LV8862JA-AH ON Semiconductor

LV8862JA Bi-CMOS LSI www.onsemi.com Single-phase FAN Motor Driver Overview LV8862JA is a driver IC used for single-phase fan motor. High-efficiency and low-noise are realized by reducing reactive power using Silent PWM. This ICs feature is low on-resistance 0.6 & High-efficiency. Therefore, it is optimal for high power fan motor and home appliance equipment. Feature Single-phase full wave operation by Silent PWM drive Speed is controllable by PWM input SSOP16 (225mil) Hall bias output pin Integrated Quick Start Circuit FG (rotation detection)/ RD (lock detection) output pin (open drain output) Integrated current limiter circuit (limit at Io=500mA with RL=0.5 connection, limit value is determined based on Rf.) Integrated lock protector circuit and automatic recovery circuit Integrated thermal shut-down (TSD) circuit Typical Applications Fan motor units Desk top PCs Refrigerator Projectors Specifications Absolute Maximum Ratings at Ta = 25C, GND = 0V Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCCmax 20 V OUT pin output current IOUTmax 1.5 A Output withstand VOUTmax 20 V RD/FG output pin withstand VRD/FG max 18 V RD/FG output maximum current IRD/FG max 10 mA RGL output maximum current IRGL max 5 mA HB output maximum current IHB max 10 mA 6 PWM input pin withstand VPWM max V On a specified board *1 0.8 Allowable power dissipation Pd max W *2 Operating temperature Topr 40 to + 95 C Storage temperature Tstg 55 to + 150 C *1 Specified board: 76.1mm x 114.3mm x 1.6mm, glass epoxy board *2 Do not exceed Tjmax=150 C Stresses exceeding those listed in the Maximum Ratings table may damage the device.
