Can be designed without a heatsink
Optimized for PCB layout simplification

STMicroelectronics has added five new space-saving surface-mount intelligent power modules (IPMs) to its SLLIMM™-nano family.

This new module provides particularly high conduction and switching efficiency in hard-switching circuits at frequencies up to 20 kHz. The integrated gate-driver circuit is designed to minimize electromagnetic emission (EMI) by managing the switching voltage and current slope (dV/dt, di/dt).

In addition, it is provided in a highly thermally efficient package to improve reliability, allows for design without a heatsink, and enables safe insulation on a small dual-inline SMD footprint thanks to a creepage of 2.7 mm and a clearance of 2.0 mm. The pin configuration of this module is optimized to simplify the PCB layout.

Various household and industrial devices, such as small fans and roller shutters, refrigerator compressors, dishwashers, drain and recirculation pumps, and general low-power motor drives, will benefit from the low-noise performance of this new IPM product, as well as its compact size, high energy efficiency, and excellent reliability and safety.

Additional features integrated with a gate driver and a 500V MOSFET or 600V IGBT/freewheel-diode array include independent operational amplifiers and comparators that allow the designer to implement advanced current sensing and overcurrent protection with minimal external components.

In addition, it has built-in smart shutdown functions including high-speed fault detection, interlocking, and UVLO (Under-Voltage Lockout), and an integrated bootstrap diode can simplify power supply to the module's gate-control circuit.
