Product Overview: TPS65058RGERG4 from Texas Instruments

The TPS65058RGERG4 is a versatile, multi-channel power management integrated circuit (PMIC) designed by Texas Instruments (TI) to meet the demanding needs of complex, portable, and battery-powered systems. This highly integrated solution provides a compact and efficient way to manage power requirements for a variety of applications, including smartphones, tablets, and other handheld devices.

Key Features

• Multiple Voltage Rails: It offers two step-down converters with integrated FETs and four low-dropout (LDO) regulators, allowing for a variety of voltage outputs to power different components within a system.
• High Efficiency: The step-down converters are capable of operating at up to 2.25MHz, enabling the use of small inductors and capacitors, which helps to maximize efficiency and minimize the solution size.
• Adjustable Outputs: The output voltages of the LDOs and converters can be adjusted via an external resistor divider, providing flexibility in matching the power supply to the specific needs of the application.
• Power Sequencing: The device includes programmable power-on sequencing, an essential feature for systems requiring a specific start-up sequence for different power rails.

Advanced Protection Features

• Over-Temperature Protection: The TPS65058RGERG4 includes thermal shutdown functionality that protects the device and the system in the event of excessive temperatures.
• Under-Voltage Lockout (UVLO): Ensures the device operates at adequate power levels, shutting down the system if input voltage falls below a certain threshold to prevent damage.
• Over-Current Protection: Each channel has built-in current limit protection to safeguard the PMIC and downstream components from excessive current draw.

Package and Availability

The TPS65058RGERG4 is available in a compact 24-pin VQFN package, ensuring a small footprint on the PCB. It is designed for the industrial temperature range, making it suitable for a wide range of environmental conditions. As a product of Texas Instruments, customers can expect high reliability and performance from this PMIC.
