Texas Instruments TPS659038-Q1/TPS659039-Q1 Power Management Units

Texas Instruments TPS659038-Q1/TPS659039-Q1 Power Management Unit (PMU) for Processors are integrated circuits designed for automotive applications. The device provides a general-purpose (GP) sigma-delta analog-to-digital converter (ADC) with three external input channels. The device also allows one of the converters to be combined with another 3A regulator to permit up to 9A output current by offering seven configurable step-down converters with up to 6A output current for memory. Each step-down converter can synchronize to an external clock source between 1.7MHz and 2.7MHz, or an internal fallback clock at 2.2MHz.

Eleven LDO regulators are available on the TPS659038-Q1 and six on the TPS659039-Q1. These regulators are for external use and are supplied from either a system or a pre-regulated supply. Power-up and power-down sequences (OTP based) are supported by configuring the power-up and power-down controller. Both devices include a 32kHz RC oscillator to sequence all resources during power up and down. A 16MHz crystal oscillator is also included to quickly generate a stable 32kHz for the system achieving a fast system start-up. Additional features include general-purpose input-output (GPIO) functionality and power mode control for power optimization. The Texas Instruments TPS659038-Q1/TPS659039-Q1 devices are AEC-Q100 qualified for automotive applications.
