DMOS DUAL FULL-BRIDGE  
PWM MOTOR DRIVER  
Designed for pulse-width modulated (PWM) current control  
of two dc motors, the A3974SED is capable of output currents to  
±1.5 A and operating voltages to 50 V. Internal fixed off-time  
PWM current-control timing circuitry can be programmed via a  
serial interface to operate in slow, fast, and mixed current-decay  
modes.

Synchronous rectification circuitry allows the load current to  
flow through the low rDS(on) of the DMOS output driver during  
the current decay. This feature will eliminate the need for  
external clamp diodes in most applications, saving cost and  
external component count, while minimizing power dissipation.

Internal circuit protection includes thermal shutdown with  
hysteresis, undervoltage monitoring of VDD and the charge  
pump, and crossover-current protection. Special power-up  
sequencing is not required.

ABSOLUTE MAXIMUM RATINGS  
The A3974SED is supplied in a 44-lead plastic PLCC with  
four copper batwing tabs for maximum heat dissipation. The  
power tabs are at ground potential and need no electrical isola-  
tion.
