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

“ Flight time continues to be a top design challenge for recreational quadcopters and professional drones , especially those being used by
a recent IHS Markit study *, almost 50 percent of drones in the market have an estimated battery life of less than
30 minutes , 35 percent can fly between 31 and 60 minutes and the remaining 15 percent and less can fly
more than an hour – all under ideal flying conditions without additional payload .
