Analog Products Fact Sheet Power Actuation MC33186 H-Bridge Motor Drivers 5.0 A H-Bridge DESCRIPTION 33186 SIMPLIFIED APPLICATION DIAGRAM The 33186 is a monolithic H-Bridge ideal for fractional horsepower DC-motor and bidirectional thrust solenoid control. The IC incorporates internal control logic, charge pump, gate drive, and low RDS(ON) MOSFET output circuitry. The 33186 is able to control continuous inductive DC load currents up to 5.0 A. Output loads can be pulse width modulated (PWM-ed) at frequencies up to 10 kHz. CP MCU or DSP APPLICATIONS PERFORMANCE • Automotive Systems Outputs • DC-Motor Control in Industrial and Robotic Systems RMS Current • DC-Motor and Actuator Control in Boats, RVs, and Marine Systems Operating Voltage • Appliance and White Goods Electrical Actuators • Powered Machine and Hand Tools • Antenna Rotors and Dish Positioning Systems VBAT OUT1 SF The 33186 is parametrically specified over a temperature range of -40°C ≤ TA ≤ 125°C, 5.0 V ≤ V+ ≤ 28 V. The IC can also be operated up to 40 V with de-rating of the specifications. The IC is available in a surface mount power package with exposed pad for heat sinking.
