LTC4380IMS-2#TRPBF

Analog Devices · Surge Protection Devices (SPDs) · MSOP-10

LTC4380IMS-2#TRPBF from Analog Devices, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DRN input External MOSFET drain-source voltage sense input; DRN current (maximum 2.5mA) multiplied with ΔVSNS to produce TMR current proportional to MOSFET power dissipation, voltage range -0.3V to 53V.
2 VCC power_in Positive supply voltage input for 4V to 80V normal operation; withstands -60V to 80V absolute maximum including reverse battery conditions to 60V below ground.
3 GATE output N-channel MOSFET gate drive output regulated to 11.5V above OUT pin; internally clamped to 31.5V (SEL=GND) or 50V (SEL=VCC) to limit output during overvoltage, voltage range -0.3V to 53V.
4 SNS input Current sense input terminal with 50mV limit threshold (62mV when OUT<1.5V); ΔVSNS (SNS-OUT) limited to ±5V, voltage range -0.3V to 53V.
5 OUT input Output voltage sense input at current sense resistor output terminal; internal 17V clamp limits GATE-OUT voltage; requires minimum 22µF bypass capacitor, voltage range -0.3V to 53V.
6 SEL input Gate clamp voltage select for LTC4380-2 fixed-clamp version; connect to GND for 31.5V internal clamp or to VCC/OUT for 50V internal clamp, voltage range -60V to 80V.
7 FLT output Open-drain fault logic output that pulls low when TMR reaches 1.215V threshold indicating overvoltage or overcurrent condition; capable of sinking up to 3mA, voltage range -0.3V to 80V.
8 GND power_in Device ground reference.
9 ON input Turn-on control input with 1.05V rising threshold for normal enable and shutdown below threshold for 6µA quiescent current mode; withstands ±60V input excursion.
10 TMR bidirectional Fault timer node for external capacitor (10V minimum X7R type recommended); internal current sources charge to 1.215V at rate proportional to MOSFET power dissipation to trigger fault; cool-down cycling before reset threshold at 100mV, voltage range -0.3V to 5V.
