The TPS24770RGER is a hot-swap controller from Texas Instruments. It is specifically designed to manage system power across multiple domains. It is designed to manage the power coming from multiple domains and power sources and to balance the output current delivered to each domain. As a result, this device helps to ensure the reliable operation of the connected system.

The device contains two integrated hot-swap controllers, one for each domain. Each controller independently monitors and controls its respective domain power, driving an external NMOS to control the current delivery to the system via the external voltage rail. This ensures that the power source and the power rail receive appropriate power levels and that the connected system components are protected from over-voltage or over-current conditions.

The device also includes an advanced fault detection and protection feature set, providing the user with a high level of system reliability. The device provides an overtemperature detection, allowing the system to shut down if temperatures become dangerously high. The device also features over-current, over-voltage, and inrush current limiting features, all of which protect the system from possible damage due to current spikes or over-voltage situations.

The device is designed to enable full system power sequencing control. The device includes an output voltage sequencing feature that allows the user to program the output voltage to switch on or off in the sequence of user choice. This feature is especially useful for multi-rail applications, where the system needs to ensure that all rails are switched on in a predefined sequence. This ensures that all system components receive their necessary power levels in the correct order.

In addition, the device also features a programmable input voltage monitoring feature. This feature allows the user to monitor the input voltage levels and to take corrective action if the voltage deviates from its predefined levels. This ensures that the system remains operational within its operational limits, preventing it from being subjected to over-voltage or under-voltage conditions.

The TPS24770RGER is packaged in a thermally enhanced 32-pin QFN package and is designed to operate over a wide temperature range. This device is ideal for use in applications that require hot-swap controllers to closely monitor and control the power flow to multiple power domains.
