APPLICATION INFORMATION
1. HALL INPUT
The input signal of the hall sensor requires more amplitude than 100mVo-p. and the operating voltage level of the
hall sensor is from 1.2V ~ VCC1-0.8V.

2. OUTPUT CURRENT DETECTION
Pin 11 is usually connected with RS (Approx. 0.5Ω), and the motor current is converted to a voltage by the RS and
provided to a feedback amplifier. Pin 12 is connected to the circuit with the ground side or RS.
