HALL AMPLIFIER INPUT AND COMMUTATION
The relationship between the hall amplifier inputs voltage and the motor current outputs is shown in Figure 2.

HALL AMPLIFIER INPUT SENSITIVITY SELECT
Figure 3 shows the hall amplifier input sensitivity select function.
You are able to select a sensitivity of a hall amplifier out of two
levels which is suitable for the hall elements type.
If the output minimum level of the hall elements is lower than
50mVp-p, please connect the MODE4 pin to external GND. In this
case, the output current changes shaply. If the output minimum
level of the hall elements is higher than 50mVp-p, please make the
MODE4 pin open, then the output current is commutated softly.
We recommend that the output level of the hall elements be set
between 80mVp-p and 120mVp-p, and the MODE4 pin is an open.

SLEEP MODE FUNCTION

Figure 4 shows the sleep mode function. If the
be open or low, the motor drive outputs have high impedance and
the motor stops. Then, the IC bias current will be a slight current
(please refer to the electrical characteristics), and the hall bias
output will be cut off. When the
