Features
Current linear drive Control type amplifier Separate power supply output upper side bias circuit allows output saturation boosting this power supply only (useful power supply types). Upper side current detection technique loses loss voltage current detection resistor. Voltage drop caused this resistor reduces internal power dissipation Built-in short braking circuit Built-in reverse blocking circuit Hall output Built-in function Built-in current limiter circuit (selectable, steps) Built-in Hall power supply Built-in thermal shutdown circuit Supports 3.3V
