Disabling the LASER
LASER_NEN is connected to the gate of a P-channel
MOSFET transistor which when ON connects V
LASER. In normal operation, LASER_NEN is low. In the
case of a fault condition (ground or V
LASER_NEN goes high to turn the transistor off and
disconnect V
Single Fault Detection
ADNS-6030 is able to detect a short circuit or fault
condition at the XY_LASER 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. When used in combination with external
components as shown in the block diagram below, the
system will prevent excess laser power for a resistive
path to ground at XY_LASER by shutting off the laser. In
addition to the ground path fault detection described
above, the fault detection circuit is continuously checked
for proper operation by internally generating a path to
ground with the laser turned off via LASER_NEN. If the
XY_LASER pin is shorted to V
