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)
