LTC4219IDHC-12#PBF - Hot Swap Controller from Linear Technology

The LTC4219IDHC-12#PBF is a sophisticated Hot Swap controller designed by Linear Technology to allow safe board insertion and removal from a live backplane. This integrated circuit (IC) is housed in a compact DHC package and is engineered to control the inrush current, thus preventing glitches on the power line that can affect neighboring circuits and cause system instability.

Key Features

• 12V Operation: Optimized for systems with a nominal 12V supply, the LTC4219 provides precise control over the power delivery to the loads.
• Adjustable Current Limit: Users can set the current limit threshold through an external resistor, allowing for tailored protection based on specific application requirements.
• Overcurrent Protection: The device offers a fast response to overcurrent conditions, ensuring reliable protection for sensitive components.
• Automatic Retry or Latch Off: After a fault, the LTC4219 can be configured to either attempt a power-on retry or latch off, providing flexibility in handling system errors.
• Under-Voltage and Over-Voltage Protection: These features safeguard the system from voltage transients and maintain operation within safe voltage levels.
• Power Good Output: This output signal indicates when the output voltage is within the acceptable range, enabling downstream load enablement at the right time.
• Compact DHC Package: The small footprint of the DHC package makes it suitable for space-constrained applications.
