SCM1243MF – 600V / 15A Three-Phase Motor Driver Power IC (IGBT, 3-Shunt Support)

SCM1243MF is a 600-volt, 15-amp high-voltage power IC designed for efficient three-phase inverter motor control. The device integrates IGBT power elements, pre-driver logic, and bootstrap circuitry into a single compact solution—ideal for medium-capacity motors that operate from universal AC input.

Its architecture supports three-shunt current sensing, enabling precise torque and speed control in inverter-driven appliances. With 3.3–5V CMOS input compatibility, the IC interfaces easily with common microcontrollers.

For system reliability, SCM1243MF includes extensive protection features, including: under-voltage lockout on both high-side and low-side supplies, over-current protection with auto-restart, simultaneous-on prevention, and thermal shutdown. During fault events, a dedicated fault-output pin simplifies system diagnostics.

With 2,500V isolation and UL component recognition, the SCM1243MF delivers safe operation in high-voltage appliance environments.
