1 / 6 page Monolithic Digital IC Ordering number : EN4455B O3097HA (OT)/30395TH (OT) No. 4455-1/6 SANYO Electric Co.,Ltd. Semiconductor Bussiness Headquarters TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110 JAPAN Three-Phase Brushless Motor Driver IC LB1881M 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. 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 Package Dimensions unit: mm 3073A-MFP30S SANYO: MFP30S [LB1881M] Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit VCC1 max 7 V Supply voltage VCC2 max 12 V VS max VCC2V Output applied voltage VO max VS + 2 V Input applied voltage VI max All input pins VCC1V Output current IO max 1.0 A Allowable power dissipation Pd max 1.0 W Operating temperature Topr –20 to +75 °C Storage temperature Tstg –55 to +150 °C Allowable Operating Ranges at Ta = 25°C Parameter Symbol Conditions Ratings Unit VCC1VCC1 ≤ VCC2 4.0 to 6.0 V Supply voltage VCC2 4 to 10 V VS Up to VCC2V |
