S12ZVM-EFP

S12ZVM-EFP is a Reference Design (RD) based on NXP’s S12ZVML128 high-performance and integrated automotive-grade MCU which integrates a 100MHz S12Z core, gate driver unit, power regulators and LIN PHY. This RD is designed to deliver a total solution for BLDC or PMSM fuel pump application in a 12V automotive system. The Reference Design Board (RDB) has hall/encoder interface for position sensor support. For debug purposes, not only BDM and FreeMASTER TTL (SCI) are placed, but also the PTU monitor (PTU0/1/RE) is placed. Some other PINs, like Port AD and T and one SPI which would be used are there for reference.

• Main devices used in the RDB are: S12ZVML128 and BUK7J1R4-40H
• Supports 12V power supply system with up to 250W automotive BLDC/PMSM motor control system
• Supports BLDC/PMSM sensorless FOC control, both dual shunt and single shunt
• Robust and fast start up, meet strict start up condition < 150ms from standstill to the rated speed
• Crossing current I/F start up and initial position detection algorithm to make successful startup
• Fuel pump system passed the changing (supply voltage and load), speed command jumping
• Supports multiple diagnose and protection covering UV, OV, OT, OC, short, stall detection, etc
• Not only supports fuel pumps, but is suitable for other automotive BLDC/PMSM applications
