48V motor driver IC enables more compact powertrain designs
Texas Instruments simplifies the drive design for mild hybrid vehicles with new driver chip.

The motor driver complies with AEC-Q100 Grade 0 and also protects 48 V powertrain systems from switching-related voltage spikes up to 95 V as well as load shedding, over a wide temperature range from -40 °C to +150 °C. Separate protection circuits can therefore be omitted. Separate protective circuits can therefore be omitted.

In terms of functional safety, the DRV3255-Q1 was developed using TI's certified Functional Safety hardware development process. In addition, there are built-in safety mechanisms and documentation such as a Failure Mode, Effects and Diagnostics Analysis and a Functional Safety Manual. In addition to the safety mechanisms for the device's internal failure modes, the digital input and output pins can handle voltages up to an absolute maximum of 75 V, so the DRV3255-Q1 is protected against overvoltages on the external 12 V supply.
