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 (PWM-ed) at frequencies up to 10 kHz.
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.
