H-Bridge Driver Mute Function Brake function assigned CH1, mute function assigned other channels. normal operation when BRAKE (high when mute on), enters brake mode. normal operation when MUTE2 (high when mute on). CH3,4 normal operation when MUTE34 high (low when CH3,4 mute on). VREF Drop Mute When voltage impressed VREF terminal 1.0V (Typ.) less, impedance driver output becomes "high". Thermal Shutdown chip temperature rises above then thermal shutdown (TSD) circuit activated output current cut. When chip temperature dropped 100oC, then output current begins flow.
