Startup operation
When the motor is stationary, there is no back-EMF and the motor position is unknown. On
receiving an analog voltage command input, the rotor is aligned to a known position in DC
excitation mode for a period (tdc), during which the Dci pin voltage decreases to half VDD level.
The time constant for the period is determined by C1 and R1. After that, switching
occurs to forced commutation mode represented by (tf). The duty cycles for DC excitation and
forced commutation modes are determined according to the ramp pin voltage. The ramp duration
is determined by C2.
An external capacitor, in parallel with C1, sets the times that the controller stays in DC excitation
and forced commutation modes. Those times vary depending on the motor type and motor loading.
Thus, they must be adjusted experimentally.
When the number of turn of a motor is more than forced commutation frequency, the motor
switches to sensorless mode. The PWM duty cycle for sensorless mode after the ramp-up time is
determined by the Vin value.

Two Quadrant Mode Of Operation Of BDC Motor
Fig. 9 illustrates the four possible quadrants of operation for a BDC motor. Two-quadrant mode refers
to a motor operating in quadrants I and III. With a two-quadrant BDC motor, friction is the only force to
decelerate the load.
Two-quadrant mode, modulates only the high-side devices of the output power stage, as shown in
Fig. 4. The current paths within the output stage during the PWM on and off times are illustrated in
Fig. 10. During the on time, both switches S1 and S4 are on, the current flows through both switches
and the motor winding. During the PWM cycle off time, the upper switch S1 is shut off, and the motor
current circulates through the lower switch S4 and D2. The motor is assumed to be operated in
quadrants I or III. During direction reversal in quadrants II and IV, the motor current path is as shown
in Fig. 11.
Two-quadrant mode of operation is the most efficient mode, because the controller and motor
switching losses are minimized. Also, EMI emission is minimum with two-quadrant mode of operation.
The limitation of two-quadrant mode of operation is, it is not safe to reverse motor direction at high
speed.
In four-quadrant mode, both upper and lower switches are modulated. Motor current always decays
during off time, eliminating any uncontrolled circulating current. In addition, the current always flows
through the current sense resistor. For servo system applications, refer to SMCT6MXX-XX, or
SMCT6GXX-XX motor controllers.

Current limiting is provided internally by an over-current comparator.
A current monitoring output is provided at Pin 25.
A user adjustable over-current limit reference input is provided at Pin 23.
The over-current reference adjustment procedure is described in the Pin Description section.
Closed Loop Speed Control
The motor speed is directly proportional to the input analog command at Pin 9. However, speed
regulation is poor in open loop systems. For tight speed regulation, a closed loop speed control can
be implemented as shown in Fig. 12.
A tachometer can be used to provide speed feedback information, and an error amplifier to close the
speed loop.

Motor Terminals Connection
Since the rotor position detection is done through the phases, the phase IDs are irrelevant. Any motor
terminal connection to the controller with the sequence ABC, or BCA, or CAB will results in the same
direction of rotation as long as the controller direction input is not changed. A motor terminal
connection sequence of the opposite as CBA, or BAC, or ACB will result in a reversed rotation.

Over-Lap (Pin 17)= low, it is configured to allow for overlap commutation. In overlap commutation,

DC Bus Filtering
To minimize the circuit parasitic inductance effect on the power stage, the layout of Fig. 15 is
suggested. C1, and C2 are 0.5µF to 1µF ceramic capacitors, connected across the DC bus as
close as possible to the controller. Also, a bulk low ESR capacitor C3 with adequately voltage-
rating shall be used.

Cleaning Process for (SMCS6M40-XX-1):
Suggested precaution following cleaning procedure:
If the parts are to be cleaned in an aqueous based cleaning solution, it is recommended that the parts be baked
immediately after cleaning. This is to remove any moisture that may have permeated into the device during the cleaning
process. For aqueous based solutions, the recommended process is to bake for at least 2 hours at 125oC.
Do not use solvents based cleaners.
Soldering Procedure:
Recommended soldering procedure
Signal pins 1 to 26: 210C for 10 seconds max
Power pins 27 to 43: 260C for 10 seconds max.
