The TPS6594-Q1 device provides four flexible multi-phase configurable step-down converters with 3.5 A per phase, and one additional step-down converter with 2 A capability.
All of the bucks can be synchronized to an internal 2.2 MHz or 4.4 MHz or an external 1 MHz, 2 MHz, or 4 MHz clock signal. An integrated spread-spectrum modulation can be added to the synchronized buck switching clock signal to improve the device’s EMC performance, which can also be made available to external devices through a GPIO output pin. The device provides four LDOs: three with 500 mA capability, which can be configured as load switches; one with 300 mA capability and low-noise performance.
Non-volatile memory (NVM) is used to control the default power sequences and default configurations, such as output voltage and GPIO configurations. The NVM is pre-programmed to allow start-up without external programming. Most static configurations can be changed from the default through SPI or I2C registers to configure the device to meet many different system needs. As a safety feature, the NVM contains a bit-integrity-error detection feature to stop the power-up sequence if an error is detected, preventing the system from starting in an unknown state.
The TPS6594-Q1 includes a 32 kHz crystal oscillator, which generates an accurate 32 kHz clock for the integrated RTC module. A backup-battery management provides power to the crystal oscillator and the RTC module from a coin cell battery or a super-cap in the event of power loss from the main supply.
The TPS6594-Q1 device includes protection and diagnostic mechanisms such as register and interface CRC, short-circuit protection, thermal monitoring, and shutdown. The device also includes a Q&A or trigger mode watchdog to monitor for software lockup, and 2 system error monitoring inputs with fault injection options to monitor the error signals from the attached SoC or MCU. The TPS6594-Q1 can notify the processor of these events through the interrupt handler, allowing the processor to take action in response.
