The TPS6594-Q1
device provides four flexible multi-phase configurable BUCK
regulators with 3.5 A output current per phase, and one
additional BUCK regulator with 2 A output
current.
All of the BUCK regulators 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. To improve the EMC performance, an integrated spread-spectrum
modulation can be added to the synchronized BUCK switching clock signal. This clock
signal 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, stored in the register map of the
device, can be changed from the default through SPI or I2C interfaces to
configure the device to meet many different system needs. The NVM contains a bit-integrity-error detection feature (CRC) 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 real-time clock (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 voltage monitoring on
the input supply , input over-voltage
protection, voltage monitoring on all BUCK and LDO regulator outputs, register and interface CRC, current-limit, short-circuit protection,
thermal pre-warning, and over-temperature shutdown. The device also includes a Q&A or trigger mode watchdog to monitor for MCU
software lockup, and two error signal monitor (ESM) 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 MCU to take action in response.
