ACTIVE BIAS CONTROLLER
Pin Number
Function
Description
Interface Schematic
21
VGATE
Gate Control pin for external amplifier. Connect to the gate
(base) of the external amplifier. In order to guarantee stabil-
ity, a 10礔 capacitor should be connected between the
gate (base) terminal of the external amplifier and GND as
close to the amplifier as possible.
22, 23
VDRAIN
Drain voltage. Should be connected to the supply
terminal of the external amplifier. A minimum 100 nF
capacitor has to be placed close to the external amplifier to
improve load regulation.
25
ISENSE
To adjust the bias current of the external amplifier connect
a resistor (Rsense) from ISENSE pin to GND. Use Eqn.4 to
determine the required Rsense value.
26
ALML
A high precision resistor (e.g. 0.5%, ?5 ppm TCR) to GND
is needed. The value of the resistor sets the threshold
value for under current alarm. Please refer to the Over/
Under Current Alarm section for a detailed explanation.
27
ALMM
A high precision resistor (e.g. 0.5%, ?5 ppm TCR)
between ALML and ALMM is needed. The total external
resistance from ALMM pin to GND should always be equal
to 5 k&. Please refer to the Over/Under Current Alarm
section for a detailed explanation.
28
ALMH
A high precision resistor (e.g. 0.5%, ?5 ppm TCR) to
ALMM pin is needed. The value of the resistor sets the
threshold value for over current alarm. Please refer to
the Over/Under Current Alarm section for a detailed
explanation.
