SCM1274MF

600 V High Voltage 3-phase Motor Drivers SCM1270MF Series Data Sheet Description The SCM1270MF series are high voltage 3-phase motor drivers in which transistors, pre-drive circuits, and bootstrap circuits (diodes and resistors) are highly integrated. These products can run on a 3-shunt current detection system and optimally control the inverter systems of medium-capacity motors that require universal input standards. Features ● Temperature Sensing Function ● In Case of Abnormal Operaion, All Outputs Shut Down via the FO1, FO3, and SD Pins Connected Together ● Built-in Bootstrap Diodes with Current Limiting Resistors (22 Ω) ● CMOS-compatible Input (3.3 V or 5 V) ● Pb-free (RoHS Compliant) ● Isolation Voltage: 2500 V (for 1 min) UL-recognized Component (File No.: E118037) ● Fault Signal Output at Protection Activation ● Protections Include: Undervoltage Lockout for Power Supply High-side (UVLO_VB): Auto-restart Low-side (UVLO_VCC): Auto-restart Overcurrent Protection (OCP): Auto-restart Simultaneous On-state Prevention: Auto-restart Typical Application VCC INT LIN1 HIN1 VFO RFO CFO U1 SCM1270MF Series FO1 1 2 OCP1 3 LIN1 4 COM1 5 HIN1 6 VCC1 MIC1 Controller power supply Thermal LIN2 HIN2 DZVT RVT CBOOT1 7 VB1 8 HS1 SD 9 10 VT 11 LIN2 12 COM2 13 HIN2 14 VCC2 MIC2 Controller LIN3 HIN3 CBOOT2 15 VB2 16 HS2 FO3 17 18 OCP3 19 LIN3 20 COM3 21 HIN3 22 VCC3 MIC3 CBOOT3 23 VB3 24 HS3 A/D CO COM LS1 33 U 32 31 LS2 30 V 29 28 LS3 27 W 26 VBB 25 RO DRS M VDC RS P...
