Product Overview: LTC4223CDHD-2#PBF

The LTC4223CDHD-2#PBF is a sophisticated dual Hot Swap™ controller designed by Linear Technology to enable safe board insertion and removal from live backplanes. It is a highly integrated solution that provides power management and protection for systems with dual supplies. This component is specifically engineered to protect low power boards and is housed in a compact 16-lead DFN package, which is ideal for space-constrained applications.

Key Features

• Independent Control: It features two independent channels, each capable of controlling an n-channel MOSFET for power supply ranging from 2.9V to 15V. This allows for the management of two separate power rails within a single device.
• Adjustable Current Limit: The LTC4223CDHD-2#PBF provides an adjustable overcurrent limit, which can be set by a single external resistor per channel, ensuring that the power supply operates within safe current boundaries.
• Fast Overcurrent Fault Response: With a fast response time to overcurrent faults, this device helps to prevent damage to the electronic components by quickly disconnecting the faulty load from the power supply.
• Power Good Outputs: Each channel has a power good output that indicates when the output voltage is within the acceptable range, providing a reliable status indication for system monitoring.
• Under-Voltage and Over-Voltage Protection: The controller includes under-voltage and over-voltage lockout features that ensure the power rails are within the specified voltage range for safe operation.

Applications

The LTC4223CDHD-2#PBF is versatile and can be used in a variety of applications, including:

• RAID Systems
• Network Servers
• Telecommunications Equipment
