LMD18200T

LMD18200T is a kind of 3A H-bridge. It uses a a multi-technology process which combines bipolar and CMOS control circuitry with DMOS power devices on the same monolithic structure. The typical applications include DC and stepper motor drives, position and velocity servomechanisms, factory automation robots, numerically controlled machinery and computer printers and plotters.

The following is the features of LMD18200T. First, it delivers up to 3A continuous output. Secondly, it operates at supply voltages up to 55 V. Then is low RDS(ON) which is typically 0.3 per switch. Next is TTL and CMOS compatible inputs. The fifth is no "shoot-through" current. The sixth is thermal warning flag output at 145. The seventh is thermal shutdown (outputs off) at 170. The eighth is internal clamp diodes. The ninth is shorted load protection. At last,it has internal charge pump with external bootstrap capability.

What comes next is absolute maximum ratings of LMD18200T. The total supply voltage (VS, Pin 6) is 60 V. The voltage at pins 3, 4, 5, 8 and 9 is 12 V. The voltage at bootstrap (Pins 1 and 11) is VOUT +16 V. The peak output current (200 ms) is 6 A. The Continuous output current is 3 A. The power dissipation is 25 W. The power dissipation (TA=25, free air) is 3 W. The junction temperature, TJ(max) is 150. The ESD susceptibility is 1500 V. The storage temperature, TSTG is from -40 to +150. The lead temperature (soldering, 10 sec.) is 300.
