For a BOM freeze, this is the tier that avoids a qualification re-run if the project targets a passenger-vehicle or commercial-vehicle program.
That means no last-time-buy window to manage, no risk of a sudden EOL notice interrupting a multi-year production run. For a sourcing desk qualifying a new automotive platform, this removes the supply-risk variable from the motor-drive line item.
Hardware interface — no comms overhead
The driver uses a hardware interface (PWM and direction pins) rather than a serial bus. That means the MCU does not need SPI or I²C firmware to configure the driver — the motor starts when the PWM signal appears. The trade-off is that the driver's protection thresholds and dead-time are fixed; there is no register to tweak for a different motor inductance. For a fixed-motor design (one pump, one blower), this is a BOM simplification. For a multi-motor platform, the fixed-configuration may be a constraint.
