Three-Phase Brushless Motor Driver
for CD-ROM Spindle Motor Driver
Monolithic Digital IC
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
