The RT5147 provides a highly-integrated multi-channel system power management solutions designed to fulfill the performance, efficiency, and feature requirements of SSD applications. It features four buck regulators and two LDOs, delivering multiple output voltages to accommodate various applications with different Voltage Identification (VID) requirements. The power-on sequence is configurable, offering enhanced flexibility for system design.Additionally, the RT5147 is equipped with 8 configurable GPIO pins to meet diverse system hardware control requirements. These GPIOs can be programmed for a variety of functions, including PWRDIS/ Sleep/ Deep Sleep settings for PMIC state machine control, Enable/Disable settings for Buck1 and Buck2, VID control settings for Buck3 and Buck4, nRESET pin functionality to monitor PMIC power good status, and configuration as External Enable (External_EN) and External Power Good (External_PG) signals. Furthermore, the GPIOs support three-state configuration through I<sup>2</sup>C interface when operating in the normal mode.The RT5147 is designed to operate within a recommended junction temperature range of -40°C to 125°C, and an ambient temperature range of -40°C to 85°C.
