TPS2231PWPR Description

The TPS2231PWPR is a high-side power switch designed for ExpressCard™ applications, offering robust performance and reliability. Manufactured by Texas Instruments, this power management IC (PMIC) is part of the Power Management category and is housed in a 24HTSSOP package. The device features a maximum output current of 1.3A and a typical on-resistance (Rds On) of 45mOhm, ensuring efficient power delivery and minimal power loss. The TPS2231PWPR operates with a 1:1 input-to-output ratio, supporting load voltages of 1.5V and 3.3V, making it suitable for a wide range of applications requiring precise voltage control.

TPS2231PWPR Features

The TPS2231PWPR includes several unique features that enhance its functionality and reliability. It offers a "Power Good" and "Status Flag" feature, which provides real-time monitoring and status indication of the power supply. This ensures that the system can detect and respond to power anomalies promptly. The device also includes fixed current limiting and over-temperature fault protection, safeguarding against overcurrent and thermal issues that could damage the system.

The TPS2231PWPR is designed for surface mount applications, making it ideal for compact and high-density PCB designs. It is REACH unaffected and RoHS3 compliant, ensuring it meets stringent environmental and safety standards. The moisture sensitivity level (MSL) of 2 (1 Year) makes it suitable for a variety of manufacturing environments, while the ECCN classification of EAR99 simplifies export compliance.

TPS2231PWPR Applications

The TPS2231PWPR is particularly well-suited for applications requiring high-side power switching, such as ExpressCard™ interfaces, where it can manage power efficiently and safely. Its ability to handle multiple outputs (up to three) makes it versatile for systems with multiple power rails. The device's low Rds On and precise voltage control make it ideal for applications where power efficiency and reliability are critical, such as in portable devices, laptops, and other consumer electronics.
