MC33186VW2 H-Bridge Motor Driver IC – 5A Continuous Output with 150mΩ RDS(ON) for Throttle Control Actuators

The MC33186VW2 is a monolithic H-Bridge power IC specifically developed for driving fractional horsepower DC motors and bi-directional thrust solenoids in automotive and industrial applications. This device integrates internal control logic, a charge pump, gate drive circuitry, and low RDS(ON) MOSFET output stages into a compact 20-pin HSOP surface-mount package with an exposed thermal pad for efficient heat dissipation.

This driver operates over a wide supply voltage range from 5.0V to 28V, with parametric performance specified across the full -40°C to +125°C temperature range. The device can also withstand transient conditions up to 40V with derated specifications. It is capable of delivering a continuous inductive DC load current of 5.0A (at TC < 100°C), with each output transistor featuring a typical RDS(ON) of just 150mΩ at 25°C, ensuring efficient power delivery and reduced thermal losses.

The MC33186VW2 includes comprehensive protection features essential for automotive reliability. Output current limitation activates at a typical 6.5A (±20%), while short-circuit shutdown triggers for output currents exceeding 8A. Additional safeguards include overtemperature protection with hysteresis, undervoltage disable function, and overvoltage protection against transients up to 40V. A diagnostic Status Flag output provides fault feedback to the system ECU, while two disable inputs enable flexible fail-safe control.

Logic inputs are TTL/CMOS-compatible, and the device supports PWM frequencies up to 10kHz for precise motor speed and torque regulation. The IC is available in a Pb-free 20-HSOP package designated by the VW suffix code. This driver is the ideal choice for electronic throttle control (ETC), exhaust gas recirculation (EGR) valves, and other DC motor actuator applications in modern engine management systems.
