Ordering number : EN5977A LB1996 Monolithic Digital IC LB1996 Three-Phase Brushless Motor Driver for CD-ROM Spindle Drive Overview The LB1996 is a 3-phase brushless motor driver especially suited for CD-ROM spindle motor drives. Package Dimensions unit: mm 3227-HSOP24 [LB1996] 15.3 4.3 0.3 Allowable power dissipation, Pd max – W • Current linear drive • Control V type amplifier • Separate power supply for output upper side bias circuit allows low output saturation by boosting this power supply only (useful for 5V power supply types). • Upper side current detection technique reduces loss voltage of current detection resistor. Voltage effect of this resistor reduces internal power dissipation of IC. • Built-in short braking circuit • Built-in reverse blocking circuit • Hall FG output • Built-in S/S function • Built-in current limiter circuit • Built-in Hall power supply • Built-in thermal shutdown circuit • 1 Hall FG/3 Hall FG switchable 0.65 7.9 2.25 2.5max 0.25 Functions 24 13 1 0.3 0.8 12 0.85 0.1 SANYO : HSOP24 2.0 1.9 Pd max – Ta With substrate 1.6 1.2 0.8 IC only 0.4 0 –20 0 Ambient temperature, Ta – °C 20 40 60 75 80 1.3 10.5 100 Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.
