SCM1105MF
High Voltage 3 Phase Motor Driver
Features and Benefits
Each half-bridge circuit consists of a pre-driver circuit that
is completely independent from the others
Protection against simultaneous high- and low-side turning on
Bootstrap diodes with series resistors for suppressing
inrush current are incorporated
CMOS compatible input (3.3 to 5 V)
Designed to minimize simultaneous current through both
high- and low-side IGBTs by optimizing gate drive resistors
UVLO protection with auto restart
Overcurrent protection with off-time period adjustable by
an external capacitor
Fault (FO indicator) signal output at protection activation:
UVLO (low side only), OCP, and STP
Proprietary power DIP package
Package: Power DIP
Description
The SCM1105MF inverter power module (IPM) device
provides a robust, highly-integrated solution for optimally
controlling 3-phase motor power inverter systems and variable
speed control systems used in energy-conserving designs to
drive motors of residential and commercial appliances. These
ICs take 85 to 253 VAC input voltage, and 10 A (continuous)
output current. They can withstand voltages of up to 600 V
(IGBT breakdown voltage).
The SCM1100M series employs a new, small-footprint
proprietary DIPpackage with exposed thermal pad for enhanced
power dissipation capacity. The IC itself consists of all of the
necessary power elements (six IGBTs), pre-drive ICs (three),
and flyback diodes (six), needed to configure the main circuit of
an inverter, as well as a bootstrap circuit (three bootstrap diodes
and three boot resistors) as a high-side drive power supply. This
enables the main circuit of the inverter to be configured with
fewer external components than traditional designs.
Applications include residential white goods (home appliances)
and commercial appliance motor control, such as:
Air conditioner fan motor
Refrigerator compressor motor
Washing machine main motor
Air conditioner compressor motor
Not to scale. Thermal pad shown attached.

NOTE:
All of the input pins are connected to GND with internal pull-down resistors rated at 100 kΩ, however, an external pull-down
resistor may be required to secure stable condition of the inputs if high impedance conditions are applied to them.
To use the OCP circuit, an external shunt resistor, RS, is needed. The RS value can be obtained from the formula:
RS(Ω) = 0.5 V / Overcurrent Detection Set Current (A) .
A blanking timer is built-in to mask the noise generated on RS at turn-on.
The external electrolytic capacitors should be placed as close to the IC as possible, in order to avoid malfunctions from
external noise interference. Put a ceramic capacitor in parallel with the electrolytic capacitor if further reduction of noise
susceptibility is necessary.
