LB1997
Three-Phase Brushless Motor Driver
for CD-ROM Spindle Drive
Monolithic Digital IC
The LB1997 is a three-phase brushless motor driver
especially suited for CD-ROM spindle motor drives.
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 effect of
this resistor reduces internal current drain 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
V type control/single-side control switching pin allows
CLV and CAV operation.
