[原创] ST L6230和STM32F302R8三相马达控制平台方案

ST公司的L6320是具有过流保护的DMOS全集成三相马达驱动器,包括有绝缘的DMOS功率晶体管和CMOS与双极电路,工作电压从8V到52V,峰值电流2.8A(1.4A RMS),工作频率高达100kHz,非常适合用在磁场定向控制(FOC)应用如BLDC马达驱动,正弦/六步驱动和磁场定向控制驱动系统.本文介绍了L6230主要特性,框图,几种典型应用电路,以及STM32 NUCLEO Pack FOC和六步马达控制平台P-NUCLEO-IHM001主要特性,框图,电路图,材料清单和PCB元件布局图.

The L6230 is a DMOS fully integrated threephasemotor driver with overcurrent protection,optimized for FOC application thanks to theindependent current senses.

Realized in BCDmultipower technology, thedevice combines isolated DMOS PowerTransistors with CMOS and bipolar circuits on thesame chip. An uncommitted comparator with open-drainoutput is available.

Available in PowerSO36 and VFQFPN-32 5x5packages the L6230 features a non dissipativeovercurrent protection on the high side powerMOSFETs and thermal shutdown.

L6230主要特性:

■ Operating supply voltage from 8 to 52 V
■ 2.8 A output peak current (1.4 A RMS)
■ RDS(on) 0.73 Ω typ. value @ TJ = 25 ℃
■ Integrated fast free wheeling diodes
■ Operating frequency up to 100 kHz
■ Non dissipative overcurrent detection andprotection
■ Cross conduction protection
■ Diagnostic output
■ Uncommitted comparator..
