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

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

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

• 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
