A3992
DMOS Dual Full-Bridge
Microstepping PWM Motor Driver
Serial Interface Description
The A3992 is controlled via a 3 wire serial port. The
programmable functions allow maximum ? exibility in
con ? guring the PWM to the motor drive requirements.
The serial data is written as two 19 bit words, 1 bit
to select which word (referred to here as Word 0 and
Word 1 ) and 18 bits of data. The serial port is de ? ned
D7 – 12 Bridge 2 Linear DAC. 6 bit word to set the
desired current level for bridge 2. Setting all bits to
zero disables Full Bridge 2, all drivers off. (See Cur-
rent Regulation in the Functional Description section.)
D13 Bridge 1 Phase. This bit controls the direction
of current for motor phase 1 as de ? ned below:
in the following tables and text descriptions.
