1-2-6 High Voltage 3-Phase Brushless Motor Driver ICs
SCM1200M Series IGBT Output Element, Built-in Thermal Shutdown, Overcurrent Protection, and Shoot Through Prevention Circuits
■Features
• Six IGBTs and six FRDs for the 3-phase bridge, a pre-drive IC, and a boot diode are integrated into a single package
• Ideal for driving air conditioner compressors, washing machine drums, and refrigerator compressors
• Built-in shoot through prevention (STP) circuit (when the ON signal is input simultaneously)
• All IGBTs can be shut down when commonly connected to the FO pin.
• Three built-in bootstrap diodes
• Supports CMOS (3.3 and 5 V) input levels
• Built-in undervoltage lock out (UVLO) circuit (auto regression)
• Built-in overcurrent protection (OCP) circuit
• Built-in thermal shut down (TSD) circuit (auto regression)
• Fail signal output during operation of the UVLO (low side only), OCP, or STP circuit
