FACT SHEET
MC33887 POWER H-BRIDGE DRIVER WITH SLEEPMODE
The MC33887 is a monolithic power IC comprising control logic, charge pump, gate drive,
and low RDS(on) MOSFET output H-Bridge circuitry into a small surface mount package. It is
designed to drive inductive loads with RMS currents up to 5.2 A in both directions. In addi-
tion, the current drive can be pulse width modulated (PWM) at frequencies up to 20 kHz. An
internal current mirror circuit provides a proportional (1/400th) sample of the output current,
which may be used to provide feedback or load information to a microcontroller’s A/D input.
APPLICATIONS
• Automotive Systems
• DC-Motor Control in
Industrial and Robotic
Systems
Under voltage, over tempera-
ture, and over current condi-
tions are detected and reported
• DC-Motor and
Actuator Control in
Boats, RV’s and
Marine Systems
Simplified Application Diagram
via a status flag output. Output
V
control is via two independent
inputs (each half of the bridge
may be utilized as an inde-
pendent totem pole output).
Enables can place the bridge
into sleep mode (<25 µA).

QUESTIONS
• Do you need to control a DC-motor via microprocessor?
• Are you designing a DC-motor controller for motors up to 5.2 A and up to 28 V DC?
• Do you need to drive a motor in both forward and reverse or a solenoid in both push and
pull?
• Do you need to incorporate PWM speed and torque control?
• Do you need to provide active braking and freewheeling?
