Tackling the challenge of achieving improved fuel efficiency, reducing CO2 emissions and increasing the reliability of vehicles means looking at every possible source of energy loss and rethinking the way the associated sub-system is built. This is why electric fluid pumps are replacing mechanical systems as they can help reduce losses from hydraulic friction.
Electric fuel pumps are most often implemented with brushless DC (BLDC) motors and ST has a complete range of three-phase gate drivers and Power MOSFETs to power them. SPC5 32-bit automotive-grade microcontrollers plus dedicated voltage regulators and power management ICs simplify the design of high-efficiency solutions.

Based on the EVAL-L99ASC03 evaluation board designed for sensorless 3-phase BLDC motor control, the system features enhanced power management power supply functions including various standby modes. The motherboard, based on an STM8 microcontroller, provides the logic section for monitoring and driving the L99ASC03G 3-phase motor pre-driver assembled in the daughterboard.
ST also provides dedicated user-friendly software with a Graphic User Interface (GUI) that enables the user to set L99ASC03G parameters while displaying device information in real time.
Developers can easily evaluate their brushless DC motor control solution for a variety of circulation and booster pump applications for coolant, water, fuel or oil lines.
