Example:
A typical -48V supply may vary from -36 to -72V.
Therefore:
V BUS -48V

Biasing the ISL6116
Table 3 gives typical component values for biasing the
ISL6116 in a ±48V application. The formulas and
calculations deriving these values are also shown in the
following equations.

12V Zener Diode, 50mA Reverse Current
P RCL = I C ( V BUS ( MAX ) – 12 )
When using the ISL6116 to control -48V, a Zener diode
may be used to provide the +12V bias to the chip. If a
Zener is used then a current limit resistor should also
P RCL = ( 0.015 ) ( 72 – 12 )
P RCL = 0.9W [ TypicalValue = 1W ]

be used. Several items must be taken into account
when choosing values for the current limit resistor
(R CL ) and Zener Diode (DD1):
? The variation of the V BUS (in this case, -48V
nominal)
? The chip supply current needs for all functional
conditions
? The power rating of R CL .
? The current rating of DD1
