FEATURES
q 3.3V DSP available. q Low saturation voltage. q By taking advantage of the bootstrap function, the saturation voltage can be lower. q There are two motor power supplies. Vm12 CH1, 2 motor power supply-1 Vm3 CH3 motor power supply-2 q 7V power-supply is possible (Vm12 = 12V and MGND12 = 5V) q Flexible Input amplifier setting. (It enables PWM control.) q CH1 and CH2 can act in the Current Control mode. q Low cross-over distortion. q Wide supply voltage range. (4.5V – 13.2V) q Including Thermal Shut Down circuit. q Including 2 Operational Amplifiers. q Including Mute circuit (2 lines).
