3-Phase BLDC Motor Driver IC P1/16 ECN30204 The ECN30204 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 450VDC) directly rectified from AC power line (up to 230VAC) for downsizing a system and reducing power consumption. Description · Integrated, Single-Chip 3-Phase BLDC Motor Driver IC. · Integrated Charge Pump – Constant TOP Arm bias independent of motor speed. · Integrated 3-Phase Brushless (Electronic) commutation via external Hall ICs. · Integrated 3-Phase 6-IGBT Motor Bridge with on chip Free-Wheeling diodes. · Pinout and Board Layout are compatible with the existing Hitachi ECN3022. · Maximum Ratings 500VDC/1.5A. · Latch-Up free monolithic IC built with a high voltage Dielectrically Isolated (DI) process. · Available in 3 package types with built-in heat sink (Tab). Functions and Features · Vs Operating Voltage Range from 15VDC up to 450VDC. · Simple Variable Speed Control via a single (VSP) analog input. · PWM duty cycle generator provides the 0% to 100% speed control range. · Tachometer – Generates the (RPM/60)× (P/2)× 3 Hz speed signal (FG). · BOTTOM Arms switch at up to 20kHz via an on-chip OSC/PWM. · On-Chip 7.5VDC regulator (CB) with the guaranteed extern...
