Description Features
 
Laser Switch iC-HK/B enables the spike-free switching of laser diodes with well-defined current pulses at frequencies ranging from DC to 155 MHz. The diode current is determined by the voltage at pin CI and by the resistors RK1 and RK2. The two fast switches are controlled independently via CMOS inputs EN1 and EN2. The laser diode can thus be turned on and off or switched between different current levels defined by the ratio of RK1 and RK2. Each channel can be operated on 150 mA DC and up to 700 mA pulsed current depending on the frequency, duty cycle and heat dissipation. The integrated thermal shutdown feature prevents damage from excessive temperature. iC-HK/B supplements the laser diode driver iC-WK which uses the monitor current of the laser diode to control the laser power. iC-WK therefore controls the voltage at pin CI in such a way that the mean value of the emitted laser power is constant (APC), providing there is a constant duty cycle and a switching frequency higher than 100 kHz.
