2-phase half-wave high voltage motor pre-driver am4406/4406f data sheet 1 nov. 2009 rev. 1. 5 bcd semiconductor manufacturing limited general description the am4406/4406f are 2-phase, half-wave motor pre- drivers fabricated for fa n motors. these ics are equipped with lock shutdown and automatic restart functions. the lock shutdown function turns off the output current when the motor is under lock condition. and when the motor is unlocked, the ics will automat- ically restart and allow dc fan to run. in addition, the am4406 and AM4406F have rd and fg functions respectively. the rd function is to detect the motor status and fg function enables frequency generation. the am4406/4406f are availa ble in soic-8 package. features hall inputs with a hysteresis lock shutdown and automatic restart rotation detection (rd) output frequency generation (fg) output supply voltage: 4 to 28v output current: 70ma max. operating temperature: -40 to 95 o c applications high voltage, high current brushless dc fan power supply and switchboards communications facilities industrial equipment figure 1. package type of am4406/4406f soic-8
