Automotive vehicles have steadily grown in complexity where the number of power MOSFETs increases continuously as more features are embedded in every new car sold worldwide.

From power liftgates, sunroofs, and seatbelt pre-tensioners to fuel pumps and HVAC blowers, vehicles will often leverage actuators such as DC motors and solenoids to electrically control various subsystems.

In order for these DC motors to operate seamlessly, automotive-grade motor driver ICs are required that can withstand the most demanding environments.

Motor driver ICs interface with processors to supply a regulated current to the motor.

Due to their location near the engine, motor control solutions for automotive pumps and fans must be highly robust.

This is precisely what Infineon’s automotive-grade MOTIX™ BTN99x0LV half-bridge IC is for.

This device provides a cost-optimized solution for protected high-current PWM motor drives with very low board space consumption. 

An H-bridge circuit used to control the DC motor uses four general-purpose I/O of the MCU. However, when the two IS pins are joined into one A/D port, the total I/O used is three. This very simple interface ensures that the BTN99x0LV is easy-to-use, easy-to-integrate, and requires only minimal software effort. 

Infineon’s motor driver ICs go beyond an AEC-101 qualification with dedicated automotive design goals and enhanced testing based on 40 years of legacy in the automotive industry.
