Floating Surge Stopper Provides Unlimited Overvoltage Protection

Protecting sensitive electronic circuitry from voltage transients is an essential part of any system be it automotive, industrial, avionics or even battery-powered consumer applications. Linear Technology offers a wide variety of solutions for these applications with its surge stopper family. The LTC®4366 is the new exciting member of this surge stopper family. The LTC4366 is a high voltage surge stopper with a floating topology which allows it to suppress voltage transients far exceeding its ABS max ratings. Dual shunt regulators allow the part to float up with the supply and suppress transients at a user defined level. The voltage is regulated with the help of an external MOSFET which is controlled by the LTC4366. The operating voltage can literally be thousands of volts with the only limitation being the safe operating area (SOA) of the MOSFET used in conjunction with the part. Once the output reaches the clamp voltage a timer runs. Once the timer expires the LTC4366 turns the MOSFET off. The timer and clamp voltage are adjustable, allowing full flexibility to the user. During operation, the entire circuit consumes only a few milliamperes. The device may be shut down to less than 20µA making it an ideal solution for the power conscious. High voltage applications include protecting from motor transients, coupled overvoltage, incorrect input supplies or power supply failures. While traditional protection circuitry relies on bulky inductors, capacitors, fuses and transient voltage suppressors to clamp the transient, the LTC4366 protects by series regulating the transient. It is packaged in a tiny 8-lead TSOT-23 and 3mm x 2mm DFN packages.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
