MOTIX™ TLE9189x Next-Generation 3-Phase Gate Driver

Infineon Technologies MOTIX TLE9189x reliable, scalable, and cost-optimized gate driver ICs for 12 V brushless DC motors offer advanced safety features

Image of Infineon Technologies MOTIX™ TLE9189x Next-Generation 3-Phase Gate DriverThe Infineon Technologies MOTIX TLE9189x gate driver ICs feature a conventional motor control concept via PWM input and three integrated current sense amplifiers for accurate current measurement with a precise configurable reference voltage (3.3 V/5 V). The adaptive MOSFET control feature helps improve EMC performance, achieve target switching time, and reduce power losses. The supply voltage range (4.2 V to 36 V) is optimized for automotive 12 V battery systems.
