Texas Instruments, Inc. aims to advance the infotainment and user driving experience in the automobile with seven new high-performance power management, SuperSpeed USB and logic products. TI today introduced a new power management integrated circuit (PMIC) 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, more convenient connected experience.
TI’s TPS659039-Q1 PMIC powers the DRA74x “Jacinto 6” processor and minimizes system-level power consumption in next-generation infotainment system designs. Compared to earlier devices, the PMIC improves thermal management through adaptive voltage scaling, reduces electromagnetic interference (EMI) through internal and external synchronization, and enables design flexibility with power sequencing – saving board space, reducing development time and the need for an additional microcontroller.
The TPS659039-Q1 powers on in only 15 milliseconds, which gives users lightning-fast access to driver information, camera views, the navigation system and head-up display. Designers can also choose this PMIC to power dual- and quad-core ARM® Cortex-15 processors in automotive and industrial applications.
In complex infotainment systems, the new SN74AUP1T34-Q1 and TXS0102-Q1 voltage level translators solve voltage mismatch issues by simply connecting incompatible CMOS logic communication between the processor and legacy peripheral devices operating at a different voltage.
TI’s new TUSB8041-Q1 and TUSB8020B-Q1 USB Hub controllers and TUS9261-Q1 USB-to-SATA bridge allow USB 3.0 connectivity for the first time 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 driver or passengers.
All devices are shipping in volume production. They are available in the following packages and price options in 1,000-unit quantities: TPS659039-Q1 in a 169-pin NFBGA package, US$7.60; SN74AUP1T34-Q1 in a 5-pin SC70 (DCK) package, US$0.28; TXS0102-Q1 in an 8-pin VSSOP package, US$0.38; TUSB8020-Q1 in a 48-pin QFP package, US$3.75; TUSB8041-Q1 in a 64-pin QFP package, US$5.56; TUSB9261-Q1 in a 64-pin QFP package, US$5.56; and the bq50041 4Q in a 48-pin 7-mm by 7-mm VQFN, US$3.92.
