Pin Function
Supplies power to all circuits except output
block.
Sets the C pin charge/discharge current. In
current limiter operation when the motor is
locked, the charge current set by this pin
becomes charge current ICL1 for the C pin.
Sets the output off time and output current
neglect time during current limiter operation.
Sets the C pin charging current.
In current limiter operation when the motor is
rotating, the sum of the current set by this pin
and the current ICL1 set by the R1 pin
becomes charge current ICL2 for
the C pin.
Output pin 1
Output pin 2
Output pin 3
Output current detection pin. By inserting
resistor Rf between this pin and GND, the
output current is detected as voltage. The
output current is limited to a current value set
by VRF/Rf (current limit operation).
Power supply pin providing output
Regulator pin.
When using a single power supply (VM), VCC
(5.2 V) is supplied by adding an external
transistor.
The recommended transistor is the
2SD1724T. If a regulator is not used, this pin
should either be open or grounded.
GND for other than output.
The minimum potential of output transistor is
the RF pin voltage.
Forward/reverse control pin.
