LB11995H

Ordering number : EN6116 LB11995H Monolithic Digital IC LB11995H Three-Phase Brushless Motor Driver for CD-ROM Spindle Drive Overview The LB11995H is a 3-phase brushless motor driver especially suited for CD-ROM spindle motor drives. Package Dimensions unit: mm 3234-HSOP28H-C [LB11995H] 15.3 Functions 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 7.9 28 15 0.65 0.25 6.2 2.7 1 0.85 0.8 0.3 2.5max 0.1 2.25 SANYO : HSOP28H-C Allowable power dissipation, Pd max – W 2.0 1.9 Pd max – Ta 1.6 With specified substrate (114.3mm×76.1mm×1.6mm) 1.14 1.2 0.8 IC only 0.48 0.4 0 –20 0 Ambient temperature, Ta – °C 20 40 60 75 80 1.3 10.5 4.9 100 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 applicat...
