ENABLE AND RESET FUNCTION AND MO SIGNAL
TA8435H/HQ
Figure 1: 1-2 phase drive mode (M1: H, M2: L)
The ENABLE signal at High level disables only the output signals. Internal logic functions proceed in accordance
with input clock signals and without regard to the ENABLE signal. Therefore output current is initiated by the
timing of the internal logic circuit after release of disable mode. Figure 1 shows the ENABLE functions for when
1-2 phase drive is selected for the system.
Figure 2: 1-2 phase drive mode (M1: H, M2: L)
The RESET signal at Low level not only turns off the output signals but also stops the internal clock functions,
while MO (Monitor Output) signals are set to low. Output signals are initiated from the initial point after release
of RESET (High), as shown in Figure 2. MO signals can be used as rotation and initial signals for stable
rotation checking.
