Description
The TLE7184F is a system IC for Brushless Motor Control. It incorporates a voltage supply for a µC, a bridge driver
for a B6 configuration, an application typical PWM interface and some other smaller features. Target is to reduce
the number of discrete components in typical BLDC automotive applications and give enough flexibility for custom
specific adaptations.
It works with 3-phase motors and brush DC motors. Its exposed pad package allows the usage even at high
ambient temperatures.
