LMD18200 3Amp. Motor Driver Ic

Introduction

The LMD18200 is a 3A H-Bridge designed for motion control applications. This is one of the best motor driver we have encountered. While driving 3 Amps of load it gets barely warm and it is very difficult to blow. LMD18200 can handle peak output currents up to 6A. It also gives current sense output without need of high power shunt resistor making it very easy to use.

Specifications

• Delivers up to 3A continuous output
• Operates at supply voltages up to 55V
• Low RDS(ON) typically 0.3Ù 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

Applications

• DC and stepper motor drives
• Position and velocity servomechanisms
• Factory automation robots
• Numerically controlled machinery
