The S12ZVM-EFP is an out-of-box reference design board engineered for 12 V 3-phase permanent magnet synchronous motor (PMSM) automotive electrical fuel pump (EFP).
Based on the 16-bit S12 MagniV® S12ZVM mixed-signal microcontrollers, the S12ZVM-EFP uses smooth cross-over I-F start-up and initial position detection (IPD) algorithm to ensure the robust and fast start-up for achieving the strict goal of below 150 ms from standstill to rated speed.
Supports 12 V power supply system with up to 250 W automotive BLDC/PMSM motor control system
Supporst BLDC/PMSM sensorless FOC control, both dual shunt and single shunt
Robust and fast start-up, meeting the strict start-up condition ❮ 150ms from standstill to rated speed
Crossing the current I/F start-up and initial position detection algorithm ensures successful start-up
Board tested against supply voltage changing, load changing, speed command jumping and temperature rising
Supports multiple diagnoses and protection strategies using the robust gate driver unit (GDU); also supports over-voltage (OV), under-voltage (UV), short- and over-current (OC), over-temperature (OT) and stall detection
Supports user-defined speed commands from PWM/FreeMASTER/LIN
