The LTC4365HDDB#TRPBF is a Dual-Channel Hot Swap Controller with Power Control, Undervoltage Lockout, Back-Drive Protection and an I2C Compatible Hot Swap Controller. It is an integrated power management IC for hot swap applications, providing dual-channel hot swap control and protection for dual-channel POLs and DC/DC converters. It is designed for applications such as high density servers, rack-mounted systems, switching power supplies, and telecom equipment. The LTC4365HDDB#TRPBF utilizes an integrated dual-channel Hot Swap controller, combined with power control logic and Undervoltage Lockout (UVLO) and backdriving protection for device isolation and protection. It is well suited for applications in which two separate power supply devices are connected in a specific channel configuration, like a redundant power architecture. The LTC4365HDDB#TRPBF is a dual-channel power control IC with power protection and digital control circuit. The power control circuit includes: Dual channel Voltage Comparator, Dual Channel Over Voltage/Under Voltage Comparator and single channel Disable Comparator. The digital control circuit includes an I2C compatible Hot Swap controller and 2 programmable voltage reference blocks.

The LTC4365HDDB#TRPBF controller provides user-configurable digital control and protection of two power supply devices. It offers on-chip over-/undervoltage, back-driving protection, and thermal protection of the load devices. The dual channel Hot Swap controller provides dual independent power control, allowing redundant power supply device operation with individual enable control and protection. With its integrated dual channel Hot Swap controller, the controller is suitable for controlling a variety of redundant power configurations. The voltage comparator can detect and measure the output voltage of two power supply devices, and allows for backdrivable protection of the two devices, making sure the two power supply devices are presenting the expected output voltage.

The LTC4365HDDB#TRPBF also provides source select control when the dual supply devices are enabled and active, which allows the user to select which power supply device supplies power to the load. This feature is especially useful when one power supply device fails, and it is necessary to switch to the alternate device. The controller also allows for "break-before-make" switching, which eliminates any potential momentary degradation of the load. Additionally, the controller also offers thermal protection of the load devices, ensuring that the two power supply devices operate within their specified temperature ranges.

The LTC4365HDDB#TRPBF is an integrated power management IC that is well suited for applications requiring enhanced power supply device control and protection. By providing hot swap control and protection, the LTC4365HDDB#TRPBF enables greater system reliability and is well-suited for high performance, redundant, dual supply designs. Additionally, the integrated I2C compatible Hot Swap controller and programmable voltage reference blocks make the LTC4365HDDB#TRPBF an ideal choice for Hot Swap and power supply applications.
