B¯, B_SEL, and SYNC pins
These inputs operate with CMOS input. The default state is high
impedance, and they must be driven to logic high or logic low.
When these logic input pins are used, they should be pulled down
to the ground side using a 1 to 10 kΩ resistor. Any of these pins
that are not used must either be pulled up to the VDD side or be
pulled down to the ground side.
If they are left open, malfunction or permanent damage to the
product may result. For example, in case the signal from the
microcomputer has high impedance, a pull-down or pull-up resis-
tor should be provided. In particular, when an INx pin is in high
impedance during operation, abnormal oscillation of the output
may be caused and in the worst case, this will result in permanent
damage to the MOSFETs.
A low pass filter (LPF) is provided on each the logic input pin.
These improve noise filtering.
Sleep Mode
The SLA7080M can be set into Sleep mode, in which the motor
is not controlled, so it can move freely. To enable Sleep mode, set
the REF pin at more than 2 V. In Sleep mode, the device stops the
main power supply and decreases circuit current.
When shifting the device directly from the Sleep mode to the
normal operating mode (motor rotation), not only the rise time
of the device, but also the rise time of motor excitation current
should be considered when determining the amount of time lag
from the cancellation of Sleep mode to the next motor phase
input command. As shown in figure 8, a minimum lag of 100 μs
is recommended.
Because of the built-in circuit protection features, be cautious
about taking too long when switching between the Motor Cur-
rent Setting range and the Sleep Limit range (refer to figure 9).
Because the VOCP level occurs in the Prohibited range, between
those two areas, if the switching time is too lengthy, overcurrent
protection will start operating when VSENSE > VOCP.
FLAG pin
This is the output for the protection circuit:
FLAG Pin Output Logic
Low
Normal operation
High
Protection circuit operation
It is designed for CMOS output, as shown in the equivalent
circuit in figure 10. Therefore, if the FLAG logic pin is not used,
it must be left open.
Internal Sense Resistors, RS
Sense resistors which detect motor currents are incorporated in
this product series. The values of the internal sense resistors, RS ,
can be calculated (for the standard SLA7080M variants listed in
this document) by applying the power loss formula:
P
≈ IO2 × RS .
