LMD18245  
3A, 55V DMOS Full-Bridge Motor Driver  
General Description  
Features  
n DMOS power stage rated at 55V and 3A continuous  
n Low RDS(ON) of typically 0.3per power switch  
n Internal clamp diodes  
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 struc-  
ture. The LMD18245 controls the motor current via a fixed  
off-time chopper technique.  
n Low-loss current sensing method  
n Digital or analog control of motor current  
n TTL and CMOS compatible inputs  
n Thermal shutdown (outputs off) at TJ 155˚C  
n Overcurrent protection  
=
An all DMOS H-bridge power stage delivers continuous out-  
put currents up to 3A (6A peak) at supply voltages up to 55V.  
The DMOS power switches feature low RDS(ON) for high ef-  
ficiency, and a diode intrinsic to the DMOS body structure  
n No shoot-through currents  
n 15-lead TO-220 molded power package  
eliminates the discrete diodes typically required to clamp bi- Applications  
polar power stages.  
n Full, half and microstep stepper motor drives  
An innovative current sensing method eliminates the power  
loss associated with a sense resistor in series with the motor.  
A four-bit digital-to-analog converter (DAC) provides a digital  
path for controlling the motor current, and, by extension, sim-  
plifies implementation of full, half and microstep stepper mo-  
tor drives. For higher resolution applications, an external  
DAC can be used.  
n Stepper motor and brushed DC motor servo drives  
n Automated factory, medical and office equipment
