MC33486A

Rev 2.0, 12/2005

Dual High-Side Switch for

H-Bridge Applications

This 33486A is a self-protected dual 15 m鈩?high-side switch that

incorporates a dual low-side switch control and protection features.

This device is used to replace electromechanical relays and discrete

devices in power management applications. It is designed for typical

DC-motor control in an H-Bridge configuration.

The 33486A can directly interface with a microcontroller for control

and diagnostic functions. It is PWM-capable and has a self-adjusting

switching speed for minimizing electromagnetic emission.
