iC-WJB EVAL WJ1D is the evaluation board for evaluating, testing, and measuring of iC-WJB.
The iC-WJB is a driver IC for laser diodes in continuous or pulsed operation of up to 300 kHz. The wide power supply range of 2.7 to 6 V and the integrated reverse battery protection allows for battery-operation with two to four AA/AAA cells.
An external resistor at ISET is employed to adapt the APC to the laser diode being used. The capacitor at CI determines the recovery time constants and the starting time.
A watchdog circuit monitors the switching input IN.
