Hall amp. circuit
The Hall amp is a high-gain amp. The input sensitivity is 20 mV
does not exceed 400 mV
The common-mode voltage V
CW/CCW/Stop control circuit
In Reverse mode, the control input (3ST) voltage range is V
the IC GND as possible (see the application circuit diagram).
Similarly, in Stop mode, keep the voltage as close to the IC V
In Forward mode, Toshiba recommend an input voltage of V
Output circuits
The output circuit uses voltage control where the upper and lower output transistors are saturated and the
output current is controlled by the V
output circuit.
Thermal shutdown circuit
The circuit turns off output when T
