LMD18200
Description
The LMD18200 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. Ideal for driving DC and stepper motors; the LMD18200 acmodates peak output currents up to 6A. An innovative circuit which facilitates low-loss sensing of the output current has been implemented. n n n n n n 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
Applications n n n n n DC and stepper motor drives Position and velocity servomechanisms Factory automation robots Numerically controlled machinery puter printers and plotters
Features n n n n Delivers up to 3A continuous output Operates at supply voltages up to 55V Low RDS(ON) typically 0.3Ω per switch TTL and CMOS patible inputs
