LV8850GA

Ordering number : ENA2205 LV8850GA Bi-CMOS IC Three-Phase sensorless FAN Motor Pre-Driver http://onsemi.com Overview 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. Function 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) Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Maximum Supply voltage Maximum VG voltage Maximum RD/FG pin voltage Maximum RD/FG pin current Maximum Output pin voltage1 Maximum Output pin voltage2 Maximum Output pin current Maximum Input pin voltage Maximum VREG pin current Allowable power dissipation2 VCC max VG max VFG max IFG max VO max1 VO max2 IO max VL max IVREG max Pd max VCC pin VG pin RD, FG pin RD, FG pin UH, VH, WH pin UL, VL, WL pin UH, VH, WH, UL, VL, WL pin SOSC, LIM, VCTL, PWMOSC, CSDOSC VREG pin Mounted on a board. ...
