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.
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
be used. Several items must be taken into account
when choosing values for the current limit resistor
(RCL) and Zener Diode (DD1):
•The variation of the VBUS (in this case, -48V
nominal)
• The chip supply current needs for all functional
conditions
• The power rating of RCL.
• The current rating of DD1
Formulas
Sizing RCL is expressed in Equation 1:
Power Rating of RCL is expressed in Equation 2:
DD1 current rating is expressed in Equation 3:
Example:
A typical -48V supply may vary from -36 to -72V.
Therefore:
VBUS,MAX = -72V
VBUS,MIN = -36V
ICHIP = 15mA (Max)
Sizing RCL is expressed in Equation 4:
Power rating of RCL is expressed in Equation 5:
DD1 current rating is expressed in Equation 6:
