TI introduces first 14-rail PMIC for infotainment and cluster applications

October 17, 2011 // By Christoph Hammerschmidt
Texas Instruments has introduced  an automotive power management integrated circuit (PMIC) to support 14 power voltage rails. As the industry's first automotive PMIC with more than 10 rails, the TPS658629-Q1 provides all power supply functions and reduces board space for infotainment, navigation and LCD/TFT cluster applications by integrating multiple regulated power supplies, system power management and display functions in one package.

The TPS658629-Q1 has 3 DC-DC Buck Converters, 11 LDOs, four programmable PWM outputs, two RGB LED drivers and one WLED driver to support the next generation of infotainment and cluster power requirements. The I2C interface enables control of a wide range of subsystem parameters. Internal registers have a complete set of status information, enabling easy diagnostics and host-controlled handling of fault conditions.

The device can be factory-programmed to the customer's own power sequencing specifications without any additional cost.  With a 12-mm x 12-mm automotive-qualified nFBGA package, it features a remarkably small footprint.

The TPS658629-Q1 is available for ordering now from TI and authorized distributors. It is offered in an automotive-qualified 169-ball nFBGA package. The TPS658629-Q1 is priced at $7.00 in quantities of 1,000. Samples and evaluation modules are available.
