Function

Remarks

CREF+

Current command

input ( + )

Positive input of a differential amplifier:

 Input operating voltage range: ±3.75 V

 Maximum input voltage: ±20 V

(see section 4.1)

 Maximum common mode voltage: ±6 V

(referred to as CMRET)

 Differential input impedance: 40 kΩ

CREF-

Current command

input ( - )

Negative input of a differential amplifier.

Specification as for pin J1/1.

ECLC

External current

limit - continuous

External voltage scales down the rated value:

 Voltage range: 0 V to 3.75 V (3.75 V = rated Ic).

 Internally limited to the rated value.

ECLP

External current

limit – peak

External voltage scales down the rated value.

 Voltage range: 0 V to 3.75 V (3.75V = rated Ip).

 Internally limited to the rated value.

ECLRET

Current limits

return

Return for the current limit signals.

Current monitor Analog output with a scale of ± 3.9 V for ± Ip.

Output resistance: 10 kΩ

CMRET

Current monitor

return

Return for the current monitor (CM) signal.

CGC

Current gain

change

Shorting this pin to the CGCRET pin (J1/9)

reduces the proportional gain (P) of the current

loop by 70%.

CGCRET

Current gain

change return

Return for CGC signal

CFM

Current feedback

multiplier

Shorting this pin to pin J1/8 (CGC) multiplies

the current feedback signal by 2.
