Document Number: MC33186  
Rev. 7.0, 10/2011  
Freescale Semiconductor  
Technical Data  
H-Bridge Driver  
The 33186 is a monolithic H-Bridge ideal for fractional horsepower  
DC-motor and bi-directional thrust solenoid control. The IC  
33186  
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.  
H-BRIDGE MOTOR DRIVER  
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.  
Features  
• Overtemperature, Short-Circuit Protection, and Overvoltage  
Protection against Transients up to 40 V at VBAT Typical  
• RDSon = 150 mΩ for each output Transistor at 25°C  
• Continuous DC Load Current 5 A (TC < 100°C)  
• Output Current Limitation at typ 6,5 A +/- 20%  
• Short-Circuit Shutdown for Output Currents over 8 A  
• Logic Inputs TTL/CMOS Compatible  
• Operating Frequency up to 20 kHz  
• Undervoltage Disable Function  
• Diagnostic Output, 2 Disable Input
