Functional Description
• Hall amp. circuit
Ha+

TA8492P/PG
The Hall amp is a high-gain amp. The input sensitivity is 20 mVp-p (min). Make sure that the input amplitude does not
exceed 400 mVp-p.
The common-mode voltage VCMRH 2.0 to VCC − 3.5 V.

• CW/CCW/Stop control circuit
3ST
In Reverse mode, the control input (3ST) voltage range is VRV = 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 VCC as possible.
In Forward mode, Toshiba recommends that the input voltage be VCC/2.
• Output circuit
VS
La
La
(Upper)
(Lower)
The output circuit uses voltage control where the upper and lower output transistors are saturated and the
output current is controlled by the VS voltage. To reduce switching noise, connect a snubber capacitor to the
output circuit.
• Thermal shutdown circuit
The circuit turns off output when Tj = 160°C (typ.) (according to design specification)
