To Your Basket Ordering Information Part Number: R27-18200 Price: $13.00 Weight: 0.02 lbs H-bridge with 3A capacity. Operates at supply voltages from 12V to 55V. These bridges are great for bigger motors.

More Details:

• Delivers up to 3A continuous output
• Operates at supply voltages from 12V up to 55V
• Low R_DS(ON) typically 0.3 Ohm 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

This driver is great when the cheaper and smaller Texas Instruments SN754410NE H-Bridge won't work. Each chip is a single H-Bridge driver capable of handling 6A peak (200ns) and 3A continuous current. This is the HBridge used in our 3A Back-EMF HBridge Board.

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. An innovative circuit which facilitates low-loss sensing of the output current has been implemented in this chip.

Application Notes:

• A DMOS 3A, 55V, H-Bridge: The LMD18200 (370 Kbytes)
  
• Increasing the High-Speed Torque of Bipolar Stepper Motors (208 Kbytes)
