Function
Remarks
1
ELCL
External current
limit - continuous
External voltage scales down rated value.
•
Voltage range: 0 V to 3.75 V (3.75 V = rated Ic)
•
Internally limited to rated value
2
ECLRET
Current limits
return
Return for current limits signals.
3
ECLP
External current
limit - peak
External voltage scales down rated value.
•
Voltage range: 0 V to 3.75 V (3.75 V = rated Ip)
•
Internally limited to rated value
4
CGCRET
Current gain
change return
Return for CGC signal.
5
CGC
Current gain
change
Shorting this pin to the CGCRET pin (J2/4) reduces the
proportional gain (P) of the current loop by 70%.
6
CFM
Current feedback
multiplier
Shorting this pin to pin J2/5 (CGC) multiplies the current
feedback signal by 2.
7
LM
Latch mode
Latch mode input.
8
LMRET
Latch mode
return
Return for Latch mode (LM).
9
EN+
Enable ( + )
Positive voltage input of "Amplifier Enable” function. To
enable operation of the amplifier, the opto must be
switched on by applying voltage between this pin (+) and pin
J2/10 (-).
The opto is isolated from the amplifier. See Figure 1.
•
Minimum “On” voltage: 3 V , current consumption
0.6 mA.
•
Maximum “On” voltage: 15 V , current consumption
5.4 mA.
10
EN-
Enable (-)
Negative voltage input of “Amplifier Enable” function. Opto
is isolated from the amplifier. For details, see pin J2/9.
