ECN30204
ECN30204 is 3-Phase BLDC Motor Driver IC manufactured by Hitachi Semiconductor.
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) mutation via external Hall ICs.
- Integrated 3-Phase 6-IGBT Motor Bridge with on chip Free-Wheeling diodes.
- Pinout and Board Layout are patible 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 20k Hz via an on-chip OSC/PWM.
- On-Chip 7.5VDC regulator (CB) with the guaranteed external Min load (25m A).
- Over-Current protection is set by an external Sense Resistor (RS).
- Under-Voltage protection for TOP and BOTTOM IGBT Arms.
- All output IGBT Shut-OFF function.
