Monolithic Digital IC
LB1999M
Three-Phase Brushless Motor Driver
for VCR Capstan Motors
Overview
The LB1999M is a 3-phase brushless motor driver that is
particularly appropriate for VCR capstan motor drivers.
Functions
· 3-phase full-wave drive
· Built-in torque ripple correction circuit (fixed correction
ratio)
· Built-in current limiter circuit and control characteristics
that include gain switching
· Upper and lower side output stage over-saturation
prevention circuit that does not require external
capacitors.
· FG amplifier with built-in Schmitt comparator
· Thermal shutdown circuit

Function
Output block power supply
Output current detection. The control block current limiter
operates using the resistor Rf connected between these pins
and ground. Also, the lower side saturation prevention circuit
and the torque ripple correction circuit operate based on the
voltages to this pin. It is especially important to note that,
since the saturation prevention level is set using this voltage,
the lower side saturation prevention circuit will become less
effective in the large current region if the value of Rf is
lowered excessively. Also, the PWR and SENSE pins must
be connected together.

impedance on Rf can be excluded by connecting this pin to
nearest ground for the Rf resistor side of the motor ground
wiring that includes Rf. (This pin must not be left open.)
Forward/reverse selection. The voltage applied to this pin
33 FR selects the motor direction (forward or reverse).
(Vth = 2.5 V at VCC = 5 V (typical))
Pin Assignment
Equivalent circuit
Note: Although the FRAME pins and
the GND pins are not connected
internally, the potentials of the
GND pins and the FRAME pins
externally be identical to assure
ground potential stability.
