The LTC4251IS6#TRPBF is a low voltage hot-swap controller designed to allow a card to be safely inserted and removed from a live system while providing near zero in-rush current. Its wide input voltage range allows it to provide protection for all standard hot-swap applications, from 3.3V to 55V. The LTC4251IS6#TRPBF is the ideal choice for applications ranging from 5V to 36V systems, providing full system protection for a variety of voltages and situations.
PMIC (Power Management IC) hot swap controllers are system protection ICs used to manage voltage from a single PMIC device or multiple PMIC devices. Power management ICs are integrated circuits (ICs) which enable the control of power for electronic devices. The LTC4251IS6#TRPBF hot swap controller is one kind of PMIC device and is commonly used to prevent damage to the host system when a card is inserted or removed. The hot swap controller monitors (monitors) the input voltage and the current flow to the card and limits the current when the voltage exceeds the predetermined threshold. When the voltage rises above the threshold, the controller triggers an overtemperature protection mechanism that shuts down the circuit, preventing card damage and protecting the host system.
The hot swap controller is specifically designed to work in high-power, low-voltage applications. It is equipped with a charge pump and an internal loop control architecture that improves its accuracy and response time. The hot swap controller features an on-chip voltage regulator that automatically adjusts the voltage range according to the regulated voltage range, allowing the controller to accurately regulate the amount of current going to the card. The controller also features a brownout monitor (BOM) that detects when the supply voltage drops below a certain threshold and shuts off the system.
The LTC4251IS6#TRPBF hot swap controller is widely used in consumer applications, such as personal computers, laptops and tablets, as well as embedded and industrial applications, such as avionics, medical equipment, data centers and telecommunications. The controller provides system protection for a variety of applications, from 5V to 36V systems, by limiting the current drawn from the input supply, monitoring the input voltage and triggering system shutoff when the voltage exceeds a predetermined threshold.
The LTC4251IS6#TRPBF hot swap controller is an integrated PMIC device that enables power transfer from a host device to a card in a safe and efficient manner. The controller provides system protection for a variety of voltage ranges and features an on-chip voltage regulator, charge pump and brownout monitor, providing complete control of the power management process. The controller is used in a variety of consumer, embedded and industrial applications and is the ideal choice for applications requiring low voltage hot-swap protection.
