LMD18201
Description
The LMD18201 is a 3A H-Bridge designed for motion control applications. The device is built using a multi-technology process which bines bipolar and CMOS control circuitry with DMOS power devices on the same monolithic structure. The H-Bridge configuration is ideal for driving DC and stepper motors. The LMD18201 acmodates peak output currents up to 6A. Current sensing can be achieved via a small sense resistor connected in series with the power ground lead. For current sensing without disturbing the path of current to the load, the LMD18200 is remended. n n n n n n n TTL and CMOS patible inputs No “shoot-through” current Thermal warning flag output at 145˚C Thermal shutdown (outputs off) at 170˚C Internal clamp diodes Shorted load protection Internal charge pump with external bootstrap capability
