HITACHI는 40W ~ 120W급 Brushless DC motor 제어용 Driver IC를 공급하고 있습니다.

Product Feature

- Integrated, Single-Chip Direct BLDC Motor Driver IC

- Integrated Charge Pump - Creates 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 

- Latch-Up Free monolithic IC - Built with a high                voltage Dielectric Isolation (DI) process 

- Simple Variable Speed Control via a single (VSP)            analog input

- PWM duty cycle generator provides a 0% to 100%          speed control range

- BOTTOM Arms switch at up to 20kHz via an on-chip      OSC/PWM

- On-Chip 7.5VDC regulator (CB) with a guaranteed        Min load (25mA)

- Low Stand-By power

- An all output IGBT Shut-OFF function

- Enhanced protection functions such as over-current      protection

- Suitable for sine wave drive with or without a                  position sensor (position sensorless control)

- Sine wave control is realized by using this IC with a          microprocessor
