Description

3A, 55V DMOS Full-Bridge Motor Drive

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.

Features
* DMOS power stage rated at 55V and 3A continuous
* Low R_DS(ON) of typically 0.3ohm per power switch
* Internal clamp diodes
* Low-loss current sensing method
* Digital or analog control of motor current
* TTL and CMOS compatible inputs
* Thermal shutdown (outputs off) at TJ = 155C
* Overcurrent protection
* No shoot-through currents
* 15-lead TO-220 molded power package

Application
* Full, half and microstep stepper motor drives
* Stepper motor and brushed DC motor servo drives
* Automated factory, medical and office equipment
