The is a low quiescent current surge stopper in 10 pin DFN package. This low quiescent current surge stopper protects loads from high voltage transients. Overvoltage protection is provided by clamping the gate voltage of an external N-channel MOSFET to limit output voltage to a safe value during overvoltage events such as load dump in automobiles. An internal multiplier generates a TMR pin current proportional to VDS and ID, so that operating time in both overcurrent and overvoltage conditions is limited in accordance with MOSFET stress. The GATE pin can drive back to back MOSFETs for reverse input protection, eliminating the voltage drop and dissipation of a schottky diode solution. It is used in hot swap/ live insertion, high side switch for battery powered systems and intrinsic safety applications.
