MC33186DH1 HSOP20

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 (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 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 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
