3-Phase BLDC Motor Driver IC

ECN30107SP/SPV/SPR
The ECN30107 is a fully integrated BLDC motor driver IC that facilitates a rapid design
process and low part count solution. The IC integrates a commutation-logic, a PWM signal
generator, IGBTs, FWDs(Free Wheeling Diodes), a charge pump, protection circuits, etc.
The IC can drive a BLDC motor with a high voltage DC power supply (up to 185VDC)
directly rectified from AC power line (up to 115VAC). This contributes to downsizing a
system and reducing power consumption.
