SCM1276MF

Overview

The SCM1276MF is a high-voltage three-phase motor driver IC from the SCM1270MF series, designed for brushless DC (BLDC) and fan motor applications. It integrates IGBT power devices, pre-driver ICs, bootstrap circuits, and current sensing capabilities within a single package. The device supports parallel interface control with input thresholds of 3.3V or 5.0V. It features overcurrent protection (OCP), under-voltage lockout (UVLO), and temperature monitoring functions. The output configuration consists of three half-bridges capable of handling up to 30A, operating with a supply voltage range of 13.5V to 16.5V.

Feature Summary

• Integrates high-voltage IGBT power stages, pre-drivers, and bootstrap diodes/resistors in a single package
