Truth Table (loading (H bridge) section)
* 1 The output has a high impedance.
* 2 At brake, the SINK side transistor is ON (short brake).
Relation of MUTE and Power (V CC *)
*Connect V CC 1 and V CC 2 externally.
V IN 1 (VREF)-SW
(This is to minimize effects of voltage drop in internal and metal wirings.)
V LO + and V LO - are approximately on the GND level.
