The MC33143 is a dual high–side switch designed for solenoid control in

harsh automotive applications, but is well suited for other environments. The

device can also be used to control small motors and relays as well as

solenoids. The MC33143 incorporates SMARTMOS technology, with

CMOS logic, bipolar/MOS analog circuitry, and DMOS power outputs. An

internal charge pump is incorporated for efficient gate enhancement of the

internal high–side power output devices. The outputs are designed to

provide current to low impedance solenoids. The MC33143 provides

individual output fault status reporting along with internal Overcurrent and

Over Temperature protection. The device also has Overvoltage protection,

with automatic recovery, which “globally” disables both outputs for the

duration of an Overvoltage condition. Each output has individual Overcurrent

and Over Temperature shutdown with automatic retry recovery. Outputs are

enabled with a CMOS logic high signal applied to an input to providing true

logic control. The outputs, when turned on, provide full supply (battery)

voltage across the solenoid coil.
