The TPS25942ARVCR is a single-channel ideal diode hot swap controller device from Texas Instruments. It provides over-current protection and fault interrupt for a high power rail or board power supply. This device is an integrated PMIC hot swap controller that allows the rail to be safely inserted and removed from a live system. In addition to protection functions, the TPS25942ARVCR runs a low-power MCU. The primary application of this device is to provide an ideal diode-style hot swap function as well as fault indicators for a range of applications, from consumer to industrial/automotive.

The TPS25942ARVCR provides over-current protection against extremely large in-rush currents. It has a maximum sense voltage of 45 V and a threshold voltage of 13 V. Its output current limit is adjustable up to 20 V. It has an internal current-limit threshold of 150 mV typical and 400 mV maximum. It provides an adjustable OCP threshold over the range of 130 mV to 600 mV, and also has a temperature sense pin.

The device has an integrated open drain fault signaling output. The fault signal is used to notify a host processor of an overload condition. The TPS25942ARVCR supports adjustable fault thresholds for over-current protection and junction temperature sensing. The thermal external diode is used for a direct measurement of thermal changes in the system. The device has a minimum required ambient temperature of -40°C and a maximum junction temperature of +150°C.

The TPS25942ARVCR has a microcontroller core with two instruction sets. These various instruction sets can be used for programming and for setting user-defined parameters for the device. The integrated MCU can also be used to monitor line voltage, current, and temperature values. An of the device\'s registers can be programmed with specific thresholds, allowing the device to function at user-defined levels that can be changed over time to accommodate system requirements.

The TPS25942ARVCR ideal diode hot swap controller can be used to provide automated protection in a wide range of applications. It can be used to hot-swap a board without damaging components or causing system instability. It can be used in power grids and systems for fault protection, as well as sensor protection. It is also suitable for use in computer and telecom backplanes, industrial motor power systems, and other industrial equipment.

The TPS25942ARVCR provides precision current, voltage, and temperature measurement, allowing it to shut down the system in the case of an over-current load or sudden change in temperature. The integrated MCU can monitor and respond to changes in the system and adjust the device\'s parameters accordingly. The device also ensures a safe and reliable start-up, ensuring the system remains stable while providing the necessary protection.
