Functional Description
Hall amp. circuit
The Hall amp is a high-gain amp. The input sensitivity is 20 mV
p-p
(min). Make sure that the input amplitude does not
exceed 400 mV

CW/CCW/Stop control circuit
In Reverse mode, the control input (3ST) voltage range is V
RV
=
0 to 0.4 V. However, keep the voltage as close to
the IC GND as possible (see the application circuit diagram).
Similarly, in Stop mode, keep the voltage as close to the IC V
CC
as possible.
In Forward mode, Toshiba recommends that the input voltage be V
CC
/2.
Output circuit
The output circuit uses voltage control where the upper and lower output transistors are saturated and the
output current is controlled by the V
S
voltage. To reduce switching noise, connect a snubber capacitor to the
output circuit.
Thermal shutdown circuit
The circuit turns off output when T
j
=
160°C (typ.) (according to design specification)
