DESCRIPTION
The LTC®4380 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 the output voltage to a safe
value during overvoltage events such as load dump in
automobiles. Fixed gate clamp voltages are selectable for
12V and 24V/28V systems. For systems of any voltage up
to 72V, use the adjustable gate clamp versions. Overcur-
rent protection is also provided.
An internal multiplier generates a TMR pin current pro-
portional to VDS and ID, so that operating time in both
overcurrent and overvoltage conditions is limited in ac-
cordance with MOSFET stress.
The GATE pin can drive back-to-back MOSFETs for reverse
input protection, eliminating the voltage drop and dissi-
pation of a Schottky diode solution. A low 8µA operating
current permits use in always-on and battery powered
applications. An accurate ON pin comparator monitors
the input supply for undervoltage (UV) conditions and
also serves as a shutdown input, reducing the quiescent
current to 6µA.
