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.
