Linear Technology's LTC4260CSW#PBF Hot Swap Controller

The LTC4260CSW#PBF is a sophisticated Hot Swap controller from Linear Technology, designed to enable safe board insertion and removal from a live backplane. This integrated circuit helps to manage the inrush current experienced when a card is inserted, preventing damage to both the card and the backplane's power supply components.

Encased in a 16-lead wide body SOIC package, the LTC4260CSW#PBF offers an array of features that enhance the reliability and stability of high-availability systems. It is particularly suitable for network servers, telecom equipment, and RAID systems, where uninterrupted operation is critical.

Key Features:

• Controlled Inrush Current: The device ensures a soft start for hot-swapped boards, limiting the inrush current to prevent glitches in the supply rail, which can lead to system instability or damage.
• Adjustable Current Limit: Designers can set the current limit threshold as per the requirement of the specific application, ensuring flexibility and protection tailored to the system's needs.
• Overcurrent Protection: The LTC4260CSW#PBF features a fast acting current limit and a circuit breaker function, which helps protect both the connector and the backplane from the damaging effects of overcurrent conditions.
• High Voltage Operation: This device is capable of operating with supply voltages up to 16.5V, making it versatile for various applications.
• Power Good Output: It includes a 'power good' output that can be used to enable a downstream converter, ensuring that the load is only powered when safe operating conditions are established.
• 12-Bit ADC & I2C Interface: The LTC4260CSW#PBF features an integrated 12-bit ADC and I2C compatible interface that allows for the monitoring of voltage, current, and fault status, providing valuable diagnostic information.

The LTC4260CSW#PBF is designed with the reliability and ruggedness expected of Linear Technology products, ensuring that your systems maintain operation even in the face of hot-swap events. With its comprehensive suite of features, this Hot Swap controller is an excellent choice for managing power distribution in sensitive electronic systems.

Whether you are designing a new system or upgrading an existing one, the LTC4260CSW#PBF offers the performance and protection necessary to ensure a seamless and secure operation.
