Compact Intelligent Power Modules

Compact IPMs from onsemi are fully-integrated inverter power stages consisting of a high-voltage driver, six IGBT’s and a thermistor, suitable for driving permanent magnet synchronous (PMSM) motors, brushless-DC (BLDC) motors, and AC asynchronous motors. The IGBTs are configured in a 3-phase bridge with separate emitter connections for the lower legs offering maximum flexibility in the choice of control algorithm. The power stage has a full range of protection functions including cross-conduction protection, external shutdown and under-voltage lockout functions. An internal comparator and reference connected to the over-current protection circuit allows the designer to set the over-current protection level.

Features:

DBC for lowest thermal resistance and highest power density
Smaller and cooler module for rated power level simplifies thermal design and reduces system cost
IGBT/diode optimized for best power efficiency while meeting EMI requirements
Over-current Protection Circuit
Under-voltage lockout for all channels
Cross-conduction prevention circuit
Thermistor for case temperature monitoring
