The STMPS2252MTR is a high-power intelligent power distribution switch by STMicroelectronics located within the PMIC - Power Distribution Switches, Load Drivers family. This device is designed for applications that require both power-sharing and load-switching functions in a single package.

Designers can program the STMPS2252MTR through a flexible serial interface to optimize the behavior of the circuit within their system to fit the needs of their application. With graphical tools, including SmartDrvStudio, users can rapidly configure and simulate the performance of their circuit. Finally, this device uses low profiles for applications that require a smaller footprint.

The device consists of one power input connection and two paired output channels, each of which can control either a single load or, in an ideal configuration, two separate loads that need local power distribution. The built-in isolator allows the two output channels to function independently of each other while still providing power to both. The two channels can be configured and programmed to operate in three distinct modes: parallel with synchronous and asynchronous modes, series with synchronous and asynchronous modes, and bridge mode. The status and control signals allow engineers to manage the device\'s power management and sequencing.

The STMPS2252MTR supports wide input voltage and load current range, with a maximum VIN of 55 V and a maximum load current of 2.5 A. This device also features accurate current sensing on the load channel with a measurable dynamic range of up to 102 mA RMS, making it ideal for high-current applications. The on-board temperature sensor monitors junction temperature, allowing the device to protect itself against thermal overloads. Additionally, the device provides the necessary diagnostics to ensure the reliability and longevity of the system by providing real-time thermal and over-current monitoring.

The STMPS2252MTR intelligent power distribution switch complements the extended range of products available for high-power applications. Engineers can design and build a feature-rich power management system, customizing the parameters to match the system\'s needs and ensuring reliable performance, even in high-power applications.
