Texas Instruments Inc. (TI) introduced what it claims as the industry's first automotive power management integrated circuit (PMIC) to support 14 power voltage rails. As an automotive PMIC with more than 10 rails, the TPS658629-Q1 provides all the 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 small package.

The 14-rail 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. Its internal registers have a complete set of status information, enabling easy diagnostics and host-controlled handling of fault conditions.

This PMIC can be designed and factory-programmed depending on the customer's power sequencing specifications without any additional cost. The whole automotive-qualified nFBGA package sports a small footprint as it occupies only small 12mm 12mm PCB space.

The TPS658629-Q1 is now available 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.
