LB1881M

Ordering number : EN4455B Monolithic Digital IC LB1881M Three-Phase Brushless Motor Driver IC Overview The LB1881M is a three-phase brushless motor driver IC designed for use as a camcorder capstan or drum motor driver, or as a digital audio tape player/recorder motor driver. Package Dimensions unit: mm 3073A-MFP30S [LB1881M] Features 120° voltage linear system Appropriate for portable applications, since the LB1881M reduces system power requirements by using motor voltage control for speed control. Built-in torque ripple compensation circuit Small external capacitances due to the adoption of a soft switching technique (chip capacitor). Built-in thermal shutdown circuit Built-in FG amplifier SANYO: MFP30S Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol VCC1 max Supply voltage VCC2 max VS max Output applied voltage Input applied voltage Output current Allowable power dissipation Operating temperature Storage temperature VO max VI max IO max Pd max Topr Tstg All input pins Conditions Ratings 7 12 VCC2 VS + 2 VCC1 1.0 1.0 –20 to +75 –55 to +150 Unit V V V V V A W °C °C Allowable Operating Ranges at Ta = 25°C Parameter Symbol VCC1 Supply voltage VCC2 VS Conditions VCC1 ≤ VCC2 Ratings 4.0 to 6.0 4 to 10 Up to VCC2 Unit V V V SANYO Electric Co.,Ltd.
