Typical Characteristics (cont.)
Power Dissipation
The maximum allowable power dissipation of the device for normal
operation (P
MAX
), is a function of the package junction to ambient thermal
resistance (?/DIV>
JA
), maximum junction temperature (T
JMAX
), and ambient
temperature (T
AMB
), according to the
expression:
P
MAX
= (T
JMAX
T
AMB
) / ?/DIV>
JA
The device power dissipation, P
D
is given by the expression:
P
D
= I

Application Information
The following text describes how to scale a load current to an
output voltage.
V
SENSE
= V
IN
- V
LOAD
V
OUT
= 0.01 x V
SENSE
x R
OUT
1
E.g.
A 1A current is to be represented by a 100mV output voltage:
1) Choose the value of R
SENSE
to give 50mV >
V
SENSE
> 500mV at full load.
For example V
SENSE
= 100mV at 1.0A.
R
SENSE
= 0.1/1.0 => 0.1&.
2) Choose R
OUT
to give V
OUT
= 100mV, when
V
SENSE
= 100mV.
Rearranging
1
for Rout gives:
R
OUT
= V
OUT
/(V
SENSE
x 0.01)
R
OUT
= 0.1 / (0.1 x 0.01) = 100&
