Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
(1)
Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
Note
• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluations. Typical values are for information only and are not part of the testing requirements.
Note
(1)
f = 1.0 kHz, pulse width = 100 μs, load (R
L
) = 1.0 MΩ, 15 pF; measured at 90 % rated voltage (t
on
), 10 % rated voltage (t
off
). Actuation speed
depends upon the external t
on
and t
off
circuitry and the capacitance of the MOSFET.
FUNCTIONAL DESCRIPTION
Figure 1 outlines the IV characteristics of the illuminated photodiode array (PDA). For operation at voltages below V
OC
, the PDA
acts as a nearly constant current source. The actual region of operation depends upon the load.
The amount of current applied to the LED (pins 1 and 2 or 3 and 4) determines the amount of light produced for the PDA. For
high temperature operation, more LED current may be required.
