LTC4380CDD-2#TRPBF Description

Short technical summary and product information.

The LTC4380 is a low quiescent current surge stopper from Analog Devices that protects downstream loads from high voltage transients, such as load dump in automotive systems. Overvoltage protection is achieved by clamping the gate voltage of an external N-channel MOSFET, limiting the output voltage to a safe level during surge events. The LTC4380CDD-2#TRPBF variant features a typical 31.5V gate clamp suitable for 24V/28V systems.

 

This device operates over a wide input voltage range of 4V to 72V, with a typical operating quiescent current of only 8µA, reducing to 6µA in shutdown. Overcurrent protection is also provided, and an adjustable fault timer with MOSFET stress acceleration allows safe handling of fault conditions. The gate driver supports back-to-back MOSFETs for reverse input protection down to -60V.

 

AEC-Q100 qualified for automotive applications, the LTC4380 is well-suited for automotive load dump, avionic surge protection, hot swap, and battery-powered high-side switching. It is offered in a compact 10-lead WFDFN with exposed pad (3mm × 3mm DFN package) for surface mount assembly.
