Eye Safety
The ADNS-7550 integrated molded lead-frame DIP sensor
and the associated components are intended to comply
with Class 1 Eye Safety Requirements of IEC 60825-1. Avago
Technologies suggests that manufacturers perform
testing to verify eye safety on each mouse. It is also rec-
ommended to review possible single fault mechanisms
beyond those described below in the section “Single
Fault Detection”. Under normal conditions, the sensor
generates the drive current for the VCSEL.
In order to stay below the Class 1 power requirements,
LASER_CTRL0 (register 0x1a), LASER_CTRL1 (register
0x1f ), LSRPWR_CFG0 (register 0x1c) and LSRPWR_CFG1
(register 0x1d) must be programmed to appropriate
values. The ADNS-7550 integrated molded lead-frame
DIP sensor which comprised of the sensor and VCSEL;
is designed to maintain the output beam power within
Class 1 requirements over components manufacturing
tolerances and the recommended temperature range
when adjusted per the procedure below and implement-
ed as shown in the recommended application circuit
of Figure A1. For more information, please refer to Eye
Safety Application Note 5361.
