PWM variable speed mode
1. Full standby (low power) mode
When VCONT is set to 0 to 0.5V, the LB11965M goes to a low power mode (2mA, typical) in which the 5VREG power supply
will be at 0V and bias will not be provided to the Hall sensor, CPWM, and other elements.
2. Standby mode
When VCONT is set to 0.9 to 1.1V, the 5VREG system turns on and the CPWM oscillator starts to operate.
However, while the low side transistor is driven in this mode, the high side transistor will not be turned on. As a result, the motor
will remain stopped.
3. PWM variable speed mode
The PWM signal is controlled by comparing the CPWM oscillation voltage that cycles between 1.2V and 3.8V and the VCONT
voltage.
When the VCONT voltage is higher, the high and low side transistors are turned on, and when the VCONT voltage is lower, the
high side transistor is turned off and the coil current is regenerated through the low side transistor. Thus the output on duty
increases as the VCONT voltage becomes higher, the coil current increases, and the motor speed increases.
Rotation speed feedback is provided by the FG output.
If VCONT is increased slowly, the motor will start to turn with a low startup current.
4. Full-speed mode
In this state, the output is on 100% of the time and the IC provides full drive.
