Surge Suppression ICs are specially designed to protect sensitive equipment against the damaging effects of electrical surges or transients. The LTC4380IMS-3#PBF is a multi-channel, bidirectional surge protection IC that is optimized for high-performance automotive and industrial applications. It is capable of detecting and limiting potentially damaging voltage transients on two power supply lines with complementary lines, while also providing bidirectional current protection for large capacitor banks.The LTC4380IMS-3#PBF features two independent channels, each featuring a low-impedance MOSFET to limit transient over-voltage and an operational amplifier to detect over-current. The MOSFETs are configured to limit the voltage rise during a surge event, as well as to act as a clamp that prevents the voltage from falling below a specified threshold. In addition, the bi-directional current protection feature protects against large short-duration current surges by detecting the voltage across the current sense resistor and quickly activating the current limiting mechanism.The LTC4380IMS-3#PBF is designed for a wide range of automotive and industrial applications, including automotive EMC immunity, HVAC, lighting, power supplies, and industrial controllers. It is also suitable for applications requiring power surge protection such as power strips and smart plugs. The device features a wide operating voltage range (6.5V to 18V) and a minimum operating temperature range of -40°C, making it suitable for a range of harsh environment applications.The LTC4380IMS-3#PBF is a low-profile, industry standard 8-pin dual in-line package (DIP) and is fully RoHS compliant. The device offers a robust supply voltage protection level of up to 500W/ms maximum peak pulse current (Ipp) and surge stopper operation upfield to 48V. It also provides a low output offset voltage of 1mV and an over-voltage trip point of 5V, providing reliable protection from over-voltage surges.In summary, the LTC4380IMS-3#PBF is a multi-channel, bidirectional surge protection IC optimized for automotive and industrial applications. It offers a wide operating voltage range and low profile design, while providing robust transient voltage protection and bidirectional current protection for large capacitor banks.
