3A, 55V H-Bridge - LMD18200

LMD18200 (ACTIVE)

3A, 55V H-Bridge

Recommended alternative parts

  • LMD18201  -  LMD18200 Without Current Sensing Circuitry
  • LMD18245  -  Has Current Sensing Circuitry And Digital (4 Bit DAC) Control Of Motor Current

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.

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
