OUTPUT CURRENT RATING
The PWS750-1U oscillator contains soft start circuitry to
protect the FETs from high inrush currents during turn on.
The internal input current limit is 250mA peak to prevent
thermal overload of the MOSFETs. The maximum output
rating is
±
30mA. Total current, which can be drawn from
each isolation channel, is the total of the power being drawn
from both the +V and –V outputs. For example, if one output
is not used, then maximum current can be drawn from the
other output. In all cases the maximum current that can be
drawn from any individual channel is:
|+I
OUT
| + |–I
OUT
| < 60mA
It should be noted that many analog circuit functions do not
simultaneously draw equal current from both the positive
and negative supplies.
When multiple channel operation is used, the maximum
current of all channels must be reduced to prevent the
overcurrent limit to trip. Alternately, bypass the overcurrent
by leaving the V
D
pin of the PWS750-1U open and connect-
ing the V
D
pin of the PWS750-2U directly to the supply.
HIGH VOLTAGE TESTING
Burr-Brown Corporation has adopted a partial discharge test
criterion that conforms to the German VDE0884 optocou-
pler standard. This method requires that less than 5pC partial
discharge crosses the isolation barrier with 1200Vrms 60Hz
applied. This criterion confirms transient overvoltage (1.5
x
750Vrms) protection without damage to the PWS750-2U or
PWS750-4U. Life test results verify the absence of high
voltage breakdown under continuous rated voltage and maxi-
mum temperature.
