PMIC - Hot Swap Controllers

The TPS2398DGKR is a hot swap controller designed to assist in safely bringing electronic equipment online. Hot swap controllers provide a direct current or even voltage-controlled connection between a power supply and a load, which allows for a smoother, more reliable, and less power-abrupt power transition for the connected electronics. Hot swap controllers are used in a variety of applications, including automotive electronics, medical devices, industrial equipment, computer peripherals, and power supply systems.

The TPS2398DGKR hot swap controller is designed to protect against both overvoltage and overcurrent conditions and provide load current monitoring. It features an adjustable current-limit threshold to accommodate changing wattage and current-limited output conditions. The adjustable thermal shutdown temperature range of 140°C (284°F) to 175°C (347°F) allows for a safe end-of-life shutdown. Additionally, the advanced output current limiter controls stable high current in a robust manner. A built-in loop amplifier with DC precision discharge resistor supports active load current control and load ramping.

The TPS2398DGKR can be used in a wide variety of applications, from portable electronics to industrial automation systems. Its adjustable power-on and power-off sequence provides adjustable protection against inrush current, which helps protect external circuitry and peripheral components. Additionally, the hot swap controller supports a bypass operation mode, which can be used for powering on devices that have high inrush current requirements and need to penetrate the controller\'s current limit for power-on. This bypass operation mode provides adjustable delay time and precise current limit during power-off.

In addition to its automated power cycling, the TPS2398DGKR also provides a precise active current regulation that helps manage load current to maintain stable output voltage and current. This active regulation allows the controller to anticipate and respond to changing system conditions on the fly. This feature is especially useful for precise applications such as medical equipment, which require precision current and voltage management.

The TPS2398DGKR hot swap controller offers an integrated power-fail detect and reset circuit that triggers a reset signal when the input voltage level drops below a certain level. The reset signal can be used to provide a reset signal to other circuits within the system. This feature helps ensure that the system is able to recover from device failure in a safe and reliable manner. Additionally, the hot swap controller also provides power-good output signal and over-temperature protection that helps provide reliable and robust system operation.

The TPS2398DGKR hot swap controller is designed for use in applications that require reliable and efficient power management. Its adjustable power-on and power-off sequence, active current regulation, and integrated reset and power-fail detect circuits provide reliable and robust system operation. Additionally, its bypass operation mode and precision active current regulation provide precise control over the connected circuitry. This makes the TPS2398DGKR an ideal choice for applications requiring precise and robust power management.
