Product Summary

The LMD18400N is a fully protected quad high side driver. The LMD18400N contains four common-drain DMOS N-channel power switches, each capable of switching a continuous 1 Amp load (>3 Amps transient) to a common positive power supply.

Parametrics

LMD18400N absolute maximum ratings: (1)Supply Survival Voltage (Pin 20) Transient (t = 10 ms): 80V; (2)Supply Survival Voltage (Pin 20) Continuous: -0.5V to +60V; (3)Output Transient Current (Each Switch): 3.75A; (4)Output Transient Current (Total, All Switches): 6A; (5)Output Steady State Current (Each Switch): 1A; (6)Power Dissipation: 5W; (7)Junction Temperature: 150℃; (8)Storage Temperature Range: -65℃ to +150℃; (9)Lead Temperature (Soldering, 10 sec.): +260℃.

Features

LMD18400N features: (1)Four independent outputs with >3A peak, 1A continuous current capability; (2)1.3Ω maximum ON resistance over temperature; (3)True instantaneous power limit for each switch; (4)High survival voltage (60 VDC, 80V transient); (5)Shorted load (to ground and supply) protection; (6)Overvoltage shutdown at VCC > 35V; (7)LS TTL/CMOS compatible logic inputs and outputs; (8)<10 μA supply current in "sleep" mode; (9)-5V output clamp for discharging inductive loads.
