Overview

LMD18245 3A, 55V DMOS Full-Bridge Motor Driver April 1998 LMD18245 3A, 55V DMOS Full-Bridge Motor Driver General Description The LMD18245 full-bridge power amplifier incorporates all the circuit blocks required to drive and control current in a brushed type DC motor or one phase of a bipolar stepper motor.
The multi-technology process used to build the device combines bipolar and CMOS control and protection circuitry with DMOS power switches on the same monolithic structure.
The LMD18245 controls the motor current via a fixed off-time chopper technique.
An all DMOS H-bridge power stage delivers continuous output currents up to 3A (6A peak) at supply voltages up to 55V.
The DMOS power switc...
