LB1998
Overview
The LB1998 is a three-phase brushless motor driver especially suited for CD-ROM spindle motor drives.
Functions
Current linear drive
Control V type amplifier
Top side current detection technique reduces loss
voltage of current detection resistor. Voltage effect of
this resistor reduces internal current drain of IC.
Built-in current limiter circuit
Built-in reverse blocking circuit
Hall FG output
Built-in 1 Hall FG/3 Hall FG switching circuit
Built-in short braking circuit
Built-in Hall bias cicuit
Built-in thermal shutdown circuit
Built-in S/S function
Built-in 3 mode gain switching function ensures
compatibility with 8/12 cm CAV and CLV discs
