iMOTION™ Integrated Power Module (IPM) Fully integrated power modules for BLDC motor control
Motor controller IC and a three-phase inverter stage in a single package
IPM is a family of fully integrated modules for the control of three-phase motors, optimized for low-power devices. Within the iMOTION™ IPM family, there are two different series: The IMM100 and IMI110, which combine the motor controller IC and a three-phase inverter stage in a single package, minimizing external components count and PCB area. The three-phase inverter stage is based either on six MOSFETs or six IGBTs. These iMOTION™ IPMs offer the highest integration level by making use of the field-proven iMOTION™.
Motion Control Engine (MCE) in combination with providing all required hardware functions: From single shunt current sensing to bootstrap capability, signal filtering and several hardware protections like dead-time insertion and shoot through prevention. An iMOTION™ PM does not require a heatsink and addresses motor drives with a typical application input power between 70 W and 80W with 600 V maximum DC blocking voltage, depending on the chosen product variant.
All IMI110 and IMM100 devices support the functional safety requirements according to the IEC/UL 60730 ("class B").
The block diagram illustrates the various options that the IPM family has to offer. The table of IMM100 and IMI110 Series, which combine the motor controller IC and a three-phase inverter stage in a single package, minimizing external components count and PCB area. The three-phase inverter stage is based either on six MOSFETs or on six IGBTs.
