LV8850GA: Three-Phase sensorless FAN Motor Pre-Driver
LV8850GA is a pre-driver IC which is three-phase, sensorless and drives with PWM. LV8850GA drives without a hole sensor, which is suitable for driving high-current motor which requires high reliability and long life.
特性- VCC+7V charge pump booster circuit for output drive
- Integrated Synchronous Rectifier circuit (Selected by SYNSEL pin)
- PWM or DC input signal is selectable (Selected by CTLSW pin)
- Adjustable PWM frequency (By the external capacitor at DC input mode)
- Integrated Current Limit circuit (highly accurate detection by using sensing (RFGND) pin for monitoring)
- Integrated Forward / Reverse rotation switch circuit (Selected by F/R pin)
- Integrated Lock Protection circuit with auto-recovery
- Output Lock Protection signal (RD pin) / Output 1-hole FG signal (FG pin)
