plc学习机The ECN30206 is a fully integrated, single-chip BLDC motor driver that facilitates a rapid design process and low part count solution. The chip integrates BLDC Logic with a 3-Phase Inverter containing six (6) 500V rated IGBTs and a Charge Pump TOP Arm bias. To reduce motor current losses, a BLDC motor can now be driven directly from rectified 200 to 230VAC (up to 450VDC) power lines, or from any DC power bus down to 15VDC. On-Chip Brushless (electronic) commutation logic is fully integrated with analog OSC/PWM functions that permit an analog (VSP) voltage to control motor speed.
