Features • Delivers up to 3A continuous output • Operates at supply voltages up to 55V • Low RDS(ON) typically 0.33 per switch • 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 LMD18201 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. The H-Bridge configuration is ideal for driving DC and stepper motors. The LMD18201 accommodates 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 recommended. Applications • DC and stepper motor drives • Position and velocity servomechanisms • Factory automation robots • Numerically controlled machinery • Computer printers and plotters

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
