Manufacturer:HOLTEK Description:PWM control function Motor speed can be controlled by inputting the 0/5-V PWM signal to the PWM pin. When PWM control is provided, normal operation and short brake operation are repeated. If the upper and lower power transistors in the output circuit were ON at the same time, a penetrating current would be produced. To prevent this current from being produced, a dead time of 300 ns (design target value) is provided in the IC when either of the transistors changes from ON to OFF, or vice versa. Therefore, PWM control by synchronous rectification is enabled without an OFF time being inserted by external input. Note that a dead time is also provided in the IC at the time of transition between CW and CCW or between CW (CCW) and short brake mode, thereby eliminating the need for an OFF time. |
