LB11997H

Ordering number : ENN*6231 LB11997H Monolithic Digital IC LB11997H Three-Phase Brushless Motor Driver for CD-ROM Spindle Drive Preliminary Overview The LB11997H is a 3-phase brushless motor driver especially suited for CD-ROM spindle motor drives. Package Dimensions unit: mm 3234-HSOP28H-C [LB11997H] 15.3 28 15 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 drop caused by 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 (selectable, 2 steps) Built-in Hall power supply Built-in thermal shutdown circuit Supports 3.3V DSP 0.65 0.25 Functions 6.2 2.7 1 0.85 0.8 0.3 2.5max 0.1 2.25 SANYO : HSOP28H-C 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.
