The TPS25944ARVCR is a Hot Swap controller. It is an integrated circuit (IC) that can be used to detect and control the powering of any DC device. The Hot Swap controller is a type of power management integrated circuit (PMIC) that can provide an efficient, safe, and reliable way to power and protect any system. The TPS25944ARVCR provides charging and power management for portable electronic systems that may use various power sources. The TPS25944ARVCR provides constant current/voltage batteries and delivers a constant level of current to the battery while monitoring the temperature and internal voltage of the battery.The TPS25944ARVCR is designed for Hot Swap applications and is ideal for use in systems such as power over Ethernet (PoE) devices, smart home and automation applications. The IC utilizes a voltage-mode controller and a high-bandwidth current sensor to ensure power is correctly supplied and managed for system loads.The Hot Swap controller can detect when an insertion has occurred, initiate and control a regulated power supply starting from a battery or a current-limited supply, adjust the regulated power dynamic load current and automatically disconnect the load in case of an overcurrent/overvoltage/overtemperature or external circuit fault. The fault thresholds and set-points of the Hot Swap controller can be configured using external resistors.The TPS25944ARVCR is also equipped with resistive thermal and current foldback protection, programmable soft start, undervoltage lockout, temperature compensation, and output disconnect. The operating temperature range of the Hot Swap controller is -40 C to +125 C.Overall, the TPS25944ARVCR Hot Swap Controller is a critical component in protecting stackable and powered devices in various electronic systems and can greatly improve system reliability and safety. The Hot Swap controller can be used in a wide range of applications including smartphones, embedded systems, connected devices, industrial automation, server and storage systems and much more.
