JAJSET8B June 2014 – February 2018 DLPA2000
PRODUCTION DATA.
Two control modes are available in the DLPA2000: IN/IN mode and PHASE/ENABLE mode. IN/IN mode is selected if the MODE pin is driven low or left unconnected; PHASE/ENABLE mode is selected if the MODE pin is driven to logic high. Table 2 and Table 3 show the logic for these modes.
The main difference between both modes is that to change the rotation direction for IN/IN mode, both xIN1 and xIN2 signals must change polarity, while for PHASE/ENABLE mode, the PHASE signal must be held high while the PHASE signal is used to change rotation direction for a DC motor. In case a stepper motor is used, the sequence of OUT1 and OUT2 determines the rotation direction.
The motor position is changed by using the internal, register-generated, control signals AIN1 and AIN2 (register 0F[123:122] in combination with BIN1 and BIN2 (register 0F[121:120].
