FAQs

What is LTC4376IDHD#PBF?

The LTC4376IDHD#PBF is a hot swap controller designed by Linear Technology (now part of Analog Devices). It is used to safely hot swap (insertion or removal of a component from a live backplane) circuit boards in high availability systems while protecting both the load and the backplane from damaging current and voltage spikes.

How Does LTC4376IDHD#PBF Work?

The LTC4376IDHD#PBF works by monitoring the voltage across a current sensing resistor in series with the supply line. When a fault or overload condition is detected, the controller quickly turns off an external N-channel MOSFET to limit the current and protect the system. It also features adjustable undervoltage and overvoltage lockout thresholds for robust and reliable operation.

How Many Pins does LTC4376IDHD#PBF have and What are the Functions of the Pinout Configuration?

The LTC4376IDHD#PBF is housed in a 16-pin QFN (Quad Flat No-Lead) package. The pinout configuration includes:

VIN: Positive input supply voltage pin.
VOUT: Output voltage pin to the load.
IMON: Current monitor output pin.
UV: Undervoltage lockout pin.
OV: Overvoltage lockout pin.
FAULT: Fault indicator output pin.
GATE: Gate driver output pin for an external N-channel MOSFET.

What are the Pros and Cons of LTC4376IDHD#PBF?

Pros:

Hot Swap Capability: Safely hot swaps components in live systems without causing damage.
Overcurrent Protection: Provides robust protection against overcurrent situations.
Adjustable Thresholds: Allows customization of undervoltage and overvoltage lockout settings for specific applications.
Compact Package: Housed in a space-saving QFN package for efficient PCB layout.

Cons:

Complexity: Requires careful consideration of system requirements for optimal setup and operation.
External Components: May require additional components such as MOSFETs and resistors for complete functionality.

Are There Any Equivalents/Alternatives to LTC4376IDHD#PBF for Recommendation?

The LTC1643 from Linear Technology (Analog Devices) is a similar hot swap controller with different features.
Alternatives to the LTC4376IDHD#PBF include the MAX5941 from Maxim Integrated and the TPS24710 from Texas Instruments.
