2927 DUAL FULL-BRIDGE PWM MOTOR DRIVER PRELIMINARY INFORMATION (Subject to change without notice) September 16, 1997 2927 DUAL FULL-BRIDGE PWM MOTOR DRIVER The A2927SEB motor driver is designed to drive both windings of a bipolar stepper motor or bidirectionally control two dc motors. Both bridges are capable of sustaining 50 V and include internal pulse-width modulation (PWM) control of the output current to 1.5 A. 39 GND Data Sheet 29319.23 SENSE 1 PHASE 1 VREF 1 ENABLE 1 43 42 41 RC1 E 44 GND EN1 VCC θ1 40 6 5 4 3 2 1 LOGIC SUPPLY OUT 1A OUT 1B I10 I11 1 7 8 9 10 11 12 13 14 15 16 17 VBB PWM 1 38 37 1 36 35 34 33 For PWM current control, the maximum output current is determined by the user’s selection of a reference voltage and sensing resistor.
