compensate for the differing beam path length as the
beam is swept from one side of the page to the other.
Undervoltage, overcurrent and over-temperature error
conditions are ORed together and made available on the
ERRB pin.
Power Supply Decoupling
Due to the high values of current being switched rapidly
on and off, it is important to ensure that the power
supply is well decoupled to ground. During switching, the
V CC undergoes severe current transients, thus every
effort should be made to decouple the V CC as close to
the package as possible. Symptoms that could arise
include poor rise/fall times, current overshoot, and poor
settling response. It is recomended that VCC inputs
should be bypassed with 4.7μF // 100nF // 470pF to
GND.
Inductance will be in series with the decoupling capacitor
at the rate of about 0.6nH/mm of trace or capacitor
distance. Thus for a 3mm loop from V CC through the
capacitor to ground, 300mA in 1ns will produce 540mV
transient on the V CC -GND voltage.
