The voltage V

SET

at the test point VSET must be set according to the laser operating voltage and current:

DRV200S-A-40 safe operating area

DRV200S-A-200 safe operating area

DRV200S-A-400 safe operating area

SET

can be adjusted between 2.4 V and 18 V with the VSET trimmer. When the board is powered off, adjust the

voltage V

SET

by using the formula V

SET

= R

SET

× I

SET

, where R

SET

is the resistance between GND and the VSET

testpoint and I

SET

= 100 µA for the DRV200-A-40 and the DRV200-A-200 and 200 µA for the DRV200-A-400.
