4.2.2 External
Resistor
Connect an external resistor between terminal J1/9 (ECLC) and terminal J1/8 (ECLRET).
The resistor value is given by:
The resistor value is given by:
0 < RECLC < 36.4 K (1/8 Watt)
At RECLC greater than 36.4 K, the current limit will be internally clamped to the nominal
value.
value.
IC(nom) is the nominal continuous current limit of the amplifier.
4.2.3
External Current Limit - Peak (ECLP)
The peak current limit of the Dragonfly and Butterfly amplifiers can be scaled down by an
external voltage or by an external resistor connected between pin J1/14 (ECLP) and J1/8
(ECLRET).
external voltage or by an external resistor connected between pin J1/14 (ECLP) and J1/8
(ECLRET).
4.2.4 External
Voltage
An external positive voltage (0 to 3.75 V) to terminal J1/14 (ECLP) in reference to terminal
J1/8 (ECLRET) will control the peak current limit from zero to Ip(nom).
J1/8 (ECLRET) will control the peak current limit from zero to Ip(nom).
The voltage is internally clamped to 3.75 V whenever the external VECLP is higher than 3.75 V.
The external voltage source must be able to source/sink at least
±0.2 mA.
The maximum absolute VECLP allowed to be connected is 5 V.
