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.

OUT

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.

PHASE

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.
