Single Fault Detection
ADNS-6010 is able to detect a short circuit, or fault,
condition at the RBIN and XY_LASER pins, which could
lead to excessive laser power output. A low resistance
path to ground on either of these pins 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 single short to ground
at RBIN or XY_LASER by shutting off the laser. Refer to the
PC board layout notes for recommendations to reduce
the chance of high resistance paths to ground existing
due to PC board contamination.
In addition to the continuous fault detection described
above, an additional test is executed automatically
whenever the LP_CFG0 register is written to. This test
