The HIP4011 motor driver is intended for three phase Brushlessmotor control at continuous output currents up to 3A. Itaccepts inputs from buffered Hall effect sensors and drivesthree motor windings, regulating the current through anexternal current sensing resistor, according to an analogcontrol input. Output “freewheeling” diodes are built in andoutput dv/dt is limited to decrease the generated EMI.Thermal and current limiting are used to protect the devicefrom locked rotor conditions. A brake control input forces alloutputs to ground simultaneously to provide dynamicbraking, and an internal voltage sensor does the same whenthe supply drops below a predetermined switch point. Powerdown braking energy is stored in an external capacitor.
