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
▪ 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 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 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 DIP package. 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
