Laser diode drivers from iC-Haus operate up to 155 MHz
The iC-NZN and iC-NZP laser diode drivers operate laser diodes in both CW and spike-free pulse mode up to 155 MHz, controlling either the optical output power (APC) or laser diode current (ACC) up to 300 mA. Features include an adjustable current limit, a safety shutdown function for the output stage that warns of overtemperature, LVDS or TTL pulse signals, and a standby mode with a low current consumption of <50 µA.

PRESS RELEASE
All-purpose laser diode driver
Driving laser diodes from CW to 155 MHz with power or current control
The all-purpose laser diode drivers iC-NZN and iC-NZP operate laser diodes in both CW and spike-free pulse mode with up to 155 MHz. The devices allow either the optical output power (APC) or laser diode current (ACC) to be controlled. In ACC mode also laser diodes without monitor diodes can be used. Blue laser diodes can also be operated with iC-NZN. The maximum available laser diode current is 300 mA. The devices have an adjustable current limit.
When the current limit is reached, this is signaled at an error message output which also indicates undervoltage and overtemperature. There is a safety shutdown function for the output stage in the event of overtemperature.
The device can be driven by either LVDS or TTL pulse signals.
iC-NZN and iC-NZP have a standby mode with a low current consumption of < 50 µA.

Introducing iC-Haus
iC-Haus GmbH is a leading independent German manufacturer of standard iCs (ASSP) and customized ASiC semiconductor solutions. The company has been active in the design, production, and sales of application-specific iCs for industrial, automotive, and medical technology since 1984 and is represented worldwide. The iC-Haus cell libraries in CMOS, bipolar, and BCD technologies are fully equipped to realize the design of sensor, laser/opto, and actuator ASiCs.
The iCs are assembled either in standard plastic packages or using chip-on-board technology to manufacture complete microsystems, multichip modules and optoBGATM, the latter in conjunction with sensors.
