The TLE9140EQWXUMA1 from Infineon Technologies is an Automotive-Qualified MOSFET Gate Driver that has been designed for driving a maximum of 3 half-bridges for brushless DC (BLDC) motors in a 24 V/48 V platform. It requires an input voltage of 8 - 75 V. This motor driver IC provides high voltage capability and robustness up to 100 V, which helps to simplify the PCB design. It has a 16-bit serial peripheral interface and a charge pump concept to support a 100% duty cycle. This motor driver benefits from drain-source monitoring, timeout watchdog, cross-current protection, off-state diagnostic, and adaptive MOSFET control. It can be used together with a general microcontroller to transfer the applications to 24 V/48 V platforms. This motor controller IC can also be used together with MOTIX MCU to transfer the applications to 24 V/48 V platforms with minor software development effort.
This AEC-Q100-qualified IC is equipped with under-voltage shutdown, overvoltage shutdown, and over-temperature protection mechanisms to ensure safe operation. It is available in a surface-mount package that measures 8.65 x 3.9 x 1.15 mm and is ideal for engine cooling fans, water pumps and oil pump applications.
