A4970  
Dual Full-Bridge PWM Motor Driver  
Features and Benefits  
750 mA continuous output current  
45 V output sustaining voltage  
Internal clamp diodes  
Internal PWM current control  
Low output saturation voltage  
Internal thermal shutdown circuitry  
Pin compatible with UDx2916  
DMOS outputs  
Description  
TheA4970motordriverdrivesbothwindingsofabipolarstepper  
motor or bidirectionally controls two DC motors. Both bridges  
are capable of sustaining 45 V and include internal pulse-width  
modulation (PWM) control of the output current to 750 mA.  
For PWM current control, the maximum output current is  
determined by user selection of a reference voltage and sensing  
resistor. Two logic-level inputs select output current limits of  
0%, 33%, 67%, or100%ofthemaximumlevel.APHASEinput  
to each bridge determines load current direction.  
Intrinsic diodes in the MOSFET output structure protect  
againstinductivetransients.Internallygenerateddelaysprevent  
crossover 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.  
Package: 24-pin batwing wide SOIC  
(package LB)  
Thedeviceissuppliedina24-pinsurface-mountwideSOICwith  
two pairs of batwing leads (LB). The webbed-pin construction  
providesformaximumpackagepowerdissipationinthesmallest  
possible construction. The package is lead (Pb) free, with 100%  
matte tin leadframe plating.
