SL-MCIMC01002V1

Solution Description

The Automotive market is increasingly demanding higher fuel efficiency, reduced CO2 emissions and improved reliability. The use of electric pumps, integrating or substituting mechanical ones, helps address these needs thanks to reduced friction hydraulic losses and power on-demand

A leading automotive supplier, ST offers a solution for 12V electric BLDC motors for water, coolant, oil and fuel pumps

Key Product Benefits

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
