... Ordering number : ENA1801 LV8829LF Overview The LV8829LF is a PWM-type driver IC designed for 3-phase brushless motors. It enables the rotational speed to be controlled by inputting an external PWM pulse signal and varying the duty factor. The IC incorporates a latch-type constraint protection circuit. Features • max = 1.5A (built-in output Tr) • ...

... The HB pin is used for cutting off the current flowing in the Hall elements during standby (for saving electricity). The output from the HB pin is set to OFF in the following cases. • When the S/S pin STOP state • When 0% duty is detected at the PWMIN pin input LV8829LF ( Constant-voltage Output No ...

... Power Saving Circuit (Start/Stop circuit) To save power when the LV8829LF is in the stop state, most of the circuit is stopped, aiming at reducing current consumption. If the Hall bias pin is used, the current consumption in the power-saving mode will be approximately 700μA. Even in the power-saving mode regulator voltage is output. Also, in the power-saving mode, the short break state ...
