PRELIMINARY INFORMATION

DUAL FULL-BRIDGE  
PWM MOTOR DRIVER  
The A2927SEB motor driver is designed to drive both windings of a  
bipolar stepper motor or bidirectionally control two dc motors. Both  
bridges are capable of sustaining 50 V and include internal pulse-width  
modulation (PWM) control of the output current to 1.5 A.

For PWM current control, the maximum output current is determined  
by the user’s selection of a reference voltage and sensing resistor. Two  
logic-level inputs select output current limits of 0, 33%, 67%, or 100%  
of the maximum level. A PHASE input to each bridge determines load  
current direction. Active-low ENABLE inputs control the four drivers in  
each bridge.

Internally generated delays prevent cross-over currents when  
switching current direction. Special power-up sequencing is not required.  
Thermal protection circuitry disables the outputs if the chip temperature  
exceeds safe operating limits.

The A2927SEB is supplied in a 44-lead power PLCC for surface-  
mount applications. Its batwing construction provides for maximum  
package power dissipation in the smallest possible construction.
