New over voltage protection controller from Linear

Linear Technology has introduced the LT4363, a new overvoltage protection controller that provides overvoltage and overcurrent protection to high-availability electronic systems. Supply voltages surge whenever currents flowing through long inductive power buses change abruptly and automotive batteries can experience a condition that is known as load-dump, where the voltage can stay elevated for many milliseconds.
