High Voltage 3-Phase Motor Driver

Features and Benefits

Description

▪ 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

TheSCM1101Minverterpowermodule(IPM)deviceprovides

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

take85to253VACinputvoltage,and10A(continuous)output

current. They can withstand voltages of up to 600 V (IGBT

breakdown voltage).

▪ 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

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.

▪ UL Recognized Component (File No.: E118037)

Package: Power DIP

Applicationsincluderesidentialwhitegoods(homeappliances)

and commercial appliance motor control, such as:

▪ Air conditioner fan motor

▪ Refrigerator compressor motor

▪ Washing machine main motor

▪ Air conditioner compressor motor
