The new SCM1270MF series from Sanken Electric are high-voltage 3-phase motor driver ICs in which IGBTs, pre-driver ICs, and bootstrap circuits (diodes and resistors) are highly integrated. These 600V devices can run on a 3-shunt current detection system and optimally control the inverter systems of medium-capacity motors that require universal input standards.
In addition, these ICs have a temperature sensing function that can output analog voltage according to the temperature of the device. By monitoring this temperature, it can provide optimal control, taking into account the thermal condition of the system.
These IGBT-based 600V motor drive ICs are offered with four current ratings, 10A (SCM1271MF), 15A (SCM1272MF), 20A (SCM1274MF), and 30A (SCM1276MF). They are designed for use in applications such as refrigerator compressor motor drives, air conditioner compressors, washing machine main motors, and general fan and pump motor drives.
Features include: 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 (22Î©); CMOS-compatible Input (3.3 V or 5 V); Bare Lead Frame: Pb-free (RoHS compliant); Isolation Voltage: 2500 V (for 1 min); UL-recognized Component (File No.: E118037); Fault Signal Output at Protection Activation; Undervoltage Lockout for Power Supply, High-side (UVLO_VB) with Auto-restart and Low-side (UVLO_VCC) with Auto-restart; Overcurrent Protection (OCP) with Auto-restart; and Simultaneous On-state Prevention with Auto-restart.
