SSM1002MA

SSM1002MA 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 Description The SSM1002MA 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 25 A (continuous) output current. They can withstand voltages of up to 600 V (IGBT breakdown voltage). The SSM1000M series employs a new proprietary DIP package. The IC itself consists of all of the necessary power elements (six IGBTs), pre-driver ICs (four), and flyback diodes (six), needed to configure the main circuit of an inverter, as well as a shunt resistor. This enables the main circuit of the inverter to be config...
