Power supply pin for applying output
Power supply pin for applying voltage to each section other than output section.
The control point of control voltage is at approximately 1/2 of this voltage.
This voltage must be stabilized to be free from ripple, noise, etc.
Output current detect pin. By connecting R
f
across this pin and GND pin, output
current is detected as voltage.
Pin for fetching current (voltage) detected with R
f
.
By connecting a resistor across C
D
pin and R
f
, speed control start voltage can be
fine-adjusted.
Overcurrent protection pin.
Voltage being lower than that on C
D
pin is taken to be identical to overcurrent
flow, causing output to be cut off. Off-state is held.
For example, if STOP pin is set to 1.5V for R
f
=1
, approximately 1.5A or more
flows at output, causing output to be cut off.
Frequency characteristic compensation pin.
Closed loop oscillation in current-controlled system (including motor, F/V
converter) is stopped.
Speed/phase control pin.
Control starts at approximately 1/2 of V
CC
2.
Control is of current-controlled type that controls output current.
For R
f
=1
, LB1620 closed loop has gm of 0.44A/V typ, which can be adjusted by
varying R
f
.
GND for other than output.
Minimun potential of output transistor is at R
f
pin.
Forward/reverse rotation control pin.
By setting this pin to "H" (more than 2V) / "L" (less than 0.3V), truth value is
changed to perform forward/reverse rotation.
