PMIC Improves Infotainment System Power Management

Texas Instruments (TI) is advancing the infotainment and user driving experience in the automobile with new high-performance power management. TI introduced a new power management integrated circuit (PMIC) to enhance infotainment systems.

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 competing 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.

All devices are shipping in volume production. They are available in the following packages and price options in 1,000-unit quantities:

  • TPS659039-Q1: 169-pin, NFBGA package; US$7.60
  • SN74AUP1T34-Q1: 5-pin, SC70 (DCK) package; US$0.28
