress-free charging experience for the vehicle’s occupants.
