Infineon Technologies MOTIX™ TLE9140
Gate driver IC for BLDC motors
MOTIX™ TLE9140EQW is a 3-phase motor gate driver IC targeting diverse applications with supply voltage range between 8 ~ 72 V and equipped with comprehensive protection and diagnosis features. The integrated adaptive MOSFET control feature can help to improve EME and reduce power losses as well as save on external components needed in the application. The small TS-DSO-32 packing enables space and weight reduction on the PCB. TLE9140 is a great companion chip to Infineon’s MOTIX™ TLE987x and TLE989x 32-bit motor control SoC solutions allowing customers to easily scale existing MOTIX™ MCU (SoC) designs to higher voltage requirements. In addition, TLE9140 is also compatible with open market MCUs.
