LTC4226CMS-1#PBF

PMIC - Hot Swap Controllers

The LTC4226CMS-1#PBF is an integrated Hot Swap controller, also known as a Power Management Integrated Circuit or PMIC. This device is used in a variety of applications, from personal computer motherboards to commercial server and cloud computing installations. The LTC4226CMS-1#PBF is specifically designed for high-current circuits such as those found in many high-performance personal computers.

The Hot Swap controller is a small circuit board that regulates the voltage, current and temperature levels of a circuit. It also manages the power sequencing for controlling the turn-on and turn-off of systems. The Hot Swap controller is responsible for ensuring that the power is delivered to the system without causing excessive voltage or current fluctuations. In the case of the LTC4226CMS-1#PBF, a slew rate is monitored and adjusted, which limits the speed at which the power is applied, allowing the circuit to be safely started and shut down.

The LTC4226CMS-1#PBF is a highly integrated circuit that also provides undervoltage lockout, over-voltage protection, short-circuit protection and over-temperature protection. Additionally, the device features a user-adjustable voltage slew rate, adjustable voltage tracking and a separate open drain fault signal output. A comparator inside the Hot Swap controller monitors and adjusts the output voltage and current to ensure system safety.

To ensure safe operation, the LTC4226CMS-1#PBF includes several features, such as over-current protection, over-temperature protection, automatic disabling (after a fault) and over-voltage lockout. Additionally, the Hot Swap controller features a programmable current limit, adjustable voltage tracking and short circuit protection and current sharing capability. The Hot Swap controller also features thermal shutdown protection to reset itself if the power is too high.

In order to use the LTC4226CMS-1#PBF, the Hot Swap controller must be connected to an external dc-dc converter and a power source. The external converter powers the controller directly. The power source is connected to the Hot Swap controller using two transistors - an N-channel and a P-channel. The N-channel transistor is responsible for powering up the controller and the P-channel transistor is responsible for turning off the controller in cases of over-voltage or over-current.

The LTC4226CMS-1#PBF is used in many applications and is designed to provide maximum safety and performance. This Hot Swap controller provides reliable power and temperature regulation and is ideal for applications such as data center, cloud computing, server, industrial, consumer and other high-power applications. With its low power consumption and high efficiency, the LTC4226CMS-1#PBF is well suited to a range of high-current circuits.
