The Texas Instruments TPS2115ADRBT is a power management integrated circuit (PMIC) designed to provide low voltage dropout performance and flexibility in OR-ing applications. The device features a wide input voltage range, integrated ESD protection, and an integrated ideal diode between +3.3V, +5V, and +12V supplies. The PMIC is ideal for use in enterprise servers and storage systems where space and efficiency are critical considerations.

The TPS2115ARBT operates in three modes: OR-ing, Split Supply, and Inrush Current Limiting. In OR-ing mode, the PMIC switches between two input power sources (VDD1, VDD2) to provide power to the system and achieve maximum efficiency. In Split Supply mode, the device provides a regulated output voltage from the input power source and can also be combined with OR-ing mode to ensure redundancy. In Inrush Current Limiting mode, the PMIC limits the inrush current of the power source, which improves system and component reliability.

The TPS2115ADRBT features a low 5mΩ on-resistance MOSFET and an integrated 0.5Ω ideal diode. This low on-resistance and integrated ideal diode ensure the highest possible efficiency with no voltage dropout even when several OR-ing operations are required. The device also features over-temperature and short-circuit protection for increased reliability.The power good and fault detection logic is integrated to indicate the status of the input supply and provide system monitoring.

The TPS2115ADRBT supports a wide range of input voltage, from 4.5V to 16V, making it suitable for a wide range of OR-ing applications. The device is also highly efficient, providing up to 98% efficiency at up to 6A output current. The small 6.2mm x 5.2mm package makes it an ideal solution for low-profile and high-density applications. The device is also available in an SO-8 package for easier mounting.

The TPS2115ADRBT is an ideal solution for applications requiring efficient OR-ing operations with minimal voltage drops and high reliability. The wide range of input voltage, low on-resistance MOSFET, integrated ideal diode, and over-temperature and short-circuit protection make the device well-suited for high-density and space-restricted applications. The PMIC is well-suited for enterprise servers, storage systems, and other power management applications.
