A3959  
DMOS Full-Bridge PWM Motor Driver  
Features and Benefits  
±3 A, 50 V Output Rating  
Low rDS(on) Outputs (270 m, Typical)  
Description  
Designedforpulsewidthmodulated(PWM)currentcontrolof  
DCmotors, theA3959iscapableofoutputcurrentsto±3Aand  
Mixed, Fast, and Slow Current-Decay Modes  
Synchronous Rectification for Low Power Dissipation  
Internal UVLO and Thermal-Shutdown Circuitry  
Crossover-Current Protection  
operatingvoltagesto50V.Internalfixedoff-timePWMcurrent-  
control timing circuitry can be adjusted via control inputs to  
operate in slow, fast, and mixed current-decay modes.  
PHASE and ENABLE input terminals are provided for use  
in controlling the speed and direction of a DC motor with  
externallyappliedPWM-controlsignals.Internalsynchronous  
rectification control circuitry is provided to reduce power  
dissipation during PWM operation.  
Internal Oscillator for Digital PWM Timing  
Packages:  
Internal circuit protection includes thermal shutdown with  
hysteresis, undervoltage monitoring of supply and charge  
pump, and crossover-current protection. Special power-up  
sequencing is not required.  
Package B, 24-pin DIP  
with exposed tabs  
TheA3959providesachoiceofthreepowerpackages,a24-pin  
DIP with batwing tabs (package suffix ‘B’), a 24-lead SOIC  
with four internally-fused pins (package suffix ‘LB’), and a  
thin (<1.2 mm) 28-pin TSSOP with an exposed thermal pad  
(suffix ‘LP’). In all cases, the power pins and tabs are at ground  
potential and need no electrical isolation. Each package is lead  
(Pb) free, with 100% matte tin leadframes.
