Infineon TLE9850QX/TLE9851QXW half-bridge driver IC

Infineon Embedded Power ICs TLE9850QX and TLE9851QXW are highly integrated, AEC Q-100 qualified half-bridge driver motor control solutions for unidirectional applications such as HVAC blowers. The advantages are that the PWM control and the integrated calibrated current sense amplifier allow the motor currents to be adapted. Consequently, the mechanics and the motor can be optimized towards the application requirements. Compact footprint and minimized number of external components allow for reduced PCB size, while at the same time, the noise behavior of the motor improves.
