Ordering number : ENN*6181A LB11996,11996H Monolithic Digital IC LB11996,11996H Three-Phase Brushless Motor Driver for CD-ROM Spindle Motor Driver Preliminary Features * 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 loses 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 * Built-in Hall power supply * Built-in thermal shutdown circuit * 1 Hall FG/3 Hall FG switchable * Supports 3.3V DSP Package Dimensions unit: mm 3227-HSOP24 [LB11996] 15.3 4.3 24 0.3 0.65 7.9 2.25 2.5max 0.25 13 1 0.3 0.8 12 0.85 0.1 SANYO : HSOP24 unit: mm 3234-HSOP28HC [LB11996H] 15.3 0.65 6.2 2.7 28 15 1.3 1 0.25 0.8 0.3 1.3 0.85 2.5max 2.25 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.
