STOLLMOSGENERICTOBO1

STOLLMOSGENERICTOBO1 is a Generic Power Board for 12V applications suitable for automotive inverter applications to control fans or pumps driven by BLDC motors. The system is controlled by system on-chip MOTIX™ MCU, which features integrated MOSFET drivers in combination with OptiMOS™-7 40V leadless MOSFETs. The board is equipped with 6 MOSFETs equipped in PGHSOF-5 package (sTOLL), one MCU with LIN and integrated 3-phase BLDC MOSFET gate driver. The board allows for the configuration of the common low-side shunt-resistor of the B6-bridge using three resistors connected in parallel. All active components, including the seven MOSFETs and the driver IC, are arranged over a large area on the board to distribute heat evenly across the PCB. The shunt resistors, serving as passive components, also act as additional heat sources, collecting all return current from the three legs of the bridge. The board is designed to dissipate heat from the shunt resistors effectively through thermal pads.
