Sample Application Circuit
Hall input voltage range: 2.2 to (V
CC
– 0.7) V DC
70 mV p-p to 300 mV p-p AC
Truth Table
Input: “H” indicates that the input phase 1 is at least 0.2 V higher than phase 2.
“L” indicates that the input phase 1 is at least 0.2 V lower than phase 2.

FC
Frequency characteristics correction
Oscillation in the current control closed loop can be prevented
by inserting a capacitor between this pin and VREF.

Ground for the output transistor
The output current can be detected as a voltage by inserting the
resistor Rf between this pin and ground to provide fixed current
drive. The current limiter also operates by detecting this voltage.
Continued on next page.
However, note that certain motors may require output capacitors to prevent oscillation.
