DUAL FULL-BRIDGE  
PWM MOTOR DRIVER  
The A2918SWH and A2918SWV motor drivers are designed  
to drive both windings of a bipolar stepper motor or bidirectionally  
control two dc motors. All bridges are capable of sustaining 45 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. A PHASE input to each bridge determines load current  
direction. Active low ENABLE inputs control the four drivers in  
each bridge.

GROUND  
The bridges include both ground clamp and flyback diodes for  
protection against inductive transients. 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 A2918SWH/V are supplied in an 18-lead power-tab package  
with staggered lead forming. The tab is internally insulated from the  
device and requires no external isolation. The A2918SWH/V are  
available for operation from -40°C to +85°C. To order, change the  
suffix from 'S–' to 'E–'. These devices are also available on special  
order for operation to +125°C.
