Texas Instruments Inc. (TI) expands its automotive power management portfolio with TPS658629-Q1 and claims it as the industry's first automotive power management integrated circuit (PMIC) to support the next generation of infotainment and cluster power requirements.

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 14 power voltage rails. The I2C interface enables control of a wide range of sub-system parameters. Its internal registers have a complete set of status information, enabling easy diagnostics and host-controlled handling of fault conditions.

As an automotive PMIC with more than 10 rails, the TPS658629-Q1 offers 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.

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 12mmx12mm PCB space.

The TPS658629-Q1 is now available from TI and authorised distributors. It is offered in an automotive-qualified 169-ball nFBGA package. The TPS658629-Q1 is priced at Rs.313.90 ($7) in quantities of 1,000.
