LTC7862IFE#PBF, Switching Surge Stopper Automotive 20-Pin TSSOP EP Tube

LTC7862 is an efficiency switching surge stopper. It protects loads from high voltage transients. High efficiency switching allows high output currents, small solution sizes, and high reliability. During an input overvoltage event, this device controls the gates of two external N-channel MOSFETs to act as a switching DC/DC step-down regulator. This maintains the output voltage at a safe value, allowing the loads to continue to operate through the input overvoltage event. During normal operation, this device turns on the top external N-channel MOSFET continuously, passing the input voltage through to the output, with minimal voltage drop. Using a fast peak current comparator, this device also limits the maximum output current to protect against overcurrent and short-circuit faults. It is widely used in application such as automotive/avionic/industrial surge protection, automotive load dump protection, vehicle power including ISO7637, military power including MIL1275 etc.
