3) Control input conditions
The input threshold voltage has a positive temperature coefficient and is expressed by:
Technical Note
Δ VIH
Δ T
= +2.8mV / ℃
Δ VIL
Δ T
= +1.6mV / ℃
The input pin is pulled up at about 15k ? .
Set input voltage with care not to exceed the maximum input voltage (internal voltage regulator).
BA6247FP-Y ··· 6V
BA6238A ··· 5V
4) Switching of rotating direction (FWD/REV)
When the rotating direction is changed over by the motor rotating condition, switch the direction after the motor is
temporarily brought to the BRAKE condition or OPEN condition. It is recommended to keep the relevant conditions as
follows:
via BRAKE: Longer than braking time*.
(* the time required for the output L terminal to achieve potential below GND when brake is activated.)
The motor in no drive might be influenced momentarily because the all driver outputs low at the brake.
