The LTC4260IUH#PBF is a feature-rich Hot Swap Controller from Linear Technology. It is specifically designed for control, protection, and monitoring in high-power applications. The device provides built-in features such as redundancy, programmable delay, supply sequencing and protection for electrostatic discharge (ESD) and input transient protection. This makes the LTC4260IUH#PBF ideal for applications such as server and communications boards, enterprise blade servers, storage systems, and storage area network components.
The LTC4260IUH#PBF is configured to provide power monitoring and control to Hot Swap systems. The device has two INPUT pins, a STAT pin and two CONTROL pins, all of which can be used to monitor temperature, current, voltage, and input power to detect over- and under-voltage conditions. The device also has several protection features, such as ESD and input transient protection, thermal high and low trip points, and a programmable delay that can be used to adjust the power-up and power-down cycle times. The LTC4260IUH#PBF can provide control and monitoring for up to 256 hot-swap channels.
The LTC4260IUH#PBF also features an external temperature monitoring window, which allows it to detect temperature out of range for the hot-swap system. This helps keep the system within a safe operating temperature range. Additionally, the device has integrated voltage and current monitoring, allowing the system to be monitored for over- and under-voltage conditions. The device also has an open standard request pin, allowing direct communication with the system management bus (SMBus) or other power management software.
In terms of operation, the LTC4260IUH#PBF is configured to detect power-up and power-down commands, as well as monitoring for fault conditions. Whenever the voltage or current is out of range, or an over-temperature condition is detected, the device will act to ensure safe operation of the system. It will either shut off power to the hot-swap channel or enact other protection measures. The device also has an adjustable six-stage power-up/power-down delay that can be used to ensure the system is powered on or off in the correct order and timing.
The LTC4260IUH#PBF is designed to provide maximum Hot Swap protection and monitoring. It is a feature-rich, easy-to-configure device that can be used in a variety of high-power applications. It provides protection and monitoring for up to 256 hot-swap channels, making it an ideal choice for server and communications boards, enterprise blade servers, storage systems, and storage area network components. The device also protects against ESD, input transient protection, and thermal high and low trip points, further increasing its value.
