Equivalent Circuit Diagram
LB1694N
Supplies power to all circuits except output
block.
Sets the C pin charge/discharge current.
Sets the output off time and output current
neglect time during current limiter operation.
Output pin 1
Output pin 2
Output pin 3
Output current detection pin. By inserting
resistor R
output current is detected as voltage. The
output current is limited to a current value set
by V
Power supply pin providing output.
GND for other than output.
The minimum potential of output transistor is
the RF pin voltage.
Forward/reverse control pin.
Hall device input pin.
