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
R_DS(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 (PWMed) at frequencies up to 10 kHz. This
device is powered by SMARTMOS technology.
The 33186 is parametrically specified over a temperature range of
-40 C  T_A  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
• R_DSON = 150 m for each output transistor at 25 C
• Continuous DC load current 5.0 A (TC < 100 C
• Output current limitation at typ 6.5 A +/- 20%
• Short-circuit shutdown for output currents over 8.0 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 47 F minimum at
VBAT
