IRMCT3UF1
Overview
The IRMCT3UF1 is a complete Sensorless drive system based on a proprietary digital motion control ASIC.
The system is based on a configurable control engine implemented by hardware logics in the ASIC. The
system has a simple and low cost structure, made possible by an advanced IR motion power components
including the MOSFET module and IR2011 monolithic gate driver IC. These components together with the
ASIC simplify hardware implementation. Since all control logic is implemented in hardware state machine
as opposed to programmed software, unmatched parallel computation is achieved resulting in higher
bandwidth control and higher motor operating frequency (< 25µsec PWM period).

Pin Descriptions
MOT_RTN (Pins 1, 2) - These two pins are connected
to the motor bus voltage return path as well as the
control power supply grounds.
CS_LU, CS_LV, CS_LW (Pins 19, 20 & 21) -
Control side inputs from the current sense
resistors. These monitor the voltage waveform at
the top of the current sense resistor and use this
signal to track the rotation of the motor. An
approximate value for the resistor can be found
using the Servo Designer software needed to
configure the motor controller. The pins must be
connected directly to the corresponding pins on the
power side and care should be taken to make sure
all three traces are approximately equal in length.
Use low-inductance shunt resistors and keep leads
short.
CS_LW, CS_LU and CS_LV (Pins 3 & 4, 8 & 9,
12 & 13) - These pins are the current sense
connections for corresponding motor phase. The
pins on the power side are the output of the low
side MOSFETs and must be connected to the
current sense resistor in the external application.
Each pin must also be connected to the
coresponding current sense connection on the
control side (see CS_LU, CS_LV, CS_LW
description below).
GND (Pins 22, 23 & 25) - Ground connections
for the +15V, +5V and +3.3V power supplies. All
three should be connected. This can be
accomplished at the hybrid interface or by tying all
three pins to a common ground plane.
PHASE_W, PHASE_U, PHASE_V (Pins 5 & 6,
10 & 11, 14 &15) - Motor connections for the three
phases.
VBUS (Pins 16 & 17) - Input voltage for the motor.
The nominal value is 28Vdc with a maximum of 48V.
+15V, +5.0V, +3.3V (Pins 7, 24 & 26) - Local
housekeeping power supplies for the unit. The
+15V power supply is used to drive the MOSFETs and
should be rated at 100mA. The +5.0V and +3.3V
supplies are responsible for the rest of the ICs in
2.5V_REF_BUF (Pin 18) - 2.5V reference buffer
provided for speed command referencing.
(see SPD_CMD description)

IRMCT3UF1
the circuit including logic and the iMotion digital
controller. The +5.0V supply should be rated at
100mA and +3.3V supply at 200mA.
FLT_CLR, FAULT (Pins 32 & 33) - Fault indication
and Fault Clear function. Use these pins to monitor
the Fault status of the controller. When there is no
fault (clear condition), the fault pin is low. It goes to
3.3V upon the occurrence of a Fault. The controller
can be reset by pulsing the Fault Clear pin high for
a minimum of 1µs. This is a Schmitt input and is
5.5V tolerant.
RX, TX (Pins 27 & 28) - RS-232 interface pins for
programming the controller. The interface operates
at 57.6kBaud.
SPD_CMD (Pin 29) - Speed command for the
motor controller. For the IRMCT3UF1, there are two
operating ranges for the speed command input: 0-
2.5V and 2.5-5V. In each case, 2.5V is zero speed
and the other extreme (0V or 5V) is maximum
speed. An external 2.5V reference is provided to
help configure a particular speed command
interface.
START/STOP (Pin 34) - Start and Stop command for
the controller. The drive will start on the rising edge
of the command and will stop on the falling edge.
This is a Schmitt input and is 5.5V tolerant.
GRN, RED (Pins 30 & 31) - Outputs for driving
Green and Red LEDs. These outputs are provided
as a visual interface to determine the status of the
drive. The Green LED output indicates a clear
condition and the Red LED indicates that a Fault
has occurred. Each output is referenced to +3.3V
and is capable of driving a maximum current of
30mA. Also, each output has an internal series
resistance of 100Ω.
