Low-voltage power management unit claims fastest start-up time for instant-on automotive applications

February 11, 2013 // By Paul Buckley
Texas Instruments Incorporated has introduced a low-voltage power management unit with the fastest start-up time of less than10 ms for demanding instant-on automotive applications, such as graphical cluster, infotainment and advanced driver assistance systems (ADAS).

The TPS659119-Q1 is optimized to work with TI's automotive OMAP processors, including the DRA6x family (codenamed 'Jacinto') of infotainment processors, and other ARM Cortex-A offerings. In addition, the TPS659119-Q1 is factory-programmed and has customizable power-up and power-down sequencing based on the customer's processor of choice and system power needs.      

The TPS659119-Q1 has three efficient step-down DC/DC converters; two with dynamic voltage scaling and one for input/output (I/O) power.     

The device has a control signal that enables one external buck controller for external FETs to support a high current rail when necessary.     

With eight low dropout (LDO) voltage regulators and one real-time clock (RTC) LDO, the TPS659119-Q1 provides flexible output power to serve multiple processors.     The TPS659119-Q1 is optimized for TI's automotive OMAP processors, including the DRA6x family of infotainment processors.        

The TPS659119-Q1 evaluation module (EVM) is available to speed the evaluation of the TPS659119-Q1.  Priced at $99.00, the evaluation module is available upon request at www.ti.com/tps659119evm-pr      

Availability and Pricing     

The TPS659119-Q1 comes in a HTQFP 80-pin package and is available now for ordering   at a suggested retail price of $5.61 in 100-unit quantities.
