The TPS2391DGK is a high performance power management device designed specifically for hot swap applications. It is designed to provide regulated power supply and effective current limiting for circuits with a wide range of supply voltages and power levels. The TPS2391DGK provides protection against over-current, over-voltage, under-current, and reverse-current events, and supports both single-rail and multi-rail applications. The device’s ultra-low power consumption makes it ideal for use in portable applications.

The TPS2391DGK is a member of Texas Instruments’’ Hot Swap Controllers. This family of power management devices is designed to provide reliable power supply and effective current limiting when circuit supply voltages and power levels vary. It provides dependable circuit protection and fault isolation functions in applications that require hot swapping.

The TPS2391DGK is perfect for use in applications such as: embedded systems, power sources, hot swap devices like DIMMs, storage systems, server applications and other systems that require reliable power supplies and efficient current limiting.

The TPS2391DGK is designed to monitor the output voltage and limits the current flow through the external power switch by disabling or enabling its internal driver transistor. It is capable of detecting an operating range of voltages (3.3V to 8V) and current levels (100 mV - 2A). The device also has an adjustable over-voltage and under-voltage threshold which allows greater control of the sensing and triggering points of the current limiting circuit.

The TPS2391DGK features a number of features to ensure the circuit’s protection during hot swap operations. It has overtemperature protection and short-circuit protection to protect against unexpected over-heating and electrical events. It also provides a power good indication to inform the host system that the power supply is within acceptable operating parameters and it also supports over-current and under-current fault indication.

The TPS2391DGK is also designed to be thermal shutdown-proof, which guarantees a safe minimum current limit for the load. It also helps to protect the load in the event of a very high load current spike. The device also supports a high-impedance mode, which allows higher characterization times while minimizing power consumption and protecting loads from discharging at high currents.

In summary, the TPS2391DGK is a power management device specifically designed for hot swap applications. It is perfect for embedded systems, power sources, hot swap devices like DIMMs, storage systems, server applications and other systems that require reliable power supplies and efficient current limiting. It provides protection against over-voltage, under-voltage, reverse-voltage, over-current, and short-circuit events. The TPS2391DGK also supports thermal shutdown-proof mode, high-impedance mode and power good indication, providing reliable power supply and effective current limiting for circuits with a wide range of supply voltages and power levels.
