600V High Voltage 3-phase Motor Driver ICs
SCM1270MF Series
Data Sheet
Description
Package
The SCM1270MF series are high voltage 3-phase
motor driver ICs in which transistors, pre-driver ICs
(MICs), and bootstrap circuits (diodes and resistors) are
highly integrated.
DIP33
Pin Pitch: 1.27 mm
Mold Dimensions: 47 mm × 19 mm × 4.4 mm
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
