Description

LTC4264CDE Negative Voltage Hot Swap™ Controller

The LTC4264CDE from Linear Technology is a sophisticated negative voltage Hot Swap controller designed to enable safe board insertion and extraction from a live backplane. Housed in a compact 12-lead DFN package (4mm x 3mm), this controller is specifically engineered to handle negative supply voltages ranging from -9V to -80V.

The core functionality of the LTC4264CDE revolves around its ability to control the gate voltage of an external N-channel MOSFET to gently power up capacitive loads, thereby reducing the inrush current and preventing any potential damage to the circuit components. Its overcurrent function is activated if the load current exceeds a user-defined threshold, ensuring the system's protection against short-circuit and overcurrent conditions.

One of the standout features of this product is its adjustable current limit, which allows users to set the maximum current their system can draw. This flexibility is crucial for systems with varying load requirements. Additionally, the LTC4264CDE provides a circuit breaker function, which uses a timer to determine fault conditions, and an automatic retry feature that can be programmed by the user.

The device also includes a UV (undervoltage) lockout feature, ensuring that the Hot Swap operation does not commence until the supply voltage reaches an acceptable level. This prevents the system from operating under potentially harmful conditions. Furthermore, the LTC4264CDE offers an adjustable supply UV threshold and hysteresis to accommodate different system requirements.

For status reporting, the LTC4264CDE incorporates a fault output that signals when the MOSFET is off due to either an overcurrent event or an undervoltage condition. This feature allows for easy monitoring and diagnosis of system health and performance issues.

Designed for rugged environments, the LTC4264CDE is specified over the commercial and industrial temperature ranges, making it suitable for a wide array of applications, including telecom/networking equipment, servers, and industrial systems where reliable negative voltage power distribution is critical.

With its combination of advanced protection features and programmable parameters, the LTC4264CDE is an essential component for managing power in high-availability systems and ensuring the longevity and reliability of electronic equipment.
