LMD18400N/NOPB Product Details

The LMD18400N/NOPB is a quad fully-protected High Side Driver for use with relay and solenoid drivers. It contains four common-drain DMOS N-channel power switches, each capable of switching a continuous 1A load (>3A transient) to a common positive power supply. The switches are fully protected from excessive voltage, current and temperature. An instantaneous power sensing circuit calculates the product of the voltage across and the current through each DMOS switch and limits the power to a safe level. The device can be disabled to produce a sleep condition reducing the supply current to less than 10µA. Separate on/off control of each switch is provided through standard LSTLL/CMOS logic compatible inputs. A MICROWIRE compatible serial data interface is built in to provide extensive diagnostic information. This information includes switch status readback, output load fault conditions and thermal and over-voltage shutdown status.


  • True instantaneous power limit for each switch
  • High survival voltage (60VDC, 80V transient)
  • Shorted load (to ground and supply) protection
  • LS TTL/CMOS compatible logic inputs and outputs
  • Serial data interface for 11 diagnostic checks
  • Over-voltage shutdown at VCC>35V
  • 1.3R Maximum on resistance over-temperature
  • <10µA Supply current in sleep mode
  • -5V Output clamp for discharging inductive loads
