iC-HTP Dual CW P-Type Laser Diode Driver
●iC-HTP is suitable for CW laser driver applications with one or two laser diodes of up to 1.5 A or 2x 750 mA.
●The IC requires only very few external components: a low cost microcontroller and the laser diode(s).
●The driver is completely controllable and monitorable with a microcontroller via SPI or I2C.
●Laser control can be APC (Automatic Power Control) or ACC(Automatic Current Control), or the connected microcontroller takes over parameter control digitally.
●Features
■Up to 750 mA per channel,up to 1500 mA with joined channels
■2.8V to 11 V power supply
■Operation with or without microcontroller
■Individual enable input per channel
■Control loop accuracy better than 1%
■Internal programmable logarithmic monitor resistor
■Operating point setup with 10 bit logarithmic resolution
■Current or laser-power control (ACC or APC) per channel
■Analog level monitoring by A/D converter (per channel)
■Serial programming interface (SPI or I²C compliant)
■Configuration content verification and validation
■Programmable laser overcurrent shutdown
■Optimized for P-type laser diodes or dual common cathode
■Low-drop linear regulator output for 33 V (10 mA)
■Low-power standby mode
■On-chip temperature sensing
■Operating temperature range of -40°C to 85 °C
