TPS2399DGKR

PMIC, or Power Management Integrated Circuits, are a type of electronics used for the management and optimization of the power supply and components of an electrical system. Hot Swap Controllers are a subset of this circuitry and are used to safely disconnect and add power to a system without affecting the current state. The TPS2399 DGKR is an advanced hot swap controller IC that provides system designers with a reliable and robust power control solution that can be used in a variety of applications.

TPS2399DGKR Application Field and Working Principle

The TPS2399 DGKR hot swap controller is designed for use in server, industrial, and networking applications. It can also be used in communications and automotive systems, as well as in battery powered and portable electronic devices. The TPS2399 DGKR hot swap controller is designed for use in applications where power sequencing and hot plugging is required and is especially useful for high-reliability, system-level protection.

The TPS2399 DGKR hot swap controller is an advanced IC that provides system designers with a reliable and robust power control solution. It consists of an integrated N-channel MOSFET switch and several control, protection and logic logic components. The MOSFET switch features an integrated P-channel Boost Diode that allows the switch to remain active even when the input voltage drops below zero volts or the output is shorted. This makes the TPS2399 DGKR ideal for applications that require continuous hot swap or power sequencing operations, such as servers, networking, industrial and communications systems.

The hot swap control logic consists of an OVLO comparator, an OVU comparator and an open collector output for logic control of the MOSFET switch. The OVLO comparator is used to detect an undervoltage condition and can be set to trip at any desired voltage level. The OVU comparator is used to detect an overvoltage condition and can also be set to trip at any desired voltage level. The output of the OVU comparator is open drain output that can be used to enable or disable the MOSFET switch. This allows for power sequencing and hot plugging operations in which the enable logic is used to control the enable/disable of the MOSFET switch.

The TPS2399 DGKR hot swap controller also includes several protection features. These include reverse voltage protection, overcurrent protection, undervoltage lockout, thermal shutdown and overtemperature protection. The reverse voltage protection ensures that the device will turn off if a negative voltage is applied to the input. The overcurrent protection will shut off the MOSFET switch if the current exceeds a defined threshold. The UVLO comparator on the TPS2399 DGKR is used to detect low-voltage conditions, and the MOSFET switch will turn off if the input voltage is below a defined threshold. The thermal shutdown and overtemperature protection ensure that the MOSFET switch will remain off if the temperature exceeds a certain limit.

The TPS2399 DGKR hot swap controller is a versatile and reliable power management IC that provides robust protection and control for a variety of applications. It is designed to provide system level protection against power sequencing and hot plugging operations, and is especially useful for high-reliability applications. The integrated protection features make the TPS2399 DGKR a reliable and safe option for controlling power in a variety of systems. It is an ideal choice for server, industrial, networking, automotive, communications and portable electronics applications.
