Next-Gen Intelligent Power Modules for Motor Drives from STMicro

STMicroelectronics has extended its SLLIMM nano series of Intelligent Power Modules( IPMs) for motor drives with more package options that help minimize overall size and complexity, extra integrated features, and greater efficiency leveraging the latest-generation 500V MOSFETs. over-current protection and current sensing. Additional built-in safety features include interlocking to prevent shoot-through currents from damaging MOSFETs of the bridge, a fault-status output, shutdown input, and smart- shutdown capability. An optional built-in thermistor helps simplify over-temperature protection.
With a current rating of 1A or 2A, the new IPMs target applications up to 100 Watts, such as refrigerator compressors, washing-machine or dishwasher motors, draining and recirculation pumps, fans, and other drives running at less than 20kHz in hard-switching circuitries. Operation up to 150 ° C allows use in harsh environments.
The modules integrate a three-phase MOSFET bridge and gate-driver HVICs, with value-added features including an unassigned op-amp and comparator for functions such as
