Product Overview: LTC1921CS8#PBF

The LTC1921CS8#PBF is a high-performance, dual-channel hot swap controller designed by Linear Technology, now part of Analog Devices, to ensure safe board insertion and removal from live backplanes. This sophisticated component is housed in an 8-lead SO package, engineered to protect electronic systems by controlling the inrush current when a card is inserted into a live power supply.

Key Features

• Integrated Dual Channel: The LTC1921CS8#PBF features two independent channels that allow for the simultaneous control of two separate supply voltages, making it an ideal choice for complex systems requiring multiple power domains.
• Adjustable Inrush Current Control: Users can tailor the inrush current to their specific application needs, ensuring a smooth power-up sequence and reducing the risk of damage to sensitive components.
• Overcurrent Protection: The device includes robust overcurrent protection, which safeguards the circuitry from excessive currents that could potentially cause overheating or failure.
• Power Good Outputs: Each channel has a 'power good' output signal that indicates when the output voltage is within the acceptable range, providing a reliable status indicator for system monitoring.

Applications

The LTC1921CS8#PBF is versatile and can be used in a wide range of applications, including:

• Server and Telecom Hot Swap Applications
• Redundant Power Supplies
• Industrial Systems
• Network Routers and Switches
