Introduction

AI Translation

The LTC4381 is an integrated solution for low quiescent current eFuse with an internal 9mΩ N-Channel MOSFET. Overvoltage protection is provided by clamping the gate voltage of an internal 9mΩ N-channel MOSFET to limit the output voltage to a safe value during overvoltage events such as load dump in automobiles. The MOSFET safe operating area is production tested and guaranteed for the stresses during high voltage transients. Fixed output clamp voltages are selectable for 12V and 24/28V systems. For systems of any voltage up to 80V, use the adjustable clamp versions. Overcurrent protection is also provided. 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. A low 6µA operating current permits use in always-on and battery powered applications.
