LB1927

www.DataSheet.co.kr Ordering number : EN6197C Monolithic Digital IC LB1927 Overview For Office Automation Equipment 3-phase Brushless Motor Driver The LB1927 is a 3-phase brushless motor driver well suited for drum and paper feed motors in laser printers, plain-paper copiers and other office automation equipment. Direct PWM drive allows control with low power losses. Peripheral circuitry including speed control circuit and FG amplifier is integrated, thus allows drive circuit to be constructed with a single chip. Features 3-phase bipolar drive (30V, 2.5A) Direct PWM drive technique Built-in diode for absorbing output lower-side kickback Speed discriminator and PLL speed control Speed lock detection output Built-in forward/reverse switching circuit Built-in protection circuitry includes current limiter, overheat protection, motor restraint protection, etc. Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Maximum output current Allowable power dissipation 1 Allowable power dissipation 2 Operating temperature Storage temperature Symbol VCC max IO max Pd max 1 Pd max 2 Topr Tstg T ≤ 500ms Independent IC With an arbitrary large heat sink Conditions Ratings 30 2.5 3 20 -20 to +80 -55 to +150 Unit V A W W °C °C Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, commun...
