SCM1101M
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
Integrated Fast Recovery Diode (FRD) as freewheeling
diode for each IGBT
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
UL Recognized Component (File No.: E118037)
Package: Power DIP
Description
The SCM1101M 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 10A(continuous) output
current. They can withstand voltages of up to 600 V (IGBT
breakdown voltage).
The SCM1100M series employs a new, small-footprint
proprietary DIP package. The IC itself consists of all of the
necessary power elements (six IGBTs), pre-drive ICs (three),
and freewheeling 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

NOTE:
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) – 0.0024 (Ω).
To avoid malfunction, the wiring between the LS and COM pins should be as short as possible.
To prevent surge destruction, put a 0.01 to 1 μF snubber capacitor, CS, in parallel with the electrolytic capacitor.
To prevent surge destruction, put a 18 to 20 V Zener diode between the VCC and COM pins.
To prevent surge malfunction, put a 0.01 to 0.1 μF ceramic capacitor between the VCC and COM pins and the VB and HS
pins.
