Eye Safety
ADNS-7630 SoC sensor and the associated components
in the schematic of Figure 9 are intended to comply with
Class 1 Eye Safety requirements of IEC/EN 60825-1. Avago
Technologies pre-calibrate sensor laser output power
(LOP) to Class 1 eye safety level prior shipping out, thus no
laser output power calibration is required at mouse manu-
facturer site.
ADNS-7630 SoC sensor is designed to maintain the laser
output power using ADNS-7100-001 lens within Class 1
requirements over components manufacturing tolerances
under the recommended operating conditions and ap-
plication circuit of Figure 9 as specified in this document.
Under normal operating conditions, the sensor generates
the drive current for the VCSEL. For more information,
please refer to Eye Safety Application Note.
Single Fault Detection
ADNS-7630 SoC sensor is able to detect a short circuit
or fault condition at the –VCSEL pin, which could lead to
excessive laser power output. A path to ground on this
pin will trigger the fault detection circuit, which will turn
off the laser drive current source and set the LASER_NEN
output high. The system will prevent excess laser power
Absolute Maximum Ratings
Notes:
1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are the stress ratings
2. The inherent design of this component causes it to be sensitive to electrostatic discharge. The ESD threshold is listed above. To prevent ESD-

for a resistive path to ground at -VCSEL by shutting off the
laser. In addition to the ground path fault detection de-
scribed above, the fault detection circuit is continuously
checking for proper operation by internally generating a
path to ground with the laser turned off via LASER_NEN. If
the –VCSEL pin is shorted internally to VDD3, this test will
fail and will be reported as a fault.
