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
