B1675 Miniature DPSS Laser Driver

(print-friendly format) PDF


The Kigre B1675 is a Bluetooth® compatible, miniature driver optimized for the Kigre DPSS family of lasers, including the MK11, MK81, MK82 and MK85. The driver provides 100A square pulses of current (up to 3mS) with typical I/O efficiency of 92%.

Features include reverse input voltage and current protection, under-voltage (UVP) and over-voltage (OVP) protection, and soft-start input current ramp-up for battery applications.

Advanced laser diode protection, external photodiode bias (for pump-current shutoff), and short-circuit output protection are also included.
