Abstract: A power cutter, an oscillator, a counter, a S-R latch, and a Hall bias are further disposed inside a DC motor driving circuit so that current consumption of the DC motor driving circuit is reduced significantly under a standby mode. When the counter detects that a received pulse width modulation signal stays at a low electrical level over a predetermined time, the counter triggers the S-R latch so as to activate a disabling signal of the power cutter for shutting down most elements until the pulse width modulation signal returns to a high electrical level. With the aid of the built-in Hall bias, space for externally coupling the Hall bias is saved, and moreover, a Hall sensor retrieves a dynamically-adjusted power and currents so that remarkable current consumption is saved under a standby mode.
