1 / 14 page 72413NK 20130626-S00001 No.A2205-1/14 Semiconductor Components Industries, LLC, 2013 July, 2013 http://onsemi.com LV8850GA 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 Ratings Unit Maximum Supply voltage VCC max VCC pin 18 V Maximum VG voltage VG max VG pin 23 V Maximum RD/FG pin voltage VFG max RD, FG pin 18 V Maximum RD/FG pin current IFG max RD, FG pin 5 mA Maximum Output pin voltage1 VO max1 UH, VH, WH pin 23 V Maximum Output pin voltage2 VO max2 UL, VL, WL pin 6 V Maximum Output pin current IO max UH, VH, WH, UL, VL, WL pin 30 mA Maximum Input pin voltage VL max SOSC, LIM, VCTL, PWMOSC, CSDOSC 6 V Maximum VREG pin current IVREG max VREG pin 5 mA Allowable power dissipation2 Pd max Mounted on a board. *1 1.2 W Operating temperature Topr – 40 to 95 deg. Storage temperature Tstg – 55 to 150 deg. Junction temperature Tj max 150 deg. *1: Specified board: 76.1mm x 114.3mm x 1.6mm, glass epoxy board Ordering number : ENA2205 Bi-CMOS IC Three-Phase sensorless FAN Motor Pre-Driver Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
