Output current detection
Connect a resistor(Rf) between this pin and ground.
Set with the maximum output current IOUT = 0.5/Rf.
Output pin (external TR drive output)
Duty control made on UH, VH, and WH sides.
Power supply (output and Hall input blocks). Normally used
with the 12 V power supply. Connect to VCC2 and VREG
for application with the 5 V single power supply. Connect a
capacitor between this pin and GND for stabilization.
Hall amplifier input.
IN+ > IN– is the input high state,
and the reverse is the input low state.
Connect a capacitor between the IN+ and IN– inputs if there
is noise in the Hall sensor signals.
