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
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.
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
• Coding Input for Alternative Functions
• Stable Operation with an External Capacitance of Maximum 47 µF
at VBAT
• Pb-Free Packaging Designated by Suffix Code VW

Notes
3. In case of negative voltage at OUT2 (respectively OUT1) this maximum pull down current at DI2 (respectively COD) Pin can be
exceeded. This happens during recirculation when the current is flowing in the low side. See curve 22.
