Features Delivers up to 3A continuous output Operates at supply voltages up to 55V Low RDS(ON) typically 0.33Ω per switch at 3A TTL and CMOS compatible 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 Description The LMD18200 is a 3A H-Bridge designed for motion control applications. The device is built using a multi-technology process which combines bipolar and CMOS control circuitry with DMOS power devices on the same monolithic structure. Ideal for driving DC and stepper motors; the LMD18200 accommodates peak output currents up to 6A. An innovative circuit which facilitates low-loss sensing of the output current has been implemented.
