Texas Instruments (TI) has launched a new power management integrated circuit (PMIC), as well as the industry's first USB 3.0 devices, and a free-positioning Qi wireless power transmitter for automobiles. The new PMIC is claimed to enhance infotainment systems, while the other devices will provide a more enjoyable, convenient and connected experience.
 
The TPS659039-Q1 PMIC will power next-generation infotainment system designs through the DRA74x ‘Jacinto 6’ processor, and will simultaneously minimise system-level power consumption, TI said. It added that the PMIC also improves thermal management through adaptive voltage scaling, thereby reducing electromagnetic interference (EMI) through internal and external synchronisation. This is said to enable flexibility in design with power sequencing by saving board space, reducing development time and the need for an additional microcontroller.
 
The TPS659039-Q1 PMIC gives users extremely fast access to driver information, camera views, navigation system and head-up display, as it powers on in 15 milliseconds. This PMIC also has the flexibility to power both dual-core and quad-core ARM Cortex-15 processors, for automotive and industrial applications.
 
The company’s new USB Hub controllers and  USB-to-SATA bridge allow USB 3.0 connectivity as an industry-first in automobiles for up to four USB ports, TI noted. These devices enable USB 3.0 communications with 5-Gbps data flow for multimedia applications including mobile phones, external hard disk drives and solid disk drives for applications like portable gaming or navigation systems. The two Hub controllers' downstream ports support USB battery charging 1.2, charging downstream port, handshaking and a dedicated charging port mode when the upstream port is not connected, TI explained. The USB 3.0 Hub controllers are claimed to offer USB charging and higher receive sensitivity than competing devices, resulting in reduced board space and easier system design.
 
Finally, the company’s 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 integrated circuit, 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, TI said.
